Layered Pt.ZSM-5-C by Greener Chemical Reduction for Catalysing Fuel Cell Reactions

Metal ion exchanged catalysts are known now and are successfully used for many catalytic processes. But supported metal nanoparticles on the zeolite bed, and their use as catalysts is still under experimental probe. ZSM-5 supported platinum nanoparticles are synthesized from in-situ chemical reduction of platinum chloride solution in the presence of zeolite, by zinc dust chemical reduction method which is comparatively ‘greener’. This platinum nanoparticle loaded ZSM-5 is studied in the role of catalyst in electrooxidation of methanol and ethanol using Nafion-117 to bind the catalyst on carbon felt. The platinum nanoparticle loaded ZSM-5 is found to be a better catalyst compared to pure ZSM-5 and pure platinum. This greener chemical reduction method can be used as the results show that zeolite modified catalysts are as good as those prepared by other less environment friendly methods, if not better.
