Abstract:
Researchers are exploring direct liquid fuel cells (DLFCs) as alternatives to proton-exchange membrane fuel cells because of their higher energy density and ease of storing and transporting the fuel. Direct borohydride fuel cells (DBFCs) are of particular interest as they offer a sustainable energy source with their high-power density output and the use of a highly alkaline NaBH4 medium [1]. Ensuring efficient and cost-effective catalysts for DBFCs is crucial for their commercial viability. Metal-organic frameworks (MOFs) have demonstrated significant potential as anodic electrocatalysts for B

Abstract:
Three different carbon-supported metal (gold, platinum, nickel) nanoparticle (M/c-IL) electrocatalysts are prepared by template-free carbonization of the corresponding ionic liquids, namely [Hmim][AuCl4], [Hmim]2[PtCl4], and [C16mim]2[NiCl4], as confirmed by X-ray diffraction analysis, scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy and Raman spectroscopy. The electrochemical investigation of borohydride oxidation reaction (BOR) at the three electrocatalysts by cyclic voltammetry reveals different behavior for each material. BOR is found to be a first-order react

Abstract:
Gold and silver nanoparticles in different atomic ratios deposited on reduced graphene oxide (AuAg/rGO-1, AuAg/rGO-2, and AuAg/rGO-3) were tested for the borohydride oxidation reaction in an alkaline medium. The morphology, structure, and composition of AuAg/rGO electrodes were investigated by transmission electron microscopy (TEM) and scanning electron microscopy with integrated energy dispersive spectroscopy (SEM-EDS). The TEM analysis showed that the most of gold and silver particles (more than 80%) are up to 9 nm in size, while slightly larger particles represent less than 5%. SEM-EDS show

Abstract:
The synthesis of palladium-based trimetallic catalysts via a facile and scalable synthesis procedure was shown to yield highly promising materials for borohydride-based fuel cells, which are attractive for use in compact environments. This, thereby, provides a route to more environmentally friendly energy storage and generation systems. Carbon-supported trimetallic catalysts were herein prepared by three different routes: using a NaBH4-ethylene glycol complex (PdAuNi/CSBEG), a NaBH4-2-propanol complex (PdAuNi/CSBIPA), and a three-step route (PdAuNi/C3-step). Notably, PdAuNi/CSBIPA yielded high

Abstract:
The electrochemical behavior of BH4- on Cu electrode in 1M NaOH was investigated by cyclic voltammetry(CV) in the potential range of -1.2V to 0.4V versus Hg/HgO. The CV results show that Cu electrode has obvious catalytic activities to the BH4- hydrolysis which belongs to ‘catalytic’ electrode materials. The BH4- electro-oxidation process on Cu is complex and it could associate with the BH4- hydrolysis reaction, followed by oxidation of the intermediate H, then, the intermediate product (e.g. BH3OH−) oxidized, and direct oxidation of BH4- at more positive potentials.

Abstract:
Le travail présenté dans cette thèse porte sur l'anode de la pile à combustible directe aux borohydrures (DBFC, selon l'acronyme anglais). Une première approche pour développer l'anode de la DBFC est d'étudier cette anode à l'intérieur du système global de la DBFC. Dans cette optique, des anodes composées des catalyseurs Pt/C et Pd/C ont été caractérisée en banc de test DBFC. D'autres facteurs ont aussi été étudiés, tels que la morphologie de l'anode et la stabilité des nanoparticules des catalyseurs.Le catalyseur d'anode de la DBFC doit idéalement exhiber une activité catalytique suffisante p

Les sites métalliques de Ni ont été identifiés comme les sites catalytiques pour la HHOR, la BOR et l'ABOR, tandis que la présence de sites de Ni (hydr)oxydés a un effet négatif sur l'activité sans influencer clairement le mécanisme réactionnel.
