微塑料降解技术中半导体光催化剂的研究进展OA

Microplastic pollution is widespread in oceans,on land,and in the atmosphere,and has even entered organisms and the human body.As a novel pollutant,microplastics have posed a serious threat to both the environment and human health.Removing microplastic pollution holds significant importance for improving the ecological environment and promoting human societal development.The article introduces the sources and classification of microplastics,as well as photocatalytic techniques for removing microplastic pollutants,and provides an overview of the principles and applications of photocatalytic technology.It reviews the research progress in the photocatalytic degradation of microplastics using semiconductor catalysts such as titanium dioxide,zinc oxide,bismuth-based oxides,graphitic carbon nitride,and cadmium sulfide,and analyzes how the structure of catalysts affects pollutant degradation performance.The article proposes enhancing the degradation efficiency of microplastics by modulating catalyst structures,offering an environmentally friendly and feasible basis for mitigating the hazards of microplastics and addressing microplastic pollution.
