Increasing demand for energy and environmental degradation are the most serious problems facing man. An interesting issue that can contribute to solving these is use of photocatalysis. According literature, solar in presence a photocatalyst effectively (i) be converted into electricity/fuel, (ii) break down chemical microbial pollutants, (iii) help water purification. Therefore, search new, efficient, stable photocatalysts with high application potential point great interest. The must characterized by ability absorb radiation from wide spectral range light, appropriate position semiconductor bands relation redox reaction potentials, long diffusion path charge carriers, besides thermodynamic, electrochemical, photoelectrochemical stabilities. Meeting requirements semiconductors very difficult. efforts being made increase efficiency photo processes changing electron structure, surface morphology, crystal structure semiconductors.

Mechanistic Understanding in Manipulating Energetics of TiO₂ for Photocatalysis

The Journal of Physical Chemistry C, Journal Year: 2023, Volume and Issue: 127(23), P. 10897 - 10912

Published: June 6, 2023

Titanium dioxide (TiO2) is a wide bandgap semiconductor that has range of applications including wastewater treatment, photocatalysis, solar cells, and sensors owing to its excellent electronic optical properties. However, the TiO2 (∼3.2 eV) along with recombination processes photoexcited charge carriers reduce interfacial transport properties respective activities. Energetics, response, corresponding photophysics excited can be altered through doping codoping composite formulation. Therefore, it very crucial understand structure–property property-application relationships doped, co-doped, maximize efficiency extend fundamental understanding for their in different fields. In this Perspective, we summarize ongoing research on advancement undoped, structure morphology, energetics, relative water-splitting reactions. We then propose our perspectives future potential energetic manipulation photocatalytic develop advanced highly efficacious catalytic materials.
