Summary: This study investigates the use of transition metal-doped zinc oxide/reduced graphene oxide (ZnO/rGO) nanostructures for photocatalytic applications. A cost-effective electrospinning-assisted hydrothermal method is proposed to synthesize these nanostructures. The results show that the doping of transition metals and the presence of rGO improve the photocatalytic activity of ZnO, by enhancing the separation of photogenerated electron-hole pairs and inhibiting their recombination. Despite challenges in controlling the doping process, transition metal-doped ZnO/rGO nanostructures show promise for efficient and sustainable photocatalytic applications in the future.

Summary: This review updates the research in the field of enantioselective domino reactions promoted by chiral catalysts derived from first row metals, such as zinc, iron, copper, scandium, nickel, cobalt, titanium, chromium and magnesium, since the beginning of 2019. It illustrates the impressive range of novel highly enantioselective domino reactions that can be achieved with a diversity of these catalysts, providing a one-pot access to very complex and functionalized chiral molecules from simple starting materials.

Summary: Rechargeable zinc-air batteries are considered a promising technology for energy conversion and storage, offering a cost-effective alternative to lithium-ion batteries. However, their practical application is hindered by slow reaction kinetics. Recent research has focused on using first-row transition metals as efficient and durable bifunctional electrocatalysts for the oxygen reduction and evolution reactions in zinc-air batteries. This review provides a comprehensive summary of the mechanisms, performance, and preparation strategies of these electrocatalysts in alkaline media and discusses future research trends.

Summary: A series of hierarchically sponge-like Sn4+-doped ZnO materials were successfully fabricated using biomass template-assisted hydrothermal and calcination strategies without the need for alkali precipitants. The photocatalytic degradation efficiency of these materials was found to be higher than that of pure ZnO, with the optimal catalyst being Sn4+/ZnO-600.

Summary: The contamination of water resources is a major environmental concern, especially the presence of hazardous pollutants such as phenol. Therefore, developing cost-effective techniques to remove phenol from water is crucial. This study investigated the use of silver-doped zinc oxide nanorods (Ag-ZnO NRs) for the degradation of phenol under sunlight. The synthesized Ag-ZnO NRs exhibited two distinct structures, hexagonal and cubic, and their optical properties showed significant improvement due to silver doping. The 0.5% Ag-doped ZnO NRs showed the highest photocatalytic activity, achieving a degradation rate of 98.5% for phenol removal under solar light irradiation after 5 hours.

Summary: Copper-doped zinc sulfide (ZnS:Cu) is a versatile phosphor material that exhibits down-conversion luminescence in various regions of the electromagnetic spectrum. Colloidal nanocrystals (NCs) of ZnS:Cu are of particular interest for quantum information science due to their precise control over size, composition, and surface chemistry. The researchers propose a method for synthesizing ZnS:Cu NCs that primarily emit red light, and they explore the thermodynamic stability and electronic structure of the CuZn-VS complex. The understanding of the emission dynamics and controlled synthesis of CuZn-VS in ZnS NCs will contribute to the development of quantum point defects in this material.

Summary: The interaction between graphene oxide (GO) and methylene blue (MB) cationic dye in an aqueous solution was investigated using FTIR and XRD. The results indicate that pi-pi and electrostatic interactions are the main types of interactions between MB and GO surface. The functional groups and point of zero charge (PZC) of GO were determined by acid-base titration. Additionally, the maximum adsorption capacity of GO increases with higher pH.
