Development of Visible Light-Responsive Photocatalysts
Description
Photocatalysis has received considerable attention because of its promising applications such as in photocatalytic degradation of organic pollutants, photocatalytic dissociation of water, solar energy conversion, and disinfection. As an important semiconductor, photocatalytic materials, titania has been attracting the worldwide attention due to its good chemical stability, insolubility in water, and nontoxic, low cost, and readily available raw materials. However, the relatively high intrinsic band gap of titania can only be excited by a small UV fraction of solar light, which has practically ruled out the use of sunlight as an energy source. On the other hand, the photogenerated electrons and holes can recombine easily, inducing lower quantum efficiency. Both reasons mentioned above largely restricted their industrial applications. It has become a hot topic in photocatalysis scopes that how to expand the spectral response range and improve the photocatalysis quantum efficiency of photocatalysts.
We invite investigators to contribute original research articles as well as review articles that will stimulate the development of visible light-responsive photocatalysts and their applications in renewable energies and environmental protections. We are particularly interested in articles describing the new prepartion method of photocatalysts and modification of TiO2 and new photocatalytic mechanisms driven by visible light. Potential topics include, but are not limited to:
- Visible light photocatalytic mechanism
- Preparation of novel visible light-responsive photocatalysts
- Development of modified TiO2 photocatalysts
- Visible light-responsive photocatalysts by applying ion-engineering techniques
- Photocatalytic applications in environmental protections
- Photocatalytic water splitting using visible light-responsive photocatalysts
- Photocatalysts used in CO2 reduction
