Summary: By coupling suitable cocatalysts, a dual-cocatalyst modified TiO2-based photocatalyst was constructed with a hollow spherical shell structure, which significantly improved the performance of photocatalytic hydrogen production. The incorporation of MoS2 and TiN enhanced the hydrogen evolution rate, attributed to more catalytically active sites, stronger light absorption, and better electron-hole separation effects. This work provides a strategy for the rational design of catalysts for further development in both mechanism understanding and practical application.

Summary: By constructing g-C3N4/MnFe2O4 heterojunction composites, the photocatalytic performance of g-C3N4 is successfully improved, achieving higher photocatalytic activity for CO2 reduction. The construction of g-C3N4 nanotubes increases its specific surface area and active sites for the reaction. The p-n heterojunction structure promotes electron-hole separation. The results show that under visible light irradiation, the CO yield of g-C3N4/MnFe2O4 composite can reach 1136.8 μmol h-1 g−1, which is 14 times higher than g-C3N4 nanotubes and 29 times higher than g-C3N4. This study provides guidance for the design of g-C3N4-based heterojunctions.

Summary: This study fabricated a ZnSe/Ag2Se/AgBr (ZAA) heterojunction by growing ZnSe on AgBr surface and in-situ generating Ag2Se between the two components. The results showed that ZAA exhibited excellent light response ability over the full wavelength range. XPS and ESR confirmed that the charge transfer of ZAA conformed to dual Z-scheme mechanism, with Ag2Se acting as an electron transfer bridge and electron reservoir to accelerate electron transfer and facilitate carriers' separation. The highest CO yield of 54.14 mu mol/g/h was obtained from the optimal ZAA-2, which was 11.76 and 10.44 times of pure ZnSe and Ag2Se, respectively. This work demonstrated the feasibility of a dual Z-scheme heterostructure with full spectrum response for providing stable electron-donating environment and improving electron transfer for enhanced photocatalytic activity.

The mSFO/P25 system showed photocatalytic reduction ability of CO2 to CO, which was confirmed by the use of labeled carbon dioxide. The surface photovoltage and electrochemical measurements supported the S-scheme mechanism.

Summary: A novel p-n heterojunction photocatalyst CsPbBr3/Co3O4 was fabricated by a facile microwave-assisted method, which simultaneously introduced oxygen vacancies and strengthened the interfacial interaction. The as-prepared catalyst displayed satisfactory photocatalytic CO2 reduction performance without photosensitizer and sacrificial agent. Experimental and computational results revealed that the oxygen vacancies and Cs-O bonds in this heterojunction led to the formation of strong built-in electric fields, accelerating charge separation and transfer.

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.
