Summary: In this study, a series of novel B-site substituted KCuTa3-xNbxO9 solid solution photocatalysts were synthesized via a simple solid-state reaction method. By increasing the content of Nb, a red-shifted optical absorption edge, decreased bandgap, and positive shift of the conduction band bottom were observed, leading to enhanced separation efficiency of photoinduced charge carriers and increased hydrogen evolution activity. Among the photocatalysts, KCuTa0.75Nb2.25O9 exhibited the highest hydrogen evolution rate, approximately 7-fold higher than that of pure KCuTa3O9 under visible light irradiation.

Summary: Among various advanced oxidation processes, photocatalysis has gained attention in wastewater treatment due to its low cost, high efficiency, and eco-friendliness. Bismuth oxyhalides, with their unique layered structure, have been widely used as efficient photocatalysts for degrading organic pollutants in water. However, the large bandgap and high recombination rate of BiOCl and BiOBr limit their practical application. This study successfully prepared solid solutions of BiOCl1-xBrx using a solid-state reaction, and their photocatalytic performance was significantly improved compared to the individual components. The optimal composition of x=0.5 showed high degradation efficiencies for rhodamine B and tetracycline under LED irradiation.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
