Effect of platinum on Ceria supported Cu catalysts for PrOx process in fuel processors
The CO preferential oxidation (PrOx) is one of the critical steps in hydrogen production and purification for Polymer Electrolyte Membrane Fuel Cell (PEMFC). This reaction was investigated in the presence of excess hydrogen over Cu/CeO2, Pt/CeO2 and Cu-Pt/CeO2 catalysts. The ceria supports was prepared via precipitation method and Cu-Pt/CeO2 catalyst was synthesized by sequential impregnation o...
متن کاملCadmium-specific formation of metal sulfide 'Q-particles' by Klebsiella pneumoniae.
Klebsiella pneumoniae overcomes cadmium toxicity through the 'biotrans-formation' of cadmium ions into photoactive, nanometre-sized CdS particles deposited on the cell surface. The kinetics of particle formation during batch culture growth was monitored by electron microscopy (EM), energy-dispersive X-ray analysis and electronic absorption spectroscopy (EAS). During the deceleration phase of ba...
متن کاملEfficient hydrogen evolution by ternary molybdenum sulfoselenide particles on self-standing porous nickel diselenide foam
With the massive consumption of fossil fuels and its detrimental impact on the environment, methods of generating clean power are urgent. Hydrogen is an ideal carrier for renewable energy; however, hydrogen generation is inefficient because of the lack of robust catalysts that are substantially cheaper than platinum. Therefore, robust and durable earth-abundant and cost-effective catalysts are ...
متن کاملMicroemulsion-mediated Synthesis of Nanosize Molybdenum Sulfide Coal Liquefaction Catalysts
INTRODUCTION In heterogeneous catalysis, the size of the catalyst is of considerable importance in that the extent of reaction is often inversely proportional to the particle size of the catalyst. As a consequence, various methods have been used to synthesize particles of large specific surface area for catalysis applications (1-3). Most of these methods are based on hydrocolloids (1) and aeros...
متن کاملTi3C2 MXene co-catalyst on metal sulfide photo-absorbers for enhanced visible-light photocatalytic hydrogen production
Scalable and sustainable solar hydrogen production through photocatalytic water splitting requires highly active and stable earth-abundant co-catalysts to replace expensive and rare platinum. Here we employ density functional theory calculations to direct atomic-level exploration, design and fabrication of a MXene material, Ti3C2 nanoparticles, as a highly efficient co-catalyst. Ti3C2 nanoparti...
