Summary: This study focused on the improved visible light photocatalytic activity of Bi2S3-TiO2 nanocomposite for phenol degradation, which was synthesized by solvothermal method. FE-SEM, XRD, and TEM analyses confirmed the successful synthesis of Bi2S3-TiO2 nanocomposite. Electrochemical experiments showed low recombination rate and faster interfacial charge transfer in Bi2S3-TiO2 nanocomposite. Optical analyses indicated bandgap energies of 3.15 eV, 1.32 eV, and 2.55 eV for TiO2 nanorods, Bi2S3 nanoparticles, and Bi2S3-TiO2 nanocomposite, respectively. Photocatalytic degradation analyses demonstrated successful treatment of phenol solution by TiO2 nanorods, Bi2S3 nanoparticles, and Bi2S3-TiO2 nanocomposite, with different exposure times. Application of Bi2S3-TiO2 nanocomposite for phenol degradation in real-world samples showed effective treatment of phenol in industrial wastewater through photocatalytic degradation.

Summary: Photocatalysis is an effective method for degrading organic pollutants using sunlight. This study developed a composite photocatalyst consisting of CuWO4 and graphene quantum dots (GQDs) to achieve better visible light activity. Different amounts of CuWO4 were used to prepare a series of photocatalysts, and their activity for phenol degradation was evaluated. The optimized sample, 0.5GCW, showed the highest efficiency of 53.41%, compared to the pure CuWO4 sample with 19.08% efficiency. Enhanced activity of CuWO4 is attributed to efficient electron transfer to GQDs. The results indicate that GQDs significantly contribute to the improvement of photocatalytic performance with CuWO4.

Summary: Photocatalytic active metal-organic frameworks (PA-MOFs) and MOFs-derived photocatalyst have been extensively used in various heterogeneous photocatalytic applications due to their high crystallinities, controllable dimensions, and tuneable textural properties. Recent modification approaches have been employed to improve their physicochemical properties and enhance their photocatalytic performance for sustainable solar-driven environment and renewable energy applications. However, a deep understanding of the correlation between the physicochemical properties and photocatalytic performance of PA-MOFs and MOFs-derived photocatalyst remains to be explored.

Summary: A novel Z-scheme CdS/CeO2/g-C3N4 nanocomposite was synthesized by a solvothermal method and its photocatalytic activity for the degradation of phenol was evaluated. The nanocomposite exhibited remarkable photocatalytic activity with a degradation rate of 95 % in 180 min, surpassing that of pure CeO2 and CdS/CeO2. The enhanced photocatalytic ability is mainly attributed to the higher adsorption capacity of three-dimensional porous g-C3N4 and the three-dimensional space electric field formed by its complex with CdS and CeO2.

Summary: The combination of covalent organic frameworks (COFs) and ideal semiconductors can greatly enhance the photocatalytic performance for pollutant degradation. In this study, a core-shell-structured nanocomposite composed of Fe3O4 magnetic particles encased in a covalent triazine framework (CTF) shell was synthesized and characterized as a heterojunction photocatalyst for phenol degradation using peroxymonosulfate (PMS). The internal structure of the Fe3O4@TpMa system facilitated charge transfer and accelerated charge separation, while PMS served as an electron acceptor to enhance charge separation and generate reactive oxygen species. The Fe3O4@TpMa/PMS system exhibited outstanding photocatalytic performance and stability, achieving complete phenol degradation in 40 minutes.

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.
