Mesoporous nanocrystalline metal oxides such as TiO₂, SnO₂, and TiO₂-SnO₂ composites form a new class of mesoporous inorganic solids, which exhibit excellent structural, textural, optical, and photocatalytic properties. Furthermore, they also possess a large number of surface-exposed catalytic active sites in addition to their intrinsic flexible diffusion characteristics. In this investigation, we report the photocatalytic activity of high-quality mesoporous TiO₂, SnO₂, and TiO₂-SnO₂ composites. All the catalysts were tested for photocatalytic degradation of 4-chlorophenol under a solar simulator. The reaction results indicate that the anatase-phase mesoporous Ti_0·9Sn_0·1O₂ exhibits enhanced activity as compared with the commercial TiO₂ (P-25).

介孔纳米晶体金属氧化物（例如TiO ₂，SnO ₂和TiO ₂ -SnO ₂复合材料）形成一类新型的介孔无机固体，具有出色的结构，结构，光学和光催化性能。此外，它们除了具有固有的挠性扩散特性外，还具有大量表面暴露的催化活性位。在这项研究中，我们报告了高质量的中孔TiO ₂，SnO ₂和TiO ₂ -SnO ₂的光催化活性。复合材料。在太阳模拟器下测试所有催化剂对4-氯苯酚的光催化降解。反应结果表明，与商业TiO ₂（P-25）相比，锐钛矿相的介孔Ti _0·9 Sn _0·1 O ₂具有增强的活性。
