Multimetallic Pt-Based Alloy Nanowires Library as a Platform for Selective Electrocatalytic Oxidation of Ethylene Glycol
Source abstract
Abstract
While traditional Pt-based catalysts suffer from inadequate selectivity and stability in electrocatalytic ethylene glycol oxidation reactions, we present a general and scalable synthesis strategy, fabricating a broad multimetallic Pt-based alloy nanowires (NWs) library from binary to quinary. Among these, the PtAgCuRhRu NWs exhibit exceptional performance, with a mass activity ∼8 times higher than that of Pt/C and a Faradaic efficiency for glycolic acid (GA) reaching 93.49%. In the membrane electrode assembly electrolyzer, the catalyst maintained its activity over 140 h with 99% GA selectivity. In situ experimental and theoretical calculations reveal oxygenophilic Rh and Ru promote *OH adsorption, facilitating the conversion of *COCH 2 OH to GA and the oxidative removal of CO ads, enhancing activity and stability. Additionally, the high energy barrier for C–C bond cleavage suppresses undesired decomposition due to the introduction of Ag and Cu, leading to superior GA selectivity.
