Due to rapid industrialization and population growth, global energy shortage and environmental pollution have become two of the greatest challenges in society. Semiconductor-mediated photocatalysis, as a promising solution for these issues, has received tremendous attention, since it is a green and sustainable technology for degrading various organic pollutants and for splitting water into hydrogen and oxygen under the irradiation of sunlight. A prerequisite for the development of semiconductor photocatalysis is to obtain excellent photocatalysts. To date, a variety of semiconductor photocatalysts have been reported, such as TiO2, WO3, and Bi2O3. Many strategies have been applied to improve the photocatalytic performance such as doping, crystal facet engineering, morphology tailoring, defect introduction, metal deposition, and heterojunction construction. Great advances have been achieved on the structure–performance relationship in photocatalysts. However, the exploration of excellent photocatalysts for practical application is still underway.

This Research Topic aims at presenting the latest scientific advances in the area of the design and construction of novel photocatalysts from fundamental chemistry/mechanism of materials synthesis. This Research Topic seeks high-quality works which feature the latest advancements in photocatalysts, including the development of novel and advanced photocatalysts, advanced applications, and in-depth understanding of photocatalysis mechanisms.
