Summary: Coupling a semiconductor with exposed high-activity crystal facets and a suitable co-catalyst to form a heterojunction is an effective way to enhance photocatalytic activity. The novel BiOBr/(001)-TiO2/Ti3C2Tx (BTT-y) shows remarkable Rhodamine B (RhB) degradation performance due to better synergy among the three substances. The improvement of RhB degradation performance is mainly attributed to the perfect matching of BiOBr and (001)-TiO2 band structure positions, which promotes the formation of heterojunction, extends visible-light absorption range, and inhibits carrier recombination.

Summary: Metal phthalocyanines molecular catalysts demonstrate unique ability in CO2 electrochemical reduction reaction (CO2ERR) due to their well-defined macrocycle structure. By introducing different substituent functional groups on the phthalocyanine ring of cobalt phthalocyanine, the relationship between molecular structure optimization and CO2ERR activity was studied. An optimal nitro-substituted cobalt phthalocyanine catalyst can achieve high selectivity of 94% in converting CO2 to CO, with a current density of 12.6 mA cm(-2) at -0.877 V vs. RHE. Insights gained from this study on designing and optimizing molecular catalysts contribute to lower energy and cost-effective CO2ERR.

Summary: This study demonstrates the double-edged sword effects of the methylammonium chloride (MACl) additive on the properties of methylammonium lead mixed-halide perovskite (MAPbI(3-x)Cl(x)) films and perovskite solar cells (PSCs). Undesirable morphology transition occurs in MAPbI(3-x)Cl(x) films during annealing, affecting the film quality, optical properties, structure, defect evolution, and power conversion efficiency (PCE) of related PSCs. A post-treatment strategy called FAX (FA = formamidinium, X = I, Br, and Ac) is developed to inhibit morphology transition and suppress defects, resulting in a champion PCE of 21.49% and impressive stability.

Summary: The abuse of tetracycline and other drugs leads to the accumulation of antibiotics and their metabolites in the water system, posing a threat to human life. This study developed a novel Z-scheme heterojunction for efficient photocatalytic degradation of tetracycline using a Bi12O17Br2/(001)-TiO2 catalyst. Unlike traditional Z-scheme heterojunctions, (001)-TiO2 acts as an electron syringe, promoting special charge transfer and enhancing the efficiency of electron hole pair separation and transfer. The stacked layered structure of the catalyst also increases the specific surface area, allowing for better pollutant adsorption and increased reactive active site. The degradation efficiency of the BT5 catalyst for tetracycline solution reached 99.76% in 50 min, and it maintained a high degradation rate of 93.50% after four cycles. This study provides new design ideas for the removal of antibiotic pollutants using novel Z-scheme structures.

Summary: The 20NaF-60P2O5-20Na2O fluorophosphate glass systems doped with 3 wt% of CoO and NiO were investigated for their optical parameters before and after gamma irradiation. The presence of defects within the glass network and the addition of transition metals were found to affect the properties of the composites. After irradiation, a red shift was observed in the dissipation factor spectrum. The energy lost at the surface of the composites was larger than the energy lost within the constituent materials. All investigated composites showed insulating behavior and exhibited increased nonlinear optical parameters after irradiation, with the CoO-doped composite showing the highest values.
