Summary: This study focuses on the ozone catalytic oxidation (OZCO) of alkanes at low temperatures (25-200 degrees C) using an alumina-supported manganese oxide catalyst, demonstrating that oxidation reactions can be accelerated in the presence of O-3. The superior catalytic performance of Mn/Al2O3 catalyst in OZCO is attributed to a high concentration of Mn2O3 species and oxygen vacancies, as indicated by characterization data (SEM-EDX, XRD, H-2-TPR, and XPS).

Summary: This study investigated the photocatalytic performance of f3-Bi203/Bi2O2CO3 composites, finding that the heterojunctions exhibited higher degradation efficiency and better separation efficiency under visible light irradiation. However, lower performance was observed under simulated sunlight, mainly due to the up-shift of the valence band position of Bi2O2CO3, leading to a decrease in oxidative ability of photo-induced holes.

Summary: Understanding the activity enhancement mechanism of VOC oxidation reaction is crucial for the development of efficient and cost-effective photothermocatalytic materials. In this study, porous and low-cost CeO2-MgO composite oxides were synthesized and applied for toluene photothermocatalytic oxidation. The optimized sample achieved a conversion rate of 90% for 1500 ppm toluene under the conditions of 330 degrees C and a gas hourly space velocity of 60,000 mL center dot g(-1)center dot h(-1). Gas phase oxygen and reactive oxygen species (ROS) were found to play a dominant role in the photothermocatalytic activity, while the contribution of photoinduced holes and surface lattice oxygen was 25%. In situ Fourier transform infrared and electron paramagnetic resonance results indicated that the synergistic photothermo activation of molecular oxygen accelerated the formation of low-temperature ROS.

Summary: Precise regulation of photogenic electron transfer pathway is crucial for enhancing photocatalytic carbon dioxide reduction efficiency and product selectivity. In this study, a g-C3N4/CoCo-layered double hydroxide (LDH) heterostructure was fabricated by designing the interface chemical bond Co-N-2 bond at the atomic level. This heterostructure realizes high-speed electron transport through the precise connection of valence band and conduction band using the interfacial Co-N-2 bond. Experimental results show that the addition of CoCo-LDH reduces the overpotential of water oxidation, regulates the charge delocalization of g-C3N4, and lowers the energy barrier of the CO2 intermediate in the reduction half-reaction. The selectivity of carbon-based substances in the products reaches 100%, with an optimal CO yield of 71.39 μmol g(-1) h(-1), which is among the highest values for g-C3N4-based photocatalysts.

Summary: Constructing heterostructured photocatalysts can enhance the separation efficiency of photocarriers, but the change in energy band positions affecting their redox ability has been overlooked. In this study, alpha-Bi2O3/Bi5NO3O7 heterojunctions were synthesized and characterized. The results showed that the heterojunctions had lower degradation ability due to the shift in energy bands, which decreased the oxidation ability of the holes and the activation ability of molecular oxygen.
