Résumé :
Linking to the S element hybrid strategies, S-doped carbon materials having different macrostructures and defect concentrations are prepared by using sulfur and coal-tar-pitch as raw materials in a carbonization temperature range of 700–1000 °C. The evaluations of macrostructure and surface characteristics are performed through XRD, TEM, Raman and XPS measurements. Through the linear fitting among the Na+ storage capacity with ID/IG and d002 values, the correlations of Na+ storage capacity with macrostructures and defects are respectively investigated in detail. It is observed that S-doped carbon materials exhibit storage capacity at 120 mAh/g after the charge-discharge is being carried out 2000 cycles at 2.0 A/g. Studies have shown that adsorptions of introduced defects on graphene-like carbon sheets mainly play the role to enhance the storage capacity, and the expanded carbonaceous lamellar spaces of highly disordered and pseudo-graphitic macrostructures provide the channels for fast transfer of Na+. Our studies are able to provide references for designs and fabrications of coal tar pitch based soft carbon materials as sodium-ion batteries (SIBs) anodes when using heteroatoms doping methods.

Résumé :
The rapid development of graphene-based nanotechnologies in recent years has drawn extensive attention in environmental applications, especially for water treatment. Three-dimensional graphene-based macrostructures (GBMs) have been considered to be promising materials for practical water purification due to their well-defined porous structure and integrated morphology, and displayed outstanding performance in pollutant abatement with easy recyclability. Three-dimensional GBMs could not only retain the intrinsic priorities of 2D graphene, but also emerge with extraordinary properties by structural manipulation, so rational design and construction of 3D GBMs with desirable microstructures are important to exploit their potential for water treatment. In this review, some important advances in surface modification (chemical doping, wettability, surface charge) and geometrical control (porous structure, oriented arrangement, shape and density) with respect to 3D GBMs have been described, while their applications in water purification including adsorption (organic pollutants, heavy metal ions), catalysis (photocatalysis, Fenton-like advanced oxidation) and capacitive desalination (CDI) are detailly discussed. Finally, future challenges and prospective for 3D GBMs in water purification are proposed.

Résumé :
A large number of methodologies for fabrication of 1D carbon nanomaterials have been developed in the past few years and are extensively described in the literature. However, for many applications, and in particular in catalysis, a translation of the materials to a macro-structured form is often required towards their use in practical operation conditions. This review intends to describe the available methods currently used for fabrication of such macro-structures, either already applied or with potential for application in the fabrication of macro-structured catalysts containing 1D carbon nanomaterials. A review of the processing methods used in the fabrication of macrostructures containing 1D sp2 hybridized carbon nanomaterials is presented. The carbon nanomaterials here discussed include single- and multi-walled carbon nanotubes, and several types of carbon nanofibers (fishbone, platelet, stacked cup, etc.). As the processing methods used in the fabrication of the macrostructures are generally very similar for any of the carbon nanotubes or nanofibers due to their similar chemical nature (constituted by stacked ordered graphene planes), the review aggregates all under the carbon nanofiber (CNF) moniker. The review is divided into methods where the CNFs are synthesized already in the form of a macrostructure (in situ methods) or where the CNFs are previously synthesized and then further processed into the desired macrostructures (ex situ methods). We highlight in particular the advantages of each approach, including a (non-exhaustive) description of methods commonly described for in situ and ex situ preparation of the catalytic macro-structures. The review proposes methods useful in the preparation of catalytic structures, and thus a number of techniques are left out which are used in the fabrication of CNF-containing structures with no exposure of the carbon materials to reactants due to, for example, complete coverage of the CNF. During the description of the methodologies, several different macrostructures are described. A brief overview of the potential applications of such structures in catalysis is also offered herein, together with a short description of the catalytic potential of CNFs in general.

Résumé :
Carbon materials and their allotropes have been involved significantly in our daily lives. Zero-dimensional (0D) fullerenes, one-dimensional (1D) carbon materials, and two-dimensional (2D) graphene materials have distinctive properties and thus received immense attention from the early 2000s. To meet the growing demand for these materials in applications like energy storage, electrochemical catalysis, and environmental remediation, the special category, i.e., three-dimensional (3D) structures assembled from graphene sheets, has been developed. Graphene oxide is a chemically altered graphene, the desired building block for 3D graphene matter (i.e., 3D graphene macrostructures). A simple synthesis route and pore morphologies make 3D reduced-graphene oxide (rGO) a major candidate for the 3D graphene group. To obtain target-specific 3D rGO, its synthesis mechanism plays an important role. Hence, in this article, we will discuss the general mechanism for 3D rGO synthesis, vital procedures for fabricating advanced 3D rGO, and important aspects controlling the growth of 3D rGO.

Résumé :
Designing hydrophobic-oleophilic sorbent materials have gained significant interest owing to its potential applications in self-cleaning technologies particularly oil-water separation. The crucial factors remain in the future research of designing materials with high performance hydrophobicoleophilic properties include facile synthesis, low-density, reusability and ecofriendly. Herein, we develop porous hydrophobic-oleophilic nanoarchitecture based on 2D fluorinated graphene (FG) supported cobalt based zeolite imidazole framework (ZIF-67) by solution assisted self-assembly. The key features of the work include in-situ growth and assembly of ZIF-67 over functionalized fluorinated graphene f-FG macrostructures, high surface area and solution processable and spray coated sponge. Methodical characterization of f-FG@ZIF-67 composites, followed by measuring water contact angles by contact angle goniometer. Furthermore, the assessment of sorption capacity of oils and organics followed by oil recovery from oil-water mixtures, excellent chemical and physical stabilities were displayed by these hydrophobic-oleophilic composites.

Résumé :
A high-performance magnesium oxychloride cement (MOC) composite composed of silica sand, diatomite powder, and doped with graphene nanoplatelets was prepared and characterized. Diatomite was used as a 10 vol.% replacement for silica sand. The dosage of graphene was 0.5 wt.% of the sum of the MgO and MgCl2·6H2O masses. The broad product characterization included high-resolution transmission electron microscopy, X-ray diffraction, X-ray fluorescence, scanning electron microscopy and energy dispersive spectroscopy analyses. The macrostructural parameters, pore size distribution, mechanical resistance, stiffness, hygric and thermal parameters of the composites matured for 28-days were also the subject of investigation. The combination of diatomite and graphene nanoplatelets greatly reduced the porosity and average pore size in comparison with the reference material composed of MOC and silica sand. In the developed composites, well stable and mechanically resistant phase 5 was the only precipitated compound. Therefore, the developed composite shows high compactness, strength, and low water imbibition which ensure high application potential of this novel type of material in the construction industry.

Résumé :
ABSTRACT2D nanomaterials, when assembled into an ordered macrostructure, will present many great opportunities, including for Li-ion batteries (LIBs). We report densely-packed vertically-aligned VO2(B) nanobelts (NBs)-based forest structure synthesized on edge-oriented graphene (EOG) network. Using a EOG/Ni foam as a 3D scaffold, aligned VO2(B) NBs can be further synthesized into a folded 3D forest structure to construct a freestanding electrode for LIBs. Electrochemical studies found that such a freestanding VO2(B)/EOG electrode, which combines the unique merits of 2D VO2(B) NBs and 2D graphene sheets, has excellent charge-discharge rate performance. A discharge capacity of 178 mAh g-1 at a rate of 59 C and 100 mAh g-1 at 300 C was measured. A good charge-discharge cycling stability under a high current density was also demonstrated. The results indicate VO2(B)/EOG forest based freestanding electrode is very promising for developing high-rate LIBs.

Résumé :
Flexible, stretchable, wearable, and stable electronic materials are widely studied, owing to their applications in wearable devices and the Internet of Things. Because of the demands for both strain-insensitive resistors and high gauge factor (GF) strain-sensitive materials, anisotropic strain sensitivity has been an important aspect of electronic materials. In addition, the materials should have adjustable strain sensitivities. In this work, such properties are demonstrated in reduced graphene oxide (RGO) with hierarchical oriented wrinkle microstructures, generated using the two-step shrinkage of a rubber substrate. The GF values range from 0.15 to 28.32 at 100% strain. For device demonstrations, macrostructure patterns are designed to prepare patterned wrinkling graphene at rubber substrate (PWG@R). Serpentiform curves can be used for the constant-value resistor, combined with the first-grade wrinkles. Strip lines can increase the strain-sensing property, along with the second-grade wrinkles. The patterned sensor exhibits improved GF values range from 0.05 to 49.5. The assembled sensor shows an excellent stability (>99% retention after 600 cycles) with a high GF (49.5). It can monitor the vital signs of the throat and wrist and sense large motions of fingers. Thus, PWG@R-based strain sensors have great potential in various health or motion monitoring fields.

Résumé :
Three-dimensional (3D) graphene-based macrostructures are being developed to combat the issues associated with two-dimensional (2D) graphene materials in practical applications. The 3D macrostructures (3DMs), for example, membranes, fibres, sponges, beads, and mats, can be formed by the self-assembly of 2D graphene-based precursors with exceptional surface area and unique chemistry. With rational design, the 3D macrostructures can then possess outstanding properties and exclusive structures. Thanks to various advantages, these macrostructures are competing in a variety of applications with promising performances unlike the traditional activated carbons, biochars and hydrochars, which have less flexibilities for modifications towards versatile applications. However, despite having such a wide range of applications, 3DMs remain applicable on laboratory scale due to the associated factors like cost and extensive research. This perspective provides an overview of available graphene-based macrostructures and their diverse synthesis protocols. In the synthesis, hydrothermal route, chemical vapor deposition (CVD), wet spinning, 3D printing, vacuum filtration, spray drying and emulsion methods are highlighted. In addition, the physio-chemical properties of these macrostructures are discussed with the relationship among the porosity, surface area and the bulk density. The perspective also highlights the versatile potentials of different 3DMs in wastewater remediation by adsorption, desalination, and catalytic oxidation, etc. Following the concluding remarks, future outlooks on commercial applications of 3DMs are also provided.

Carbon-based flexible wearable sensors have received widespread attention due to their wide application in wearable electronics. This work reviewed the different carbon-based sensors from three aspects, such as fabrication, performance and working mechanisms. Carbon materials mainly included carbon nanotubes, graphene, carbon black and other carbon materials. In particular, carbon nanotubes and graphene can be assembled into various multiscale macrostructures to prepare various forms of flexible sensors, such as films, fibers, yarns or fabrics. Up to now, the reviewed flexible strain sensors in general exhibit high sensitivity, wide sensing range, fast response, long-term stability and durability. However, in the face of complex environmental and multifunctional integration in practical applications, wearable strain sensors need new technological breakthroughs in the preparation process, material synthesis and device integration.

In this study, graphene was efficiently dispersed in a solvent and filled into silicon rubber (SR), which was forward embedded-printed as a flexible strain resistance sensor (FSRS) with functional macrostructure and modified microstructure. Comprehensively considering the environmental protection of dispersion solvent and the cost of surfactants, a stable dispersion of graphene was established in an ultrasound-aided ball milling process, where absolute ethanol was selected as the solvent and sodium dodecyl sulfonate (SDS) as the surfactant. The printed pattern of graphene-filled conductive silicon rubber (CSR) was optimized and embedded-printed as the conductive sensitive material (CSM), in which the FSRS with a spiral-patterned CSM was chosen for its high sensitivity. Micropores with an optimized interspacing of 10 mm were further introduced into the spiral CSM to significantly improve the sensitivity (GF=51±4) of the fabricated FSRS at a considerable working strain (20~30%) and long-life working duration (>104 cycles). The FRSR was sensitive enough to capture various motions of single and multi-joints and identify the rhythm of played music, which exhibited its potential application as a wearable flexible sensor.
