Summary: MXenes-based nanomaterials show great potential as efficient and low-cost electrocatalysts for oxygen reduction reaction. Their synthesis strategies, electronic and structural properties, and ORR performance are of significant importance. However, there are still challenges and potential aspects that need further research.

Summary: In this study, the Fermi-level (E-F) shift of the UV-illuminated Ag/TiO2 system under gaseous conditions was evaluated using in situ photoconductance and theoretical analysis. The role of Ag nanoparticles in storing and separating electrons was discussed, and it was found that the E-F of Ag/TiO2 is located deeper in the gap and is less affected by temperature compared to undecorated TiO2. The analysis showed that approximately 46 electrons can be stored in 10 nm Ag nanoparticles under the experimental conditions, and the blue-shift of localized surface plasmon resonance (LSPR) in Ag nanoparticles is not related to electron storage.

Summary: In this study, a facile top-down approach was developed to directly grow Co3O4 hierarchical nanoflowers from a bulk Co surface via chemical etching and thermal annealing. The annealing temperature was found to have a significant effect on the formation of Co3O4, with amorphous Co3O4 formed at 250 degrees C and crystalline Co3O4 with notable oxygen vacancies created at 550 degrees C. The resulting 3D nanostructures exhibited excellent oxygen evolution reaction (OER) activities and durability.

Summary: Recently, silsesquioxanes (SSQ) and polyhedral oligomeric silsesquioxanes (POSS) have attracted attention in biomaterials due to their unique properties. Their potential applications in dentistry are still in the early stage, but have great potential for future development. By incorporating POSS into dental materials, various issues like polymerization shrinkage, water absorption, and corrosion resistance can be addressed. The presence of silsesquioxanes allows for the development of smart materials with phosphates deposition stimulation and self-repairing ability. Additionally, POSS-containing composites can be used for bone reconstruction and wound healing.

Summary: This paper reports on the excellent oxygen reduction activity and durability of a composite structure consisting of highly active V2O5-WO3 electrocatalyst under alkaline conditions. The 25 wt.% V2O5 with 75 wt.% WO3 catalyst exhibited outstanding catalytic performance, attributed to the optimum concentration of V2O5, high surface area, conductivity, and mesoporous nature.

Summary: This study demonstrates the visible light-driven production of H2O2 by modulating the size of Au nanoparticles. It is found that medium-sized Au particles exhibit the highest catalytic activity. The relationship between particle size and catalytic performance is supported by experimental and theoretical methods, showing that medium-sized Au particles promote photon absorption, enhance O-2 adsorption, and inhibit H2O2 decomposition.

Summary: This study investigates the catalytic potential of two-dimensional Nb2O5 for alkali metal-oxygen batteries and analyzes the impact of oxygen defects on its catalytic performance mechanism. The exploration uncovers how oxygen deficiency affects the reaction and provides a theoretical basis for quantitatively altering the performance of the catalyst by changing the d-band center through oxygen deficiency.

Summary: Fe-Co bimetallic electrocatalysts with size-modulated FeCo binary alloys exhibit superior electrocatalytic activity and stability in the alkaline medium, showing great potential to replace precious metal catalysts for ORR and OER. The optimized template with abundant carbon nanotubes and uniform distribution of FeCo alloy nanoparticles achieved a high-performance half-wave potential of 0.88 V toward ORR and a comparable open-circuit potential to Pt/C+IrO2 in the liquid Zn-air battery. Our findings provide new prospects for understanding metal particle sizes and electrocatalytic performance of pyrolyzed transition metal-carbon materials.

Summary: Oxygen reduction reaction (ORR) is a key step in fuel cells. Finding efficient electrocatalysts is important for commercialization. Platinum and its alloys are the main active materials used, but their high cost and susceptibility to time-dependent drift limit their applicability. Nanostructured transition metal phthalocyanine complexes (MPc) show satisfactory catalytic activity in ORR, indicating their potential as a replacement for precious-metal catalysts. This review analyzes the problems of MPc based on its chemical structure and microstructure characteristics, and proposes a strategy to control the structure of MPc to improve the catalytic performance of ORR.

Summary: In this study, hybrid nanocomposites were successfully synthesized by photo-crosslinking, resulting in the in situ formation of silver nanoparticles in the hybrid network. The addition of a small amount of POSS-(PEG(2000))(8) significantly enhanced the thermal stability, and films containing only POSS-(PEG(2000))(8) exhibited the highest swelling ratio in a short amount of time.
