Study on synthesis and characterization of electrocatalyst containing platinum on graphite electrode for hydrogen evolution reaction

Abstract

In this study, we have successfully synthesized electrode materials containing Pt on modified graphite by electrodeposition method, such as: Pt/C, Pt-Au/C Pt-Pd/C, Pt-Ni/C, Pt-Ni-Au/C, Pt-Ni-Pd/C. The formation of materials coating on the modified graphite surface is demonstrated through SEM, EDS results. Synthetic materials are used as catalysts for hydrogen evolution reaction (HER). The results show that Bimetallic composites containing Pt exhibit higher catalytic activity than the monometallic material Pt/C. Trimetallic materials Pt-Ni-Au/C and Pt-Ni-Pd/C have catalytic activity for HER insignificant lower than that of Pt-Au/C and Pt-Pd/C electrodes. However, the precious metal composition in the trimetallic composite material system is reduced, which is also an important goal of research and opens up prospects for the fabrication of next-generation composite materials systems.
