Large-scale synthesis of Au–WO3 porous hollow spheres and their photocatalytic properties

Abstract

Uniform Au–WO₃ porous hollow spheres have been synthesized on a large-scale by a general in situ reaction between weakly reductive carbonaceous microspheres and oxidative noble-metal precursors without foreign reducing agents and stabilizing agents. The hybrid materials exhibit excellent activity for visible-light photocatalytic degradation of organic pollutants.
