Summary: The present work focuses on the hydrothermal synthesis of Bi2S3 and its doped materials for photocatalytic applications. The Ti-doped Bi2S3/1%NiO nanocomposite showed the highest photocatalytic efficiency among the synthesized samples, with an 80% elimination rate of methylene blue (MB) after 500 minutes of visible light illumination. The high photocatalytic activity can be attributed to the high BET surface area and p-n junction formed between Bi2S3 and NiO, as well as the increased band gap and improved transfer rate of photo-induced electrons due to Ti (IV) doping.

Summary: Photocatalysis has received significant attention in environmental remediation, with charge migration and solar light utilization being crucial for efficient performance. In this study, a ternary MoSe2/ZnO/p-BN (MZB) photocatalyst was successfully designed and synthesized. The optimal sample, with 30 wt% MZB, achieved a degradation rate of 99.2% for ofloxacin (OFL) under visible light irradiation, exhibiting catalytic reaction rates 5.33 times and 2.10 times higher than pure ZnO and ZnO/p-BN, respectively. The MoSe2/ZnO/p-BN system utilized p-BN to enrich pollutants and accelerate catalytic rates, while the hybridization of MoSe2 expanded the spectral response of the catalysts. The formation of stepped electron transport routes reduced the recombination rate of electron-hole pairs. Active species quenching experiments revealed that e(-), center dot O-2(-), h(+), and center dot OH played a major role in the removal of antibiotic contaminants. Analysis of OFL degradation intermediates provided insight into possible degradation pathways and proposed a reasonable photocatalyst mechanism. This work offers new ideas for the design of high-performance visible light responsive photocatalysts for pollution treatment.

Summary: This study investigates the photocatalytic activity of magnetic CoFe2O4/g-C3N4/ZnO (CF-gCN/ZnO) nanocomposite as a visible-light photocatalyst. The heterojunction CF-gCN/ZnO photocatalyst achieved a photodegradation efficiency of 89% for degradation of methylene blue (MB) after 100 min of irradiation. The formation of heterojunction structures at the interface of g-C3N4 and ZnO leads to improved photocatalytic activity due to the separation of the photo-generated electron-hole pairs.

Summary: In this study, a novel BiVO4/Bi25VO40 heterojunction was designed by the in situ conversion of pre-prepared BiVO4. The formation process and phase composition of the heterojunction were investigated, and it was found that the heterojunction formed through a dissolution-recrystallization process. By adjusting the alkali treatment conditions, the phase composition of the heterojunction can be precisely modulated, leading to enhanced photocatalytic performance in the probe reaction of tetracycline degradation. This study provides deeper insight into the rational design of highly efficient semiconductor photocatalysts.

Summary: NiCe/MnO2 nanosheets with oxygen vacancy (VO) and abundant active sites were prepared using a defect strategy, resulting in enhanced OER performance. The co-doping of Ce/Ni reduced particle size and increased surface area, promoting the exposure of more active sites. Heteroatom doping altered the crystalline surface species, stimulating the formation of VO and activating the catalyst simultaneously. This study presents a straightforward method for making non-precious metal electrocatalysts with high electrochemical hydrolysis performance.

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.
