Renewable and sustainable energy source is highly desirable for solving the serious environmental pollution and energy shortage problems. In this regard, photocatalysis has attracted worldwide attention due to its potential in solar energy conversion. By using an efficient photocatalyst, sunlight can be converted to chemical energy to achieve a wide range of environmental and energy applications, such as hydrogen evolution by water splitting, CO₂ conversion to hydrocarbon fuels, photocatalytic pollutants degradation, and water disinfection.

We invite investigators to contribute original research articles as well as review articles that will stimulate the continuing efforts to the development of high-efficient photocatalysts, the understanding of photocatalytic mechanisms, and the advanced technology that may bring photocatalysis into practical application. We are interested in articles that explore both fundamental and applied aspects of photocatalysis in environmental remediation and sustainable energy supply.

Potential topics include, but are not limited to:

• Recent developments in TiO₂-based photocatalysis
• Novel photocatalytic materials, including metal-free photocatalysts (i.e., g-C₃N₄) and plasmonic photocatalysts
• Novel synthetic methodology for the preparation of nanostructured photocatalysts
• Recent developments in photocatalytic water splitting, CO₂ reduction, organic pollutants degradation, water disinfection, and selectively organic synthesis
• Photocatalytic kinetics and mechanisms study
• Advances in photocatalytic reactor design and catalyst immobilization
