- Visible-light-driven photocatalysts are essential for efficient solar energy utilization.
Purpose of the Study:
- To summarize rutile TiO2-based photocatalysts for water-splitting systems.
- To highlight the role of rutile TiO2 in Z-scheme water splitting.
- To discuss strategies for enhancing photocatalyst efficiency.
Main Methods:
- Review of literature on rutile TiO2 photocatalysts.
- Analysis of doping strategies for visible-light activity.
- Discussion of charge balance in doped rutile TiO2.
Main Results:
