Molybdenum Sulfide (MoS(2))/Ordered Mesoporous Carbon (OMC) Tubular Mesochannel Photocatalyst for Enhanced Photocatalytic Oxidation for Removal of Volatile Organic Compounds (VOCs)

Air pollutants cause severe problems in urban areas, specifically in terms of toxicological impacts on human health. Therefore, it is urgent to develop an effective, safe, and inexpensive technique to remove these air pollutants. In this study, the MoS(2)/OMC heterojunction photocatalyst was success...

description Air pollutants cause severe problems in urban areas, specifically in terms of toxicological impacts on human health. Therefore, it is urgent to develop an effective, safe, and inexpensive technique to remove these air pollutants. In this study, the MoS(2)/OMC heterojunction photocatalyst was successfully synthesized by a hydrothermal process and used for improving photocatalytic oxidation performance for removing VOCs. Formaldehyde was used as a model VOC in the gas phase and was removed at room temperature under visible light irradiation. For my research, the microstructure and morphology of the photocatalyst were deeply characterized, and the results indicated that MoS(2) were successfully coupled into OMC materials to prepare MoS(2)/OMC heterojunction photocatalysts. The trend of photocatalytic efficiency for formaldehyde decomposition was MoS(2)/OMC > MoS(2) > OMC. Besides, the MoS(2)/OMC heterojunction photocatalyst showed an excellent regeneration performance after several recycles, indicating the potential of MoS(2)/OMC composite as a promising photocatalyst for VOC removal. These results indicated that the photocatalytic reactor containing MoS(2)/OMC photocatalysts was highly active and stable.
