Carbon materials with developed porosity are usually used as supports for platinum catalysts. Physico-chemical characteristics of the support influence the properties of platinum deposited and its catalytic activity. In our studies, we deposited platinum on carbon fibrous like materials obtained from platanus seeds - achenes. The precursor was chemically activated with different reagents: NaOH, pyrogallol, and H2O2, before the carbonization process. Platinum was deposited on all substrates to study the influence of the substrate properties on the activity of the catalyst. Carbon materials were characterized by nitrogen adsorption/desorption isotherms measurements, X-ray diffraction, and scanning electron microscopy. It was noticed that the adsorption characteristics of carbon support affected the structure of platinum deposits and thus their activity.

The kinetics of the Fe2+ and Fe3+ oxidation-reduction reaction on a platinum electrode in 1 M HClO4 was investigated by the EIS method in the presence of hexylamine as a surfactant. With surfactant adsorption, the effective area of the solution-electrode interface decreases. A proportional increase in charge transfer resistance takes place. This resistance values obtained at various hexylamine concentrations. The surface coverage θ(R) for the solution-platinum interface have been calculated. The hexylamine adsorption at the solution-air interface was investigated by the maximum bubble pressure method. The surface tension γ at various hexylamine concentrations are obtained. The surface coverage θ(γ) for the solution-air interface has been calculated. The area occupied by the hexylamine molecule at the interface and the adsorption layer thickness are estimated. It is shown that adsorption process is described by the Dhar-Flory-Huggins isotherm at both interfaces. The slope tg α of the θ(R) and θ(γ) dependence on the hexylamine concentration is close to the theoretical unit in the Dhar-Flory-Huggins coordinates. The main parameters of the hexylamine adsorption (adsorption constant Kad, free adsorption energy ΔGad) were calculated for both interfaces (see Table). Solution-platinum interface Solution-air interface tg α 0.94±0.09 0.98±0.18 K ad / L mol-1 10.0±4.0 15.8±0.3 ΔG ad / kJ mol-1 –(14.8 ± 5.0) –(16.7±0.3) In the general case, the surfactant adsorption on a metal electrode can be due to the interaction of surfactant molecules with the metal or the hydrophobic effect of the surfactant displacement molecules onto the solution surface by polar water molecules. For the solution-air interface, the hydrophobic effect is the main reason for surfactant adsorption at this interface. The values of the main adsorption characteristics on both interfaces are close. Probably, the hydrophobic effect is also the predominant reason for the hexylamine adsorption on platinum. This assumption requires additional studies of the surfactant adsorption on other metals.

Platinum is a precious metal with many applications, such as: catalytic converters, laboratory equipment, electrical contacts and electrodes, digital thermometers, dentistry, and jewellery. Due to its broad usage, it is essential to recover it from waste solutions resulted out of different technological processes in which it is used. Over the years, several recovery techniques were developed, adsorption being one of the simplest, effective and economical method used for platinum recovery. In the present paper a new adsorbent material (XAD7-DB30C10) for Pt (IV) recovery was used. Produced adsorbent material was characterized by X-ray dispersion (EDX), scanning electron microscopy (SEM) analysis, Fourier Transform Infrared Spectroscopy and Brunauer-Emmett-Teller (BET) surface area analysis. Adsorption isotherms, kinetic models, thermodynamic parameters and adsorption mechanism are presented in this paper. Experimental data were fitted using three non-linear adsorption isotherms: Langmuir, Freundlich and Sips, being better fitted by Sips adsorption isotherm. Obtained kinetic data were correlated well with the pseudo-second-order kinetic model, indicating that the chemical sorption was the rate-limiting step. Thermodynamic parameters (ΔG°, ΔH°, ΔS°) showed that the adsorption process was endothermic and spontaneous. After adsorption, metallic platinum was recovered from the exhausted adsorbent material by thermal treatment. Adsorption process optimisation by design of experiments was also performed, using as input obtained experimental data, and taking into account that initial platinum concentration and contact time have a significant effect on the adsorption capacity. From the optimisation process, it has been found that the maximum adsorption capacity is obtained at the maximum variation domains of the factors. By optimizing the process, a maximum adsorption capacity of 15.03 mg g−1 was achieved at a contact time of 190 min, initial concentration of 141.06 mg L−1 and the temperature of 45 °C.

In this work, the adsorption of platinum (II, IV) chloride complexes from acidic solutions on silica gel modified with quaternary ammonium salts (QAS) was studied. The uptake of the platinum chloride complexes is caused by the formation of ionic (QAS+)2[PtCl x]2− ( x = 4, 6) associates on the surface of silica gel. The isotherms of adsorption are fitted by the Langmuir model. The maximum capacity for [PtCl4]2− and [PtCl6]2− is 0.99 and 1.13 mmol/g, correspondingly. The respective adsorption constants KL = 6.8 and 10 × 105 l/mol prove the high affinity of the adsorbates to the QAS-modified surface. Platinum metal nanoparticles supported on the surface of the silica gel were prepared by reducing the adsorbed platinum (II, IV) complexes. Such nanoparticles functioning at the moderate temperature regime have demonstrated a reasonable catalytic activity for the hydrogen and oxygen recombination, and an excellent stability over 35 cycles of the reaction.

Rice hull, a biomass waste product, and Lewatit TP 214, a thiosemicarbazide sorbent, were investigated as adsorbents for the adsorption of platinum (IV) ions from synthetically prepared dilute chloroplatinic acid solutions. The rice hull was characterized by Attenuated Total Reflection-Fourier transform infrared spectroscopy (ATR-FTIR). The effects of the different adsorption parameters, sorbent dosage, contact time, temperature and pH of solution on adsorption percentage were studied in detail on a batch sorption. The adsorption equilibrium data were best fitted with the Langmuir isotherm model. The maximum monolayer adsorption capacities, Qmax, at 25?C were found to be 42.02 and 33.22 mg g-1 for the rice hull and Lewatit TP 214, respectively. Thermodynamic calculations using the measured ?H?, ?S? and ?G? values indicate that the adsorption process was spontaneous and exothermic. The pseudo-first-order and pseudo-second-order rate equations were investigated; the adsorption of platinum ions for both sorbents was found to be described by the pseudo-second-order kinetic model. The kinetic rate, k2, using 30 mg sorbent at 25?C was found to be 0.0289 and 0.0039 g min-1 mg-1 for the rice hull and Lewatit TP 214, respectively. The results indicated that the rice hull can be effectively used for the removal of platinum from aqueous solution.

Hydrogen adsorption isotherms for (8, 0) platinum-decorated single-walled carbon nanotube were studied using molecular dynamics simulation. Adsorption isotherms were obtained for both internal and external surfaces of nanotube at several temperatures from 77 K up to 400 K. The results were compared with the bare nanotube at the same conditions. Adsorption coverage, isosteric heat, binding energy, hydrogen desorption, and readsorption were calculated for both internal and external surfaces of nanotube. At low temperatures, hydrogen molecules were adsorbed significantly, but at higher temperatures, thermal energies reduced this capacity. Under the same conditions, the platinum-decorated single-walled carbon nanotube hydrogen adsorption is significantly higher than the bare one.

Fourier transform infrared spectroscopy has been used to investigate the effect of added cations and anions on CO adsorption on platinum and palladium hydrosols. In general, anion effects on CO adsorption may be classified into three categories. In the first category, poisoning anions (e.g. CN−, SH−) block the surface against CO adsorption so that infrared spectra exhibit either no ν(CO)ads bands or ν(CO)ads bands at lower frequencies (< 2070 cm−1). In the second category, inert anions (e.g. the halides, citrate, EDTA2−) have no apparent effect on ν(CO)ads. The third category is characterised by anions such as PO43−, CO32−, or stearate ion which affect ν(CO)ads via the pH change that the dissolved anions cause in the metal hydrosol dispersion medium. Infrared spectra of platinum and palladium hydrosols in cyanide media were found to exhibit bands due to cyanate, tetracyanoplatinate(II), and tetracyanopalladate(II) arising from cyanide corrosion of the metal hydrosols. Ultraviolet/visible spectra of iodide ion in platinum hydrosols indicated that iodoplatinate(II) species had been produced. The band shape of ν(CO)ads at 2070 cm−1 in platinum hydrosols is found to be sensitive to the state of dispersion of the hydrosol particles. Bands due to CO adsorbed on hydrosol particles in either a completely or partially aggregated state are weaker and broader with a decreased value of ν(CO)ads relative to that of the unaggregated hydrosol. Key words: platinum hydrosols, palladium hydrosols, CO adsorption, infrared spectroscopy, added salts.

We use a coordination-based kinetics model to look at the kinetics of the turnover frequency (TOF) for the oxygen reduction reaction (ORR) for platinum nanoclusters. Clusters of octahedral, cuboctahedral, cubic, and icosahedral shape and size demonstrate the validity of the coordination-based approach. The Gibbs adsorption energy is computed using an empirical energy model based on density functional theory (DFT), statistical mechanics, and thermodynamics. We calculate the coordination and size dependence of the Gibbs adsorption energy and apply it to the analysis of the TOF. The platinum ORR follows a Langmuir–Hinshelwood mechanism, and we model the kinetics using a thermodynamic approach. Our modeling indicates that the coordination, shape, and the Gibbs energy of adsorption all are important factors in replicating an experimental TOF. We investigate the effects of size and shape of some platinum polyhedra on the oxygen reduction reaction (ORR) and the effect on the mass activity. The data are modeled quantitatively using lognormal distributions. We provide guidance on how to account for the effects of different distributions due to shape when determining the TOF.

The adsorption of hydrogen, as well as the interaction of adsorbed CO and hydrogen, on the Cu 3 Pt (111) surface have been studied using thermal desorption spectroscopy (TDS), high resolution electron energy loss spectroscopy (HREELS) and work function change measurements (ΔΦ). The results show that hydrogen adsorption and dissociation occur via platinum sites. The process proceeds with second order kinetics with respect to the number of platinum sites available. The desorption spectra are successfully simulated using a lattice gas model. From the simulations the desorption and lateral interaction energies are deduced, showing a weak hydrogen-hydrogen repulsion. The interaction of coadsorbed CO and hydrogen has also been investigated. In contrast to the Pt(111) surface where a lateral segregation of the two adsorbed species takes place, the results presented here suggest a mixed overlayer.

Adsorption is one of the electrochemical process stages often. The adsorption of polar organic molecules (surfactants) on metal electrodes is of significant interest. In particular, the surfactant adsorption affects the exchange current value and determines the metal corrosion rate. Therefore, the explanation of the adsorption mechanism is the most important problem in the investigation of the electrochemical kinetics. The kinetics of the Fe2+ and Fe3+ oxidation-reduction reaction on a platinum electrode in 1 M HClO4 was investigated by potentiodynamic and chronoamperometric methods in the presence of hexylamine as a surfactant. The main kinetic characteristics of the reaction (exchange current density, transfer coefficient, diffusion coefficients of iron ions) have been determined. The dependence of the exchange current density on the hexylamine concentration is analyzed. The surface coverage with a surfactant was estimated at various hexylamine concentrations. It was shown that the hexylamine adsorption on platinum is described by the Dhar-Flory-Huggins adsorption isotherm. The values of the adsorption constant and the adsorption free energy are obtained. These values are close to the corresponding values for the hexylamine adsorption on mild steel in hydrochloric acid. Consequently, the objective laws for the hexylamine adsorption depend low on the acid type and the electrode nature. This indicates the physical adsorption of the surfactant. It is possible that adsorption occurs due to the hydrophobic interaction of the surfactant molecules with polar water molecules. Then, the displacement of surfactant molecules to the interface takes place regardless of the nature of the acid and the metal contacting with the solution. The latter assumption requires further investigations of the surfactant adsorption on various metals.

The oxygen reduction reaction (ORR) on Pt/C in alkaline solution was studied by in situ high energy resolution X-ray absorption spectroscopy. To discuss the X-ray absorption near-edge structure (XANES), this paper introduced the rate of change of the Δμ (RCD), which is an analysis method that is sensitive to surface adsorption. The surface adsorptions as hydrogen (below 0.34 V), superoxide anion (from 0.34 V to 0.74 V), hydroxyl species (from 0.44 V to 0.74 V), atomic oxygen (above 0.74 V), and α-PtO2 (above 0.94 V) were distinguished. It is clarified that the catalytic activity in an alkaline solution is enhanced by the stability of atomic oxygen and the low stability of superoxide anion/peroxide adsorption on the platinum surface.
