Abstract

Visible-light-driven photocatalysis has great potential in environmental remediation and organic synthesis. Rational design and regulation of the reaction interfacial microenvironment is critical for photocatalytic performance, yet challenging. We report here a highly efficient photocatalytic system based on hydrophobic TiO₂ porous (H-OTP) film for visible-light-driven dye-sensitized photo-oxidation. Such interface architecture design enhances the adsorption capability of organic dyes and enables the formation of air trapped triphase reaction interface microenvironment as confirmed via three-dimensional (3D) laser scanning confocal microscopy. Based on this interface architecture, the concentrations of O₂ and organic molecule at the local reaction zone are both significantly increased, which promotes the generation of reactive oxygen species (•O₂⁻ and •OH), and enhances the photocatalytic performance in terms of both kinetics and organic mineralization efficiency. This study highlights the importance of interface microenvironment design and reveals an effective way to develop highly efficient photocatalytic systems.

基于有序TiO2多孔膜的界面微环境工程用于增强可见光驱动光催化

可见光驱动光催化在环境修复和有机合成方面具有很大的潜力。合理设计和调节反应界面微环境对光催化性能至关重要，但也具有挑战性。本文报道了一种基于疏水TiO2多孔（H-OTP）薄膜的可见光驱动染料敏化光氧化的高效光催化体系。这种界面结构设计增强了有机染料的吸附能力，并通过三维激光扫描共聚焦显微镜证实了气阻三相反应界面微环境的形成。基于这种界面结构，局部反应区O2和有机分子浓度均显著增加，促进了活性氧（•O2−和•OH）的生成，从动力学和有机矿化效率两方面提高了光催化性能。本研究强调了界面微环境设计的重要性，揭示了开发高效光催化系统的有效途径。
