While the rapid development of society has brought material civilization to human beings, environmental pollution has become increasingly serious, especially in recent years, gaseous pollutants produced by human activities have seriously threatened the environment and human health.SSSSHowever, the successive discharge of gaseous pollutants into the atmosphere makes it necessary to develop suitable technologies to clean the air.SSBenzene volatile organic compounds (benzene VOCs) is one of the common gaseous pollutants in indoor air, which should be transformed into non-hazardous compounds through physical adsorption.SSPhotocatalytic oxidation (PCO) can effectively degrade benzene VOCs by generating highly active substances on the surface of the photocatalyst using the energy of photons under the action of light, without secondary pollution.SSAt present, many photocatalytic systems with different structures and physical and chemical properties have been applied to degrade benzene VOCs. In this paper, the basic principle of photocatalytic degradation of benzene VOCs, factors affecting the photocatalytic reaction and methods to improve the degradation efficiency have been systematically analyzed.SSThe design concept of all kinds of nanocatalizers and their performance in photocatalytic degradation of benzene VOCs were reviewed, and the future design of nanocatalizers was prospected.
