Platinum is the most commonly used catalyst in fuel cell application. However, platinum is very expensive, thus limits the commercialisation of fuel cell system due to the cost factor. 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. Notably, the 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 m²g⁻¹, mass activity/specific activity (398.20 mAmg⁻¹/0.8471 mA/cm²_Pt) which greater than commercial Pt black (158.12 mAmg⁻¹/1.41 mA/cm²_Pt).

铂是燃料电池应用中最常用的催化剂。然而，铂非常昂贵，因此由于成本因素而限制了燃料电池系统的商业化。这项研究介绍了一种从植物提取物中生物合成铂的方法，与传统方法相比，该方法可以降低铂的生产成本，并且可以降低催化剂生产过程中的危险性。在直接甲醇燃料电池上测试了生物铂。Pt纳米簇的高级生物合成是通过一种新颖且简便的，以植物提取物为还原剂的天然来源的一锅合成生物还原技术来实现的。从农业废料中提取的几种精选植物提取物，例如香蕉皮，比较了菠萝皮和甘蔗渣提取物的丰富多酚植物化学来源对Pt NPs一步合成的开发能力。值得注意的是，甘蔗渣中的生物成因Pt NPs具有优异的电催化活性，增强的Pt利用效率和对甲醇氧化反应的明显稳定性，其ECSA值约为94.58 m。² g ^-1，质量活性/比活度（398.20 mAmg ^-1 /0.8471 mA / cm ² _Pt）大于市售Pt黑（158.12 mAmg ^-1 /1.41 mA / cm ² _Pt）。
