WO3-based catalysts for photocatalytic and photoelectrocatalytic removal of organic pollutants from water - A review

Photoelectrocatalysis (PEC) is an advanced oxidation water treatment technology which combines the strengths of both heterogeneous photocatalysis and anodic oxidation for the effective degradation of organic pollutants in water. At the heart of this technology is the search for photocatalytic materials that exhibit excellent photo (electro)catalytic properties. In this article, we reviewed studies on WO3, one of the most promising photocatalysts for solar water treatment technology. Specific attention was paid to its properties, synthesis/preparation methods and strategies for improving its performance. Discussions were presented on some reports wherein the semiconductor and/or its composites were used to catalyse the degradation of organic pollutants in water.
