摘要
In this paper, research progress about the utilization of non-TiO2 photocatalysts in degradation of gaseous VOCs are reviewed. We give a concise overview of several novel non-TiO2 photocatalysts with a focus in their structure, which affect the catalytic activities, including metal oxide, wide bandgap p-block metal oxides/hydroxides, perovskite-type, spinel-type, bismuth based compounds, vanadium based compounds, et al. In addition, the research progress of influence factors of non-TiO2 photocatalytic purification of gaseous VOCs exhaust is summarized from photocatalytic reaction conditions (such as VOCs initial concentration, flow rate, light source, light intensity, reaction temperature and humidity). Finally, the fundamental challenges and perspectives of non-TiO2 photocatalysts are briefly brought up.
