Summary: A heterostructure material g-C3N4/SrZrO3 was prepared by grinding and heating a mixture of SrZrO3 and g-C3N4. The synthesized photocatalysts were characterized by various techniques, including SEM, XRD, XPS, EDS, HRTEM, and infrared spectra. The g-C3N4/SrZrO3 material exhibited visible light absorption ability and significantly higher photocatalytic activity than pristine g-C3N4 or SrZrO3. The enhanced photocatalytic performance was attributed to the efficient separation of photogenerated electrons and holes facilitated by the cooperation of g-C3N4 and SrZrO3, as demonstrated by photocurrent measurements.

Summary: Antibiotic contamination is a growing concern, leading to increased scrutiny on solutions like the AgAgCl/WO3/g-C3N4 (AWC) nanocomposites for trimethoprim degradation. Experimental results showed high efficiency with 99.9% of TMP degraded within 60 min using AWC at 0.5 g/L concentration. The proposed double photoelectron-transfer mechanism and identification of degradation pathways through theoretical calculations and experiments further support AWC as a promising photocatalyst for removing TMP from aquatic environments.

Summary: In this study, a series of graphitic carbon nitride/ZnTi-mixed metal oxide (CN/ ZnTi-MMO) composites were prepared for the photocatalytic degradation of ciprofloxacin (CIP). The optimized CN/ZnTi-MMO composite showed a complete degradation of CIP within 20 minutes, with a degradation rate approximately 6 times that of pristine CN and 7 times that of ZnTiMMO. The improved degradation rate was attributed to the effective separation and transportation of photogenerated electron-hole pairs, as well as the formation of interfacial electron trap states in the composite. The degraded solution exhibited lower bio-toxicity compared to the original CIP solution.

Summary: This study investigated the photocatalytic degradation performance of different compositions of zinc oxide anchored on graphitic carbon nitride on antibiotics. The results showed that 15% ZnO composition exhibited superior properties. High-resolution transmission electron microscopy revealed the intercalation of nanoparticles between the sheets, greatly enhancing the photocatalytic and electrochemical properties. The optimal conditions for the photocatalytic degradation of tetracycline were determined to be 15 mg of the superior material, 50 mL of the 10-ppm concentration, and 120 min of irradiation, which removed over 95% of the antibiotic.

Summary: Dye effluent poses a serious threat to water ecosystem and human health, necessitating the development of efficient semiconductor photocatalysts to tackle water pollution. In this study, a novel 0D/2D hierarchical heterostructure AgI/CAU-17 composite was fabricated, exhibiting significantly enhanced photocatalytic performance for RhB, TC, and MO degradation compared to CAU-17 and AgI alone. The improved performance can be attributed to the tight interfacial contact, type II charge migration pathway, and increased light absorption capacity and specific surface area provided by the AgI/CAU-17 heterostructures. This research demonstrates the great potential of AgI/CAU-17 heterojunctions in water purification and provides a simple and reliable approach for the preparation of Bi-MOFs composite photocatalysts.

Summary: A novel type II BiOCl/CAU-17 2D/2D heterostructure photocatalyst was synthesized via in situ growth of ultrathin BiOCl on the surface of CAU-17 nanorods through a solvothermal process. The 2D/2D heterostructures provide a large specific surface area and tight interfacial contact, which facilitate carrier migration. The introduction of CAU-17 enhances the light absorption ability of BiOCl/CAU-17 photocatalysts. The staggered type II heterostructure energy band alignment promotes the separation of photoexcited carriers.

Summary: Extensive research has revealed that oxygen evolution reaction (OER) in alkaline conditions involves dynamic surface restructuring. The development and design of sulfide/oxide pre-catalysts can reasonably adjust the composition and structure after surface reconstruction, which is crucial for OER. This study utilized a simple two-step hydrothermal method to achieve in situ S leaching and doping, inducing the composition change and structure reconstruction of CoFe oxides. The transformed FeOOH and CoOOH exhibited excellent OER activity and could be easily mass-produced using low-cost iron based materials and simple methods.

Summary: Zero-dimensional organic-inorganic metal halides (OMHs) are gaining attention in the fabrication of light-emitting diodes due to their broad emission band and high photoluminescence quantum yield. This work synthesized a zero-dimensional organic tetraphenylphosphonium bismuth chloride (TBC) that showed efficient blue light emission, with the emission mechanism attributed to the transition of Bi3+ ions. White light-emitting diodes (WLEDs) were fabricated using TBC, along with green-emitting and red-emitting single crystals, achieving single-component white emissions. These findings demonstrate the different emission mechanism of ns2 ions-based OMHs and highlight the potential of bismuth-based OMHs in WLEDs applications.

Summary: The revolutionary design concept of high-entropy alloys has brought new opportunities and challenges to the development of advanced metal materials. In this work, AlCrCuFe2NiTix high-entropy flux cored wires were prepared by combining the design idea of a high-entropy alloy with the characteristics of flux cored wire. AlCr-CuFe2NiTix high-entropy surfacing alloys were prepared using gas metal arc welding technology. The wear properties of the alloys were analyzed, and the phase composition, microstructure, strengthening mechanism, and wear mechanism were discussed. The results show that the alloys exhibit a dendritic microstructure with BCC/B2 + FCC phases. Increasing Ti content leads to the precipitation of Laves phase. The alloys show improved microhardness and wear resistance due to the precipitation of coherent B2 and Laves phases. However, excessive Ti addition results in the increase of Laves phase and reduced wear resistance of the alloys.

Summary: We conducted a study on the formation of ultra-fine Y-Ti-Ta-O nano-oxides in Ta+B micro-alloyed 13CrWTi-ODS alloys using electron microscopy and first-principles calculations. The Y-Ti-Ta-O nano-oxides were found to be mainly Y2(Ti,Ta)2O7, with an average size of 7 nm and a number density of 6.8 x 1023 m-3. Excess boron was found to enhance the adhesion of some low-sigma grain boundaries but weaken the Fe/Y2Ti2O7 interface, while excess tantalum enhanced the Fe/Y2Ti2O7 interface but caused serious degradation of grain boundaries.

Summary: The structure and magnetism of cobalt ferrites after Mn2+-Tb3+ co-doping were studied. Co-doped samples exhibited cubic spinel structure and spherical shape of ferrite nanoparticles. The redistribution of Co2+ and Fe3+ ions between octahedral and tetrahedral sites was observed due to Mn2+-Tb3+ co-doping. The coercivity and magnetization saturation of co-doped samples were significantly improved, leading to a maximum energy product that is 190% higher than that of the un-doped sample.

Summary: Recently, there has been an increasing interest in developing ultra-fine nanostructured electrodes with extensive reaction areas to enhance the performance and low-temperature operation of solid oxide fuel cells. The use of a refined approach involving co-sputtering metal alloys and oxide targets has demonstrated the feasibility of nano-columnar structures in perovskite-based electrodes, expanding the temperature range of thin film electrodes. This study systematically examines the effects of chamber pressure control in the co-sputtering process and identifies the intricate relationship between sputtering pressure and film structure. By fine-tuning the columnar growth in the electrode, significant improvements in performance and thermo-mechanical properties were achieved, resulting in high-performance all-sputtered solid oxide fuel cells.
