Abstract

The invention provides an indium-lead composite oxide nanowire and a preparation method and application thereof, the atomic ratio of In to Pb in the nanowire is 0.1-10, and the diameter of the nanowire is 10-300 nm. In the invention, the two metal components indium and lead generate a synergistic component effect and are applied to the electrochemical reduction process, so that the adsorption and activation of the raw materials are greatly enhanced. Different valence states of lead and indium are mutually adjusted, and the electronic structure of the catalyst is optimized. Meanwhile, more active sites can be exposed by the nanowire structure, and the reaction kinetics process is effectively improved by the three-dimensionally arranged nanoscale structure.
