Bimetallic electrocatalysts for hydrogen evolution and oxidation reaction in alkaline media

Abstract

The present work Focus on synthesizing platinum-based bimetallic catalysts with a metallic atomic ratio of 1:1, supported on ozone-treated carbon nanotubes, for applications in hydrogen evolution and hydrogen oxidation reactions in alkaline media. The synthesized materials are comprehensively characterized to determine their physical properties including structures, dispersion, and morphology.

Additionally, the chemical composition is measured to determine the output metallic ratio. Initial results indicate unsatisfactory outcomes, suggesting a need for further investigation.

The materials are extensively evaluated in term of their catalytic performances toward hydrogen evolution and hydrogen oxidation reactions in alkaline media. The primary objective is to establish a correlation between the oxophilicity of the second metal and the observed catalytic performances. Promising trends are being identified in the performance of the bimetallic catalyst, indicating the potential influence of the second metal on the catalyst's performance. However, further studies are required to validate these findings.
