In the process of developing highly active and stable Pt/C catalyst with low Pt loading for the reduction of oxygen in fuel cells, the metals are supported on porous carbon derived from natural resources such as plant bio mass, chitosan waste, straw, honeysuckles, coconut shells, orange peels, waste paper etc.1–4 Porous carbon derived from such sources are low cost and high specific surface area, well tuned textural properties, pore geometry renders towards prominent choice for support material through hetero atom doping to enhance the catalytic activity.5,6 In the present study Tamarind seeds (Tamarindus indica) utilized to derive the porous carbon for hetero atom doping followed by Pt deposition using traditional, liquid phase reaction (LPR) method.7 The synthesis process involves optimization of temperature, N-content in the catalyst followed by Pt loading by virtue of their electrochemical ORR behavior. The final optimized catalyst will be using in fuel cell as cathode catalyst. References W. Yang, Y. Zhai, X. Yue, Y. Wang, and J. Jia, Chem. Commun., 50, 11151–11153 (2014).T. Ramesh, N.
