“环境催化城市”:概念提出和研究展望

“Environmental Catalytic City”:Concept and Research Prospects

大气污染是城市环境质量改善面临的重大挑战。城市化过程既是造成城市大气高度复合污染的重要原因,也为城市自净化大气污染物提供了可人为强化的条件。“环境催化城市”是指将城市中的建筑物内外、硬化地面等表面涂覆催化材料,在自然界的光、热等条件下实现环境中低浓度气态污染物自发催化净化的城市。构建“环境催化城市”对低碳控制大气复合污染,持续改善室内外环境空气质量,规划建设“自净城市”意义重大。本文提出了“环境催化城市”概念,并对如何完善和发展“环境催化城市”理论和实践进行了展望。

Air pollution is a major challenge for the improvement of urban environmental quality.The process of urbanization is an important cause of highly complex air pollution.On the other hand,it also provides artificial reinforcement conditions for self-purification of air pollutants in cities.“Environmental catalytic city”refers to the spontaneous catalytic purification of low-concentration gaseous pollutants in the atmosphere by catalytic materials coating on artificial surfaces,such as building surfaces in the city,under natural photothermal conditions.“Environmental catalytic city”is of great significance for the control of complex air pollution without additional energy consumption,the continuous improvement of indoor and outdoor air quality,and the scheme and construction of a“self-purifying city”.Here,we propose the concept of an“environmental catalytic city”,and discuss its further improvement,development,and application.
