Summary: In this study, sulfur-doped Bi-based metal-organic framework material CAU-17 was synthesized and applied for photocatalytic degradation of tetracycline. The optimized CAU-17-0.02 S sample exhibited enhanced photocatalytic performance with a removal efficiency of 62.9% and a degradation rate constant 1.44 times higher than that of bare CAU-17. Reactive species trapping experiment revealed that photogenerated holes, hydroxyl radicals, and superoxide anion radicals all contributed to the degradation of tetracycline, with the photogenerated holes playing the most significant role. Moreover, CAU-17-0.02 S showed good reusability with slight performance loss after four cycles.

Summary: Here, we presented the fabrication of well-crystalline metal-doped BiOCl nanoscale photocatalytic materials through solvothermal synthetic route. Ni doping significantly improved the photocatalytic and antibacterial behavior of BiOCl. The morphological study showed that different metal dopings led to the formation of nanosheet (Ni, Cd), nanoflower (Mo), and nanodisc (Co) morphologies, while Ni doping resulted in large size nanosheets with increased surface area and improved porous structure. The inclusion of Ni into BiOCl nanostructure shifted the band gap and reduced electron-hole recombination, contributing to its excellent photocatalytic performance. Additionally, Ni-BiOCl exhibited excellent photocatalytic antibacterial activity against S. aureus bacteria under visible light.

Summary: In this study, the luminescence properties of Ca2ZnSi2O7:Sm3+ phosphors were enhanced by co-doping with Bi3+/Al3+ via the sol-combustion method. The Bi3+/Al3+ co-doping did not change the tetragonal structure of Ca2ZnSi2O7, and resulted in significant enhancement of luminescence intensity. These co-doped phosphors show potential for application as red phosphors in white light emitting diodes.

Summary: By dual-ions (F and P) co-doping, the efficiency and stability of TiO2 in visible light absorption and photo-generated charge separation were significantly improved. FP3-TiO2 (001) exhibited excellent recycling and environmental stability, possibly due to the formation of Ti-IV-OOH and the continuous shift between it and its exited state.

Summary: A novel method using methylene blue as a photosensitizer for the homogeneous degradation of methyl orange under visible-light irradiation was proposed. The degradation mechanism involves Type II pathway and Type I photosensitization, and synchronous removal of methyl orange and methylene blue can be achieved by controlling the initial methylene blue concentration. This cost-effective method shows great potential in eliminating methyl orange and methylene blue from wastewater and offers a new strategy for sustainable water treatment.

Summary: Co-doped metal organic frameworks (MOFs) were fabricated using a facile method and applied for the removal of tetracycline, congo red, methylene blue, and rhodamine B through adsorption and photocatalysis. The assembled MOFs composite exhibited enhanced adsorption and photocatalysis performance, with nearly 100% removal of tetracycline achieved within 12 minutes of solar-light irradiation. The obtained rate constant was significantly higher than other materials, demonstrating the potential of Co-MIL-10 as an efficient catalyst for pollutant degradation.

Summary: Here, it is demonstrated that the addition of Lewis acid co-catalysts can greatly expand the range of alkenes that can participate in the photosensitized visible-light De Mayo reaction. Mechanistic studies indicate that the primary advantage of Lewis acid is not on substrate sensitization, but rather on bond-forming steps after energy transfer, illustrating the versatile effects Lewis acids can have on sensitized photoreactions.

Summary: Ag-TiO2-x nanocomposites were fabricated by Ag+ ion exchange, exhibiting strong visible-light absorption and hot electron generation. The introduction of Ag nanoparticles led to the formation of anatase-rutile heterojunction and narrowed the bandgap, facilitating the photocatalytic reduction of Cr (VI) under visible light. The synergistic effect of Ti3+ defect energy level, anatase-rutile heterojunction, and SPR effect of Ag nanoparticles was proposed as the photocatalytic reduction mechanism.

Summary: The study investigates the photocatalytic performance of Au/TiO2 and TiO2-HNO3 for water splitting and the degradation of methylene blue (MB). The results show that 1% Au/TiO2-HNO3 exhibits good photocatalytic activity with high hydrogen evolution rate and MB degradation efficiency under visible light irradiation. The TiO2-HNO3 homojunction structure enhances charge transfer and decreases the electron-hole recombination, while the strong metal-support interaction and localized surface plasmon resonance (LSPR) of Au species contribute to the superior performance of Au/TiO2.(c) 2022 Hydrogen Energy Publications LLC.

Summary: Perovskite solar cells (PSCs) have attracted much attention in the field of science and technology due to their impressive power conversion efficiency (PCE). However, little research has been conducted on the preparation processes and micro-mechanisms of large-area PSCs. Current achievements in high efficiency and stability of large-area PSCs have been summarized, but further research is needed for the commercialization of PSCs in the future.
