Water vapor is a significant component in real volatile organic compounds (VOCs) exhaust gas and has considerable impact on the catalytic performance of catalysts for VOC oxidation. Important progress been made reaction mechanisms H2O water resistance strategies oxidation recent years. Despite advancements technology, most still exhibit low activity under humid conditions, presenting challenge reducing adverse effects To develop water-resistant catalysts, understanding mechanistic role implementing effective water-resistance with influencing factors are imperative. This Perspective systematically summarizes related research oxidation, drawing from over 390 papers published between 2013 2024. Five main proposed to clarify their H2O. inhibition/promotion introduced, elucidating various VOCs. Additionally, different kinds discussed, including fabrication hydrophobic materials, design specific structures morphologies, introduction additional elements catalyst modification. Finally, scientific challenges opportunities enhancing efficient practical applications purification highlighted.

In contrast to numerous studies on oxygen species, the interaction of volatile organic compounds (VOCs) with oxides is also critical catalytic reaction but has hardly been considered. Herein, we develop a highly efficient Pt atom doped spinel CoMn2O4 (Pt-CoMn) for oxidation toluene at low temperature, and conversion rate increased by 18.3 times (129.7 versus 7.1 × 10–11 mol/(m2·s)) 160 °C compared that CoMn2O4. Detailed characterizations density functional theory calculations reveal local electron environment Co sites changed after doping, formed electron-deficient in turn strengthen toluene. Adsorbed will react lattice Pt-CoMn CoMn catalysts convert into benzoate intermediates, consumption closely related activation gaseous oxygen. Significantly, abundant bulk defects help open channel spinel, which acts as an pump promote transformation surface lower temperatures, thus accelerating intermediates CO2 enhancing low-temperature combustion developed here emphasizes regulation VOCs adsorption strength processes adjusting environment, provide new guidance design oxide oxidation.
