Summary: The study presents a facile one-step redox reaction to fabricate Bi2O2CO3/Bi2O3/Bi ternary composite, with ethylene glycol used as both the solvent and reductant. Through the optimization of component proportions, the ternary composites demonstrate enhanced photocatalytic efficiencies under simulated solar light, attributed to the accelerated migration rate of charge carriers resulting from the construction of heterojunction and decoration of cocatalyst.

Summary: In this study, the Bi2O2CO3/Bi2S3 heterojunction was prepared using a one-step hydrothermal method, with Bi(NO3)3 as the Bi source, Na2S as the sulfur source, and CO(NH2)2 as the C source. The loading of Bi2S3 was adjusted by varying the content of Na2S. The prepared Bi2O2CO3/Bi2S3 exhibited strong photocatalytic activity towards dibutyl phthalate (DBP) degradation, with a degradation rate of 73.6% under visible light irradiation for 3 hours, which was 3.5 and 1.87 times higher than that of Bi2O2CO3 and Bi2S3, respectively. Furthermore, the mechanism behind the enhanced photoactivity was investigated, and it was found that the formation of the heterojunction structure inhibited the recombination of photogenerated electron-hole pairs, improved visible light absorption, and accelerated the migration rate of photogenerated electrons. The S-scheme heterojunction model was consistent with the analysis of radical formation and energy band structure, and this heterojunction allowed for high photocatalytic activity of Bi2O2CO3/Bi2S3. The prepared photocatalyst also exhibited acceptable cycle application stability, providing a facile synthesis technique and a promising platform for DBP degradation.

Summary: This article summarizes the application of metal-free graphitic carbon nitride (g-C3N4) based direct and indirect Z-scheme photocatalysts in solar-driven advanced oxidation processes (AOPs) for the removal of organic pollutants from water. The classification of AOPs, definition and validation of Z-schemes are discussed, followed by an examination of the engineering strategies for CN-based direct Z-scheme structure and the design of indirect CN-based Z-scheme systems using different charge mediators. The relationship between Z-scheme structure and activity is studied to gain insights into improving the catalytic performance of CN-based Z-schemes in AOPs.

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.
