Abstract: Benzene volatile organic compounds (benzene VOCs) generally have long-lasting toxicity,
causing a series of sub health problems, such as genetic mutation, brain cancer, leukemia and other cancers.
Nano-photocatalysts have been widely used for benzene VOCs removal due to their characteristics of light
energy conversion and deep oxidation. Herein, the basic principles of photocatalytic degradation of benzene
VOCs were firstly briefly introduced, followed by discussions on the influence of internal and external
factors on the degradation activity of nanophotocatalysts based on their own physicochemical properties
and the environment located. Methods for improvement of degradation efficiency of photocatalysts were
then systematically analyzed, mainly from the aspects of light absorption enhancement, electron-hole
pairing inhibition and promote of surface charge participation in the reaction. Moreover, the recent research
progress in photocatalytic degradation of benzene VOCs was introduced in detail. Finally, the existing
problems of nano-photocatalysts were pointed out and the future development directions were prospected.
Key words: benzene volatile organic compounds; photocatalysts; photooxidation; degradation
