Oxygen vacancy enhanced visible light photocatalytic selective oxidation of benzylamine over ultrathin Pd/BiOCl nanosheets

Shuai Wei et al.

Summary: Two atomic layered BiOCl nanosheets with rich oxygen vacancies were constructed via surface Pd deposition, exhibiting high photocatalytic activity and selectivity. The ultrathin structure of the nanosheets induces the formation of surface oxygen vacancies, resulting in increased visible light absorption. In-situ experiments revealed that the oxygen vacancy sites contribute to the conversion of O-2 molecules from air to the surface. Furthermore, low-coordinated Bi and Pd sites play crucial roles in the formation of active species.

WO3-based photocatalysts: A review on synthesis, performance enhancement and photocatalytic memory for environmental applications

Ojo Samuel et al.

Summary: Traditional photocatalysts like titanium dioxide have the limitation of not being able to absorb visible light, making it necessary to find new photocatalysts that can overcome this issue. Tungsten oxide and its composites have gained popularity in recent years due to their smaller band gap energy, but pristine tungsten oxide has limitations in energy density and specific surface area. Developing various materials based on tungsten oxide can improve its performance.

Discovering the key role of MnO2 and CeO2 particles in the Fe2O3 catalysts for enhancing the catalytic oxidation of VOC: Synergistic effect of the lattice oxygen species and surface-adsorbed oxygen

Wissem Ben Soltan et al.

Summary: Highly active mesoporous Fe-Mn-Ce catalysts with high specific surface area were synthesized by a modified precipitation process. The catalysts exhibited rich surface oxygen species, higher proportions of Mn4+ and Ce4+, higher concentration of lattice defects and oxygen vacancies, and superior low-temperature redox property. These properties contributed to high catalytic activity and efficient toluene conversion at lower temperatures.

Efficient photocatalytic epoxidation of styrene over a quantum-sized SnO2 on carbon nitride as a heterostructured catalyst

Min Li et al.

Summary: In this study, a quantum-sized SnO2 on 2D graphitic carbon nitride was synthesized as a heterostructured catalyst for efficient photocatalytic styrene epoxidation at room temperature using O-2 as an oxidant. Photoelectrochemical analysis showed efficient electron transfer and enhanced charge carriers' separation and transfer processes. Furthermore, the photocatalytic styrene epoxidation was coupled with epoxide ring-opening amination, achieving the synthesis of valuable chemicals in a cascade reaction fashion.

Local surface plasma resonance effect enhanced Z-scheme ZnO/Au/g-C3N4 film photocatalyst for reduction of CO2 to CO

Xin Li et al.

Summary: The Z-scheme ZnO/Au/g-C3N4 micro-needle film enhanced by the Local Surface Plasma Resonance (LSPR) effect demonstrated excellent photocatalytic performance and reusability in the photoreduction of CO2 into CO under UV-vis light irradiation. The material achieved a high CO production rate after 8 hours of reaction time, which was significantly higher than that of the pure ZnO film. The combination of factors such as the electric field at the g-C3N4/ZnO interface, the role of Au NPs as electron-transfer bridges and LSPR excited sources, and in-situ FTIR technique investigation contribute to the enhanced electron transfer efficiency and overall photocatalytic performance.

Tong Liu et al.

Summary: Researchers constructed a MoSe2/WO3(001) heterojunction (MWH) and used density functional theory (DFT) to calculate and analyze its electronic structure and optical properties to reveal its photocatalytic mechanism. The MWH exhibited Z-scheme photocatalytic heterojunction characteristics, successfully inhibiting the recombination of photogenerated carriers through the segregation of oxidation and reduction sites.

Selective photocatalytic reduction CO2 to CH4 on ultrathin TiO2 nanosheet via coordination activation

Zhi-Wen Wang et al.

Summary: Ultra-thin TiO2 nanosheet (NST) with abundant Ti3+ sites has been developed as a photocatalyst for high yield and selectivity in the conversion of CO2 to CH4. The NST selectively activates CO2 on its surface, forming bridging Ti dot CO2-Ti coordination species to lower the activation energy barrier and determine the selectivity for CH4 production via Ti-C coordination bond.
