Synthesis of faceted β-SnWO4 microcrystals with enhanced visible-light photocatalytic properties

Abstract

Highly crystalline β-SnWO₄ truncated rhombic dodecahedrons with sharp edges and smooth faces are prepared via a wet-chemical route. The compound exhibits a much higher photocatalytic activity than spherical β-SnWO₄ nanoparticles or conventionally prepared bulk β-SnWO₄ as well as faceted microcrystals of m-BiVO₄ and Ag₃PO₄.
