Abstrakt: Over the last decade, interest in the utilization of solar energy for photocatalysis treatment processes has taken centre-stage. Researchers had focused on doping TiO 2 with SiO 2 to obtain an efficient degradation rate of various types of target pollutants both under UV and visible-light irradiation. In order to further improve this degradation effect, some researchers resorted to incorporate plasmonic metal nanoparticles such as silver and gold into the combined TiO 2 -SiO 2 to fully optimize the TiO 2 -SiO 2 's potential in the visible-light region. This article focuses on the challenges in utilizing TiO 2 in the visible-light region, the contribution of SiO 2 in enhancing photocatalytic activities of the TiO 2 -SiO 2 photocatalyst, and the ability of plasmonic metal nanoparticles (Ag and Au) to edge the TiO 2 -SiO 2 photocatalyst toward an efficient solar photocatalyst.
Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.
