Title:
ZINC OXIDE NANOROD ARRAY PHOTO-ANODE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/169017
Kind Code:
A1
Abstract:
A zinc oxide nanorod array photo-anode, which comprises a conductive substrate and a zinc oxide nanorod array grown on the conductive substrate, wherein the surface of the zinc oxide nanorod array has oxygen-rich vacancies, and the zinc oxide nanorod has a wire diameter of 50-500 nm and a height of 1-3 μm. The preparation method for the zinc oxide nanorod array photo-anode comprises the following steps: growing a zinc oxide nanorod array on a conductive substrate; and under an inert gas atmosphere, soaking the zinc oxide nanorod array in an electron solution to obtain a zinc oxide nanorod array photo-anode having oxygen-rich vacancies. The surface of the zinc oxide nanorod array having oxygen-rich vacancies has more active sites, which can improve the surface charge transfer of zinc oxide, such that the overall water splitting catalysis efficiency is improved.
