The synthesis of high-performance catalysts for volatile organic compounds (VOCs) degradation under humid conditions is essential their practical industrial application. Herein, a codoping strategy was adopted to synthesize the N-Co3O4-C catalyst with N, C low-temperature ethyl acetate (EA) conditions. Results showed that exhibited great catalytic activity (T 90 = 177 °C) and water resistance (5.0 vol% H2O, T 178 EA degradation. Characterization results suggested C, N weakened Co-O bond strength, increased surface Co3+ Oads species, improved redox ability mobility lattice oxygen which boosted performance Meanwhile, N-doping-induced vacancies could interact vapor generate extra active enhanced resistance. Importantly, based on series characterization technologies, in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), theoretical calculations, synergistic effect systematically investigated elucidated. doping induced increase area weakening adsorption species activation dissociate oxidize EA, forming key intermediate, acid. gaseous form attacking breaking C-C acid accelerate deep oxidation, synergistically facilitated

Homogeneously Distributed Heterostructure Energizes and Replenishes Oxygen Species for Boosting Toluene Oxidation on Perovskite Oxide Catalysts

Enriching oxygen species in perovskite catalysts provides more active sites for the catalytic oxidation of air pollutants, but its further application environmental chemical engineering is still constrained by inherent lack reactivity and difficulty replenishing depleted species. Herein, we present a scalable one-pot strategy situ fabrication homogeneously distributed heterostructure, which brings La2CuO4 58-fold activity enhancement robust antisintering/water/coke toluene oxidation, higher than currently reported catalysts. Superior to single "oxygen enrichment" effect conventional surface-aggregated heterostructures, heterostructures induce adsorbed backfilling/replenishment lattice oxygen, break through rate-determining steps low-temperature Langmuir-Hinshelwood high-temperature Mars-van Krevelen mechanisms, respectively. The scalability has been demonstrated broader systems evolution reaction, offering dependable supply catalysis.
