Crystallization of Tungsten Trioxide Having Small Mesopores: Highly Efficient Photoanode for Visible‐Light‐Driven Water Oxidation

Abstract

Small mesopores are more efficient: A mesoprous oxide semiconductor (tungsten trioxide) having small mesopores was crystallized at high temperature (550 °C) by a simple one-step procedure. The highly crystalline mesoporous WO3 has an extremely high surface area which improves the visible-light-driven photoelectrochemical performance of water oxidation (see picture) relative to WO3 having interparticle mesopores.
