Nanoporous silica solids can offer opportunities for hosting photocatalytic components such as various tetra‐coordinated transition metal ions to form systems referred to as “single‐site photocatalysts”. Under UV/visible‐light irradiation, they form charge transfer excited states, which exhibit a localized charge separation and thus behave differently from those of bulk semiconductor photocatalysts exemplified by TiO₂. This account presents an overview of the design of advanced functional materials based on the unique photo‐excited mechanisms of single‐site photocatalysts. Firstly, the incorporation of single‐site photocatalysts within transparent porous silica films will be introduced, which exhibit not only unique photocatalytic properties, but also high surface hydrophilicity with self‐cleaning and antifogging applications. Secondary, photo‐assisted deposition (PAD) of metal precursors on single‐site photocatalysts opens up a new route to prepare nanoparticles. Thirdly, visible light sensitive photocatalysts with single and/or binary oxides moieties can be prepared so as to use solar light, the ideal energy source.

使用纳米多孔单站点光催化剂设计高级功能材料

纳米多孔二氧化硅固体可以为承载光催化组分（例如各种四配位过渡金属离子）形成称为“单部位光催化剂”的系统提供机会。在紫外线/可见光照射下，它们形成电荷转移激发态，表现出局部电荷分离，因此其行为与以TiO ₂为例的块状半导体光催化剂不同。此帐户概述了基于单中心光催化剂独特的光激发机理的高级功能材料设计。首先，将介绍在透明多孔二氧化硅膜中引入单中心光催化剂的方法，该膜不仅具有独特的光催化性能，而且还具有自清洁和防雾应用的高表面亲水性。金属前体在单中心光催化剂上的二次光辅助沉积（PAD）开辟了制备纳米颗粒的新途径。第三，可以制备具有单和/或二元氧化物部分的可见光敏感的光催化剂，以便使用理想的能源太阳光。
