Summary: Raw materials and synthesis strategies significantly affect the morphology and optical properties of materials. In this study, controllable thin sheet-like BiPO4 with high visible-light response was synthesized using Bi-based metal-organic frameworks (CAU-17) and ionic liquid [Omim]H2PO4 as raw materials. The synthesized BiPO4-A and BiPO4-U showed better visible-light absorption capacity and narrower band gap compared to BiPO4-H synthesized using inorganic salt. The improved photocatalytic performance of the materials was attributed to fast charge transfer, large specific surface areas, and enhanced light adsorption. This study provides a new technique for synthesizing efficient photocatalysts for wastewater purification under visible-light.

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.
