Research Progress on Generation Mechanism and Detection Methods of Reactive Oxygen Species During Photocatalytic Reaction Based on TiO₂

摘要: 活性氧物种（Reactive Oxygen Specie，ROS）在光催化反应中起着非常重要的作用.以二氧化钛（TiO₂）为例，利用49篇文献简要综述了其在光催化反应过程中几种典型ROS，如：超氧自由基（·O₂^-）、羟基自由基（·OH）、单线态氧（¹O₂）和过氧化氢（H₂O₂）的产生过程，列举了ROS的一般检测方法，对ROS在光催化反应研究中存在的问题和发展趋势给出了建议和展望.

Abstract: Reactive oxygen species (ROS) play a very important role in photocatalytic reactions. Titanium dioxide (TiO₂) is chosen as an example to briefly overview the production process of several typical ROS such as superoxide radical (·O₂^-), hydroxyl radical (·OH), singlet oxygen (¹O₂) and hydrogen peroxide (H₂O₂) during its photocatalytic reaction. The general detection methods of ROS are introduced in detail, and suggestions and prospects are given for the problems and development trends of ROS in the research of photocatalytic reactions.
