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 with SiO 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-SiO to fully optimize the TiO-SiO's potential in the visible-light region. This article focuses on the challenges in utilizing TiO in the visible-light region, the contribution of SiO in enhancing photocatalytic activities of the TiO-SiO photocatalyst, and the ability of plasmonic metal nanoparticles (Ag and Au) to edge the TiO-SiO photocatalyst toward an efficient solar photocatalyst.
在过去十年中，利用太阳能进行光催化处理过程的研究备受关注。研究人员致力于通过用二氧化硅（SiO）掺杂二氧化钛（TiO），以在紫外光和可见光照射下实现对各类目标污染物的高效降解率。为了进一步提高这种降解效果，一些研究人员将银和金等等离子体金属纳米颗粒引入TiO-SiO复合材料中，以充分优化TiO-SiO在可见光区域的潜力。本文重点探讨了TiO在可见光区域应用中的挑战、SiO对提高TiO-SiO光催化剂光催化活性的贡献，以及等离子体金属纳米颗粒（Ag和Au）促使TiO-SiO光催化剂成为高效太阳能光催化剂的能力。
