摘要：
Emissions from various industries have led to increasingly serious environmental problems. Volatile organic compounds (VOCs) is the primary components of industrial waste gas, and photocatalytic advanced oxidation technology for non-selective oxidation of VOCs has attracted extensive researches. In order to solve the problem of low efficiency in the photocatalytic reaction, this review described the influencing factors of photocatalytic degradation of VOCs (temperature, relative humidity, initial gas concentration, oxygen concentration and gas flow rate), and summarized the influencing mechanism and influencing trend of various process parameters. With the continuous development of photochemical and electrochemical technologies, their combination has become a new research direction, and bias voltage can effectively reduce the recombination rate of electron hole pair. So, this review also summarized the influence of bias voltage in different photoelectric catalytic reactors on the photoelectric catalysis mechanism. Experimental research progress of photocatalysis/photoelectrocatalysis in recent five years were introduced, which has guiding significance for the design and optimization of the photocatalysis/ photoelectrocatalysis degradation of industrial waste gas VOCs. In the future, it will be the development trends to carry out experimental research with the parameters matching the industrial waste gas VOCs and to develop simple and efficient photocatalysis/photoelectrocatalysis reactor. © 2023 Chemical Industry Press.
