多相光催化氧化是环境净化领域中最活跃的研究领域之一。最近，基于PCO技术的空气净化器和建筑材料的研究已经被集中进行用于室内/室外空气处理。该创新技术致力于在紫外线或太阳光的照射下使用光催化剂分解气态污染物，而无需额外添加能量。已经建立了使用间歇式反应器或连续式反应器处理空气的PCO的性质和性能的全面知识。本文综述了PCO技术在空气净化领域的最新进展及其应用前景。首先，介绍了PCO的基本原理，包括传质、吸附和表面反应，为研究结果提供了合理的解释。其次，在各种规模的实验工作和其他相关的研究，如建模方法，涂层技术，和测试方法，分别为PCO空气净化器和建筑材料进行了讨论和评价。在此基础上，从两个方面详细阐述了相关的技术问题和未来的研究方向。(C)2015爱思唯尔有限公司版权所有。
Heterogeneous photocatalytic oxidation (PCO) is one of the most active research areas in environmental purification. Recently, research on PCO technologies-based air cleaners and building materials has been intensively conducted for indoor/outdoor air treatment. The innovative technology is dedicated to decompose gaseous pollutants using photocatalysts under illumination of UV or solar light without extra energy added. Comprehensive knowledge on the properties and performance of PCO for treatment of air using batch reactors or continuous reactors has been established. This critical review has been carried out with aims to examine the state-of-the-art of PCO technologies in the field of air purification and their application prospects. First, PCO fundamental principles, including mass transfer, adsorption, and surface reaction, are reviewed, providing rational explanations for research results. Second, the experimental work in various scales and other related research, such as modeling methods, coating techniques, and testing methods, are discussed and evaluated separately for PCO air cleaners and building materials. Based on these insights, the corresponding technological problems and future research directions for promotion of commercial applications in two aspects are also described in detail.
