Abstract
With the rapid development of industrialization and urbanization, the problem of environmental pollution is becoming more and more serious, which poses a great threat to human health and ecosystem. Firstly, the introduction introduces the research background and significance of photocatalysis technology, summarizes the research status at home and abroad in the field of photocatalysis, and clarifies the purpose of this study. Then, the second chapter describes the basic concepts of photocatalytic materials, including the principle of photocatalysis, material types and characteristics, as well as the historical development and current situation of photocatalytic materials. The third chapter discusses the application of photocatalytic materials in environmental governance in detail, including photocatalytic degradation of organic pollutants, purification of indoor air, degradation of persistent organic pollutants and application in water treatment. These applications demonstrate the important role of photocatalysis technology in reducing environmental pollution and improving environmental quality. Chapter 4 focuses on the application of photocatalytic materials in chemical engineering, including green chemical synthesis, energy conversion and storage, and the development of anticorrosive and self-cleaning materials. These applications show that photocatalysis technology has great potential to promote the sustainable development of the chemical industry and improve energy efficiency. In Chapter 5, the optimization and modification of photocatalytic materials are analyzed, including doping modification, composite modification, morphology control and surface modification, so as to improve the photocatalytic activity, stability and selectivity of photocatalytic materials. Chapter 6 evaluates the environmental and economic benefits of photocatalytic materials, including pollutant removal efficiency, environmental risk assessment, cost analysis, market potential analysis and return on investment analysis, in order to evaluate the economic feasibility and market prospects of photocatalytic technology. Finally, this paper summarizes the research results and looks forward to the future research direction. Through this study, we expect to provide theoretical basis and technical support for the application of photocatalytic technology in environmental governance and chemical engineering, promote the further development and industrialization of photocatalytic materials, and contribute to the realization of green sustainable development.
