Popis: Introduction: Platinum is the most commonly used catalyst in fuel cell application. However, platinum is very expensive, thus limits the commercialization of fuel cell system due to the cost factor. Objective: This study introduces a biosynthesis platinum from plant extracts that can reduce the cost of platinum production compared to the conventional method and the hazardous during the production of the catalyst. The biogenic platinum was tested on a Direct Methanol Fuel Cell. Advanced biogenic of Pt nano-cluster was synthesized through a novel and facile of one-pot synthesis bio-reduction derived from natural source in the form of plant extracts as reducing agent. Several selected plant extracts drawn from agricultural waste such as banana peel, pineapple peels and sugarcane bagasse extracts were comparatively evaluated on the ability of phytochemical sources of polyphenols rich for the development of single-step synthesis for Pt NPs. Conclusion: Biogenic Pt NPs from sugar cane bagasse has superior electro-catalytic activity, the enhanced utilization efficiency of Pt and appreciable stability towards methanol oxidation reaction, whose ECSA value approximates 94.58 m2g1, mass activity/specific activity (398.20 mAmg1/0.8471 mA/cm2 Pt) which greater than commercial Pt black (158.12 mAmg1/1.41 mA/cm2 Pt).
