Abstract:
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.

Abstract:
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.

Abstract:
The Pt-W(lOO) system has been studied using Auger spectroscopy. X-ray photoelectron spectroscopy and X-ray photoelectron diffraction. Several different regimes were discerned and characterized; a pseudomorphic first Pt layer, distorted hexagonal Pt overlayers, 3D Pt microcrystallites and alloy films. XPS indicated electron transfer from Pt to W at the W/Pt interface and in the alloy layers. Surface Pt inhibits the dissociative chemisorption of CO via an ensemble effect resulting in enhanced molecular adsorption. Distortion in the pseu-dohexagona! layer results in CO bonding to Pt not typical of Pt(l 11). On alloy films CO appears to bind only at W sites with the bonding modified by neighbouring Pt atoms (ligand effect). Surface Pt inhibits adsorption and dissociation of hydrogen on W. At submonolayer coverages there is evidence for occupation of mixed W-Pt sites. Pseudomorphic Pt shows H2 desorption behaviour not typical of pure Pt surfaces while thicker layers resemble Pt(lll). In the presence of large quantities of Pt, H2 desorption from W sites occurs in a new feature at 270K. In the presence of adsorbed CO, the H2 desorption features are shifted to lower temperature, while CO seems little affected by hydrogen. In some cases new H2 desorption features indicate some local mixing of adsorbed CO and hydrogen. Low coverages of methanol or formaldehyde on W(100) lead to CO and H2 as the only decomposition products while at higher coverages, complexes giving rise to desorption of H2, Co, CH4, H2CO and CH3OH are formed. Small quantities of surface Pt eliminate the formation of these complexes. Methane is also formed via a different intermediate which is observed for Pt coverages < 0.5ML. At higher Pt loadings, adsorption of methanol or formaldehyde on W is inhibited. Thick Pt layers behave like pure Pt surfaces towards decomposition of methanol or formaldehyde giving CO and H2 only as decomposition products. On alloy surfaces, there is evidence for the formation of an H/CO complex with methanol decomposition but not with formaldehyde.

Full text
Abstract:
The unique Cambridge single crystal adsorption microcalorimeter has been applied to a range of systems of catalytic interest to extract fundamental thermodynamic data. Coverage-dependent adsorption heats and sticking probabilities have been obtained with CO, NO, oxygen and ethylene adsorbates and Pt{110}, Ni{100}, Ni{110} and K/Ni{110} substrates. The initial adsorption heats for CO, NO, and O2 on Pt{110} are 183, 160 and 335 kJ mol⁻¹ respectively. Catalytic heat of reaction data for CO + O2 on Pt{110}, the first obtained on a single crystal surface, suggest that "hot" adatoms are involved in producing thermally excited CO2 product molecules. The first measurement of the heat of adsorption of a hydrocarbon on a single crystal surface has been made for ethylene on Pt{110}. The initial value of 200 kJ mol⁻¹, together with coverage dependent values, yield an average Pt–C binding energy of 231 kJ mol⁻¹. A detailed comparison of new data for oxygen adsorption on Ni{100} and Ni{110} with existing data for Ni{111} is presented, with initial adsorption heats of 550, 475 and 440 kJ (mol O2) -1 respectively, while the corresponding sticking data suggest that the oxide film created is four atomic layers thick in each case. Novel temperature-dependent data have been successfully collected using a pyroelectric detector for oxygen on Ni{100} at 100, 300 and 410 K with a Monte Carlo simulation of the highest-temperature data yielding a strong second-nearest neighbour interaction energy of +30 ± 5 kJ mol⁻¹. The adsorption of CO on K-predosed Ni{110} was found to differ markedly from previous data collected on Ni{100} for potassium coverages up to 0.35 ML, with the adsorption heat promoted by only ~ 30 kJ mol⁻¹ compared to ~ 180 kJ mol⁻¹ for the {100} surface, a difference ascribed to the missing row reconstruction of Ni{110}.

Abstract:
Catalytic combustion of hydrogen-air boundary layers involves the adsorption of hydrogen and oxygen into a platinum coated surface, chemical reactions of the adsorbed species and the desorption of the resulting products. Re-adsorption of some produced gases is also possible. The catalytic reactions can be beneficial in porous burners and catalytic reactors that use low equivalence ratios. In this case the porous burner flame can be stabilized at low temperatures to prevent any substantial gas emissions, such as nitrogen oxides. The present paper is concerned with the numerical computation of heat transfer and chemical reactions in hydrogen-air mixture boundary layers that flow over platinum coated hot plates. Chemical reactions are included in the gas phase as well as on the solid platinum surface. In the gas phase, eight species are involved in 26 elementary reactions. On the platinum hot surface, additional surface species are included that are involved in 14 additional surface chemical reactions. The platinum surface temperature is fixed, while the properties of the reacting flow are computed. The flow configuration investigated in the present paper is that of a parallel boundary layer. Finite-volume equations are obtained by formal integration over control volumes surrounding each grid node. Hybrid differencing is used to ensure that the finite-difference coefficients are always positive or equal to zero to reflect the real effect of neighboring nodes on a typical central node. The finite-volume equations are solved, iteratively, for the reacting gas flow properties. On the platinum surface, surface species balance equations, under steady-state conditions, are solved numerically. A non-uniform computational grid is used, concentrating most of the nodes in the boundary sub-layer adjoining the catalytic surface. The computed OH concentration is compared with experimental and numerical data of similar geometry. The obtained agreement is fairly good, with differences observed for the location of the peak value of OH. Surface temperature of 1170 K caused fast reactions on the catalytic surface in a very small part at the leading edge of the catalytic flat plate. The computational results for heat and mass transfer and chemical surface reactions at the gas-surface interface are correlated by non-dimensional relations.

Abstract:
Catalytic combustion of hydrogen-air mixtures involves the adsorption of the fuel and oxidant into a platinum surface, chemical reactions of the adsorbed species and the desorption of the resulting products. Re-adsorption of some produced gases is also possible. The catalytic reactions can be beneficial in porous burners that use low equivalence ratios. In this case the porous burner flame can be stabilized at low temperatures to prevent any substantial gas emissions, such as nitric oxide. The present paper is concerned with the numerical computation of heat transfer and chemical reactions in flowing hydrogen-air mixtures axisymmetrically around a platinum-coated thin cylinder. Chemical reactions are included in the gas phase and in the solid platinum surface. In the gas phase 8 species are involved in 24 elementary reactions. On the platinum hot surface, additional surface species are included that are involved in 14 additional surface chemical reactions. The platinum surface temperature is fixed, while the properties of the reacting flow are computed. The flow configuration investigated here is the parallel boundary layer reacting flow over a cylinder. Finite-volume equations are obtained by formal integration over control volumes surrounding each grid node. Up-wind differencing is used to ensure that the influence coefficients are always positive to reflect the physical effect of neighboring nodes on a typical central node. The finite-volume equations are solved iteratively for the reacting gas flow properties. On the platinum surface, surface species balance equations, under steady-state conditions, are solved numerically by an under-relaxed linear algorithm. A non-uniform computational grid is used, concentrating most of the nodes near the catalytic surface. Surface temperatures, 1150 K and 1300 K, caused fast reactions on the catalytic surface, with very slow chemical reactions in the flowing gas. These slow reactions produce mainly intermediate hydrocarbons and unstable species. The computational results for the chemical reaction boundary layer thickness and mass transfer at the gas-surface interface are correlated by non-dimensional relations, taking the Reynolds number as the independent variable. Chemical kinetic relations for the reaction rate are obtained which are dependant on reactants concentrations and surface temperature.

Full text
Abstract:
A three-dimensional mathematical model of PEM fuel cell operated on reformate is developed based on our previous established fuel cell model (Zhou and Liu, 2001), by incorporating the adsorption and oxidation kinetics of CO on platinum surface proposed by Springer et al (1997, 2001). This model is capable of studying the effect of CO poisoning as well as the hydrogen dilution effect by inert gases. The adsorption and oxidation kinetics of CO on platinum surface are incorporated in the source terms of the species equations, thus basic form of the mathematical equations are the same as those used for PEM fuel cell operated on pure hydrogen. With this model, we can obtain detailed information on the CO poisoning and variation of CO and hydrogen concentrations inside the anode. The modeling results from this 3D model revealed many new phenomena that cannot be obtained from previous 1D or 2D models. The model can be used to provide guidance for anode design optimizations. In the paper, results of the effects of various operating and design parameters, such as anode flow rate, gas diffuser porosity, gas diffuser thickness, and the width of the collector plate shoulder, are also presented.

Abstract:
Ordered mesoporous carbon (OMC) has been prepared by impregnating the pores of the silica template (SBA-15) with liquid petroleum gas (LPG) or sucrose. The desired support (OMC) was obtained after dissolution with NaOH. Platinum nanoparticles were dispersed on ordered mesoporous carbons using Chemical Vapour Deposition (CVD) method and Pt(acac)2 as metal source. The resulting ordered mesoporous carbon possess a large surface area with high microporosity, and a controlled pore size distribution, High-quality carbon replicas of SBA-15 show an X-ray diffraction peak at low angle, which indicates that the structural periodicity of the (111) planes has been maintained. Their pore volume and specific surface area are high and the pore volume is almost entirely microporous. The synthesized Pt/OMC was characterized by powder X-Ray diffraction, HR-TEM, HR-SEM, EDS, thermogravimetric analysis, and nitrogen adsorption. The performance of Pt catalyst supported OMC was evaluated by electrochemical studies, which shows almost similar activity to the commercial catalyst.
