In recent years, the application of heterogeneous photocatalytic water purification processes has gained wide attention due to its effectiveness in degrading and mineralizing the recalcitrant organic compounds as well as the possibility of utilizing the solar UV and visible-light spectrum. By far, titania has played a much larger role in this scenario compared to other semiconductor photocatalysts due to its costly effectiveness, inert nature and photostability. A substantial amount of research has focused on the enhancement of TiO(2) photocatalysis by modification with metal, non-metal and ion doping. This paper aims to review and summarize the recent works on the titanium dioxide (TiO(2)) photocatalytic oxidation of phenol and discusses various mechanisms of phenol photodegradation (indicating the intermediates products) and formation of OH radicals. Phenol degradation pathway in both systems, TiO(2)/UV and doped-TiO(2)/Vis, are described.
近年来，由于异质光催化水净化工艺能够有效降解和矿化难降解有机化合物，并且能够利用太阳紫外线和可见光光谱，因此得到了广泛的关注。到目前为止，与其他半导体光催化剂相比，由于其高效、惰性和光稳定性，二氧化钛在这一领域发挥了更大的作用。大量研究集中在通过金属、非金属和离子掺杂来增强 TiO(2)光催化作用。本文旨在综述和总结近年来关于 TiO(2)光催化氧化苯酚的研究工作，并讨论苯酚光降解的各种机制（表明中间产物）和 OH 自由基的形成。描述了 TiO(2)/UV 和掺杂-TiO(2)/Vis 两种体系中苯酚的降解途径。
