This article reviews two interrelated areas of research: the first is the use of TiO-supported adsorbent materials as enhanced heterogeneous photocatalysts and their application to various reactions for organic pollutant removal from air and water; the second is the combination of adsorbent materials with TiO photocatalysts which aims to efficiently regenerate adsorbent materials using illumination. By reviewing both areas of research, the following topics are covered; (i) photocatalytic activation of TiO (ii) related properties of photocatalytic TiO (iii) shortcomings of photocatalytic processes; (iv) preparation methods of composite TiO/adsorbent materials and their photocatalytic performance; (v) properties of common adsorbents and their applications for pollutant removal from air and water; (vi) adsorbent regeneration methods and their economic and operational issues; (vii) conclusions and future outlooks. This topic has not been previously reviewed to such an extent, and considerable knowledge can be gained from assembling the large number of studies on adsorption-photocatalysis combinations. As such, this review provides guidance for researchers working in the fields of environmental and chemical engineering focussing on organic pollutant removal and the engineering of new high performance photocatalytic TiO-supported porous adsorbent materials.
第一是将 TiO 负载吸附材料作为增强型非均相光催化剂，及其在各种反应中用于去除空气和水中的有机污染物；第二是将吸附材料与 TiO 光催化剂结合，旨在通过光照有效再生吸附材料。通过综述这两个研究领域，涵盖了以下主题：(i) TiO 的光催化活化；(ii) 光催化 TiO 的相关性质；(iii) 光催化过程的缺点；(iv) 复合 TiO/吸附材料的制备方法及其光催化性能；(v) 常见吸附剂的性质及其在空气和水中污染物去除中的应用；(vi) 吸附剂再生方法及其经济和操作问题；(vii) 结论和未来展望。这个主题以前没有被如此广泛地综述过，从大量关于吸附-光催化组合的研究中可以获得相当多的知识。因此，本综述为从事环境和化学工程领域研究的人员提供了指导，重点是去除有机污染物和工程新型高性能 TiO 负载多孔吸附材料。
