Carbon nanotubes-based PdM bimetallic catalysts through N₄-system for efficient ethanol oxidation and hydrogen evolution reaction.

ABSTRACT: Transitional metal-nitrogen-carbon system is a promising candidate to replace the Pt-based electrocatalyst due to its superior activity, durability and cost effectiveness. In this study, we have designed a simple strategy to fabricate carbon nanotubes-supported binary-nitrogen-carbon catalyst via wet-chemical method. Palladium and transitional metals (M, i.e. manganese cobalt and copper) nanoparticles are anchored through four-nitrogen system onto carbon nanotubes (denoted as PdM-N₄/CNTs). This material has been used as bifunctional electrocatalyst for electrochemical ethanol oxidation reaction and hydrogen evolution reaction for the first time. The N₄-linked nanoparticles onto carbon nanotubes plays a crucial role in intrinsic catalytic activity for both reactions in
