Summary: In this study, a photocatalytic textile was prepared by spraying heterostructures of oxygen vacancies (OVs)-rich bismuth oxide (BiO2-x) and urea-derived graphitic carbon nitride (UCN) on a modified poly(acrylonitrile) nonwoven textile (APAN). The photocatalytic textile showed excellent activity for sulfamethazine (SMT) removal and bacterial disinfection under white light emitting diodes (LEDs) irradiation. The enhanced photocatalytic performance was attributed to the formation of oxygen vacancies and heterostructures.

Summary: A series of 2D BA2MAn-1PbnBr3n+1 perovskite nanosheets were synthesized via a facile, ligand-free precipitation method. The 2D perovskite nanosheets were found to effectively generate photosensitized singlet oxygen (1O2) through energy transfer from triplet excitons to molecular oxygen. The as-prepared BA2PbBr4 and BA2MAPb2Br7 nanosheets successfully catalyzed the ENE reaction and 1,2-addition reaction between olefin and singlet oxygen. This study is expected to develop and demonstrate new mechanisms for 2D halide perovskite materials in photodynamic therapy and photocatalytic applications.

Summary: This study demonstrates the use of iron sites immobilized on defective BiOBr nanosheets as an efficient and selective photocatalyst for the activation of O2 to O1(2), achieving high conversion rates and selectivity in various organic oxidation reactions. The Fe3+ species anchored by oxygen vacancies facilitate charge separation and migration, promote effective adsorption of O2, and boost the quantum yield of excited triplet state, leading to enhanced photocatalytic performance. This work highlights the important role of metal sites anchored on semiconductors in regulating charge/energy transfer during heterogeneous photocatalysis and provides a new approach for designing high-performance photocatalysts.

Summary: The selective control of reactive oxygen species (ROS) is crucial in abating aquatic organic pollutants in advanced oxidation processes (AOPs). Copper phosphide (CuxP) exhibits a Janus-like behavior, serving as a solid oxidative reagent under acidic and dark conditions and as a photosensitizer under neutral and light conditions. This dual nature of CuxP allows for the selective production of ROS and offers new possibilities for water treatment and the development of efficient AOP systems.

Summary: This study investigated a surfactant-capping strategy to enhance the photocatalytic performance of rhodamine B (RhB) on one-dimensional rod-like Bi2S3 nanocrystals. It was found that polyvinylpyrrolidone (PVP)-capped Bi2S3 (Bi2S3-PVP) exhibited a higher RhB degradation rate compared to pure Bi2S3, and further studies suggested enhanced reaction interface compatibility at the Bi2S3-PVP-RhB interface. This research provides an interface microenvironment modulation strategy for improving the photocatalytic performance towards organic dyes.

Summary: In this study, a new lead-free perovskite solid solution Cs-3(BixSb1-x)(2)Br-9 with tunable band gap was prepared through a facile and efficient co-precipitation method. The introduction of Sb atoms in Cs3Bi2Br9 significantly broadened the absorption of visible light, making it a promising visible-light photocatalyst. The CBSB solid solution also exhibited excellent stability, showing no apparent decrease in catalytic activity in a five-cycle experiment. This research provides new insights into improving the carrier lifetime of lead-free perovskite materials, presents a new approach for selective photo-oxidation, and may have implications for other solar energy conversion areas related to halide perovskites.

Summary: In recent years, two-dimensional and quasi-2D Ruddlesden-Popper perovskite materials have been developed as emerging semiconductor materials for solar cells due to their structural diversity and high power-conversion efficiency. However, their photocatalytic applications have been rarely explored. In this study, a 2D/quasi-2D RP perovskite was fabricated and used as a photocatalyst for hydrohalic acid splitting. The results showed that the stress in the perovskite significantly influenced its photoelectronic properties, and the quasi-2D perovskite with a high n value exhibited the highest photocatalytic activity, attributed to its efficient charge transport and separation capability.

Summary: Alpha-Fe2O3 is a promising photocatalytic material with low cost and excellent visible light absorption, but its efficiency is limited by charge recombination. This study introduces Ga in the form of Fe2-xGaxO3 solid solution to improve the electronic structure and photoelectrical activity. The introduction of Ga reverses the electron spin state, suppressing carrier recombination. Experimental results support the theoretical calculations, and Fe1.96Ga0.04O3 shows the best photothermal activity for CO2 reduction, with a CO evolution rate 2.4 times higher than pure Fe2O3. This work provides an alternative approach to enhance the activity of alpha-Fe2O3.

Summary: Metal nitrides are usually prepared by high temperature nitridation with metal oxide precursors under an NH3 atmosphere. However, the preparation of oriented nitride nanostructures is challenging due to the differences in crystal structures between oxide precursors and nitride products. This work systematically investigates the endotaxial growth process of TaON from a LiTaO3 single crystal substrate and proposes a plausible growth mechanism. It contributes to a better understanding of the unique endotaxial growth process and facilitates the fabrication of other oriented nitride nanostructures.
