Abstract Metal selenides with excellent electronic conductivity and high theoretical capacity present great superiority as alternative anodes in sodium ion batteries (SIBs). However, they face huge challenges such severe polyselenides shuttling slow diffusion kinetics. To address these issues, entropy regulation strategy is employed to optimize the presence of Se vacancies successfully prepared NiCoFeMnCr/CNTs (HE‐MSe/CNTs) rich vacancies. This material enhances adsorption energy for shuttle compounds like Na 2 4 , effectively limiting dissolution improving kinetics ions well structural thermodynamics x HE‐MSe/CNTs phase. Experimental results indicate that achieve a highly reversible storage process involving intercalation conversion reaction mechanisms. enables superior rate capability 400.4 mAh g −1 at current density 5 A long‐term durability 90% retention after 1000 cycles 1 . Therefore, utilizing customize vacancy formation provides new insights methods enhancing performance SIB anodes.

Abstract Oxygen evolution reaction (OER) is a cornerstone of various electrochemical energy conversion and storage systems, including water splitting, CO 2 /N reduction, reversible fuel cells, rechargeable metal‐air batteries. OER typically proceeds through three primary mechanisms: adsorbate mechanism (AEM), lattice oxygen oxidation (LOM), oxide path (OPM). Unlike AEM LOM, the OPM via direct oxygen–oxygen radical coupling that can bypass linear scaling relationships intermediates in avoid catalyst structural collapse thereby enabling enhanced catalytic activity stability. Despite its unique advantage, electrocatalysts drive remain nascent are increasingly recognized as critical. This review discusses recent advances OPM‐based electrocatalysts. It starts by analyzing mechanisms guide design Then, several types novel materials, atomic ensembles, metal oxides, perovskite molecular complexes, highlighted. Afterward, operando characterization techniques used to monitor dynamic active sites examined. The concludes discussing research directions advance toward practical applications.

Interface design plays a pivotal role in developing high-performance photocatalysts for NO oxidation. In this work, hierarchical rGO-integrated NH2-MIL125(Ti)/TiO2 photocatalyst was constructed using combined liquid-phase and solid-phase microwave synthesis approach. The process enabled the precise deposition of NH2-MIL125(Ti) on graphene oxide (GO), forming strong interfacial bonds, while thermal shock (SMTS) transformed GO into rGO induced formation TiO2 nanoparticles. This structure established an efficient electron transport pathway, promoting charge separation directional transfer to activate O2 generate superoxide radicals (•O2–) as primary reactive species. resulting achieved remarkable oxidation performance, with 81.2% removal efficiency NO3– selectivity 98.5% under simulated sunlight. study highlights potential microwave–driven interface engineering innovative environmentally sustainable applications.

Abstract Acidic overall water‐splitting driven by consistent electricity is an efficient and economical method for producing green hydrogen. However, developing highly active durable bifunctional electrocatalysts both hydrogen oxygen evolution reactions (HER OER) in acidic conditions remains a challenge. Here, single‐atom Mn sites are introduced into Ru/RuO₂ heterostructures (Mn(SAs)‐Ru/RuO 2 ) as electrocatalysts, achieving low overpotentials of 39 158 mV at 10 mA cm −2 HER OER, respectively, while maintaining long‐term durability over 500 h 1.47 V 0.5 m H SO 4 . It outperforms most previously reported electrocatalysts. Theoretical calculations show that the charge redistribution caused single‐site dopants optimizes adsorption OOH * Ru sites, significantly boosting electrochemical kinetics OER HER. This work presents effective metal doping strategy to optimize distribution water‐splitting.
