Active site-directed tandem catalysis on CuO/VO-MnO2 for efficient and stable catalytic ozonation of S-VOCs under mild condition

Recent progresses in the synthesis of MnO2 nanowire and its application in environmental catalysis

“…Additionally, the catalyst retained long-term stability and could be facilely regenerated to its initial activity with ethanol and HCl. Yang et al 189 synthesized urchin-like oxygen vacancy-rich (V O ) hollow-structured MnO 2 with the loading of CuO nanoparticles on the surface (CuO/V O -MnO 2 ). The well-dispersed CuO on the surface of urchin-like hollow MnO 2 enhanced the chemisorption of CH 3 SH, thus promoting the efficient decomposition of CH 3 SH on the CuO/V O -MnO 2 .…”

“…Air humidity is an important physical factor that influences photocatalytic air purification. 30 In most cases, water vapor is one of the major obstacles that inhibits photocatalytic NO removal. 31 Here, the humidity effects on the photocatalytic NO removal by the CsPbBr 3 NC catalyst were investigated in humid air (Figure 3c).…”

Enhanced Catalytic Ozonation for Eliminating CH3SH via Graphene-Supported Positively Charged Atomic Pt Undergoing Pt2+/Pt4+ Redox Cycle

“…As one of the main contributors to malodorous pollution, the elimination of sulfur-containing volatile organic compounds (SVOCs) like methyl mercaptan (CH 3 SH) has attracted increasing public attention. 1,2 With the concentrations ranging from tens to hundreds of ppm, CH 3 SH with an ultralow olfactory threshold exists widely in the petroleum industry, sewage/waste water treatment plants, and sanitary landfill. 3−5 High concentrations of CH 3 SH can poison the human nervous system, cause acid rain, corrode reactors, and inactivate catalysts in chemical industry.…”

“…As one of the main contributors to malodorous pollution, the elimination of sulfur-containing volatile organic compounds (SVOCs) like methyl mercaptan (CH 3 SH) has attracted increasing public attention. , With the concentrations ranging from tens to hundreds of ppm, CH 3 SH with an ultralow olfactory threshold exists widely in the petroleum industry, sewage/waste water treatment plants, and sanitary landfill. − High concentrations of CH 3 SH can poison the human nervous system, cause acid rain, corrode reactors, and inactivate catalysts in chemical industry. , Hence, numerous techniques have been investigated to remove CH 3 SH such as adsorption, , biological degradation, catalytic oxidation, photocatalytic oxidation, , and catalytic ozonation . Especially, catalytic ozonation is an effective and economic technology for the removal of SVOCs owing to its high efficiency, enhanced mineralization, and mild operation conditions. , To achieve the efficient and complete SVOCs removal, it is necessary to develop highly active catalysts for catalytic ozonation to eliminate CH 3 SH.…”
