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.
