Defect engineering is an effective way to modulate the electric states and provide active sites for electrocatalytic reactions. However, most studied oxygen vacancies are unstable susceptible under circumstance. Here, we fabricated cobalt-defected Co3–xO4 in situ efficient evolution reaction (OER). XAFS PALS characterizations show that crystals have abundant Co a distorted structure. DFT calculations indicate metal defects lead obvious electronic delocalization, which enhances carrier...
The design of efficient catalysts that synergistically promote *H2O decomposition, H2 formation, and desorption is critical to accelerate hydrogen evolution reaction (HER) kinetics but remains a significant challenge.

Abstract Hydrogen peroxide (H 2 O ) is a highly value‐added and environmental‐friendly chemical with various applications. The production of H by electrocatalytic 2e − oxygen reduction reaction (ORR) has emerged as promising alternative to the energy‐intensive anthraquinone process. High selectivity Catalysts combining superior activity are critical for efficient electrosynthesis . Earth‐abundant transition metal selenides (TMSs) being discovered classic stable, low‐cost, active selective...
The electrochemical N2 reduction reaction (NRR) is a green and energy-saving sustainable technology for NH3 production. However, high activity selectivity can hardly be achieved in the same catalyst, which severely restricts development of NRR. In2Se3 with partially occupied p-orbitals suppress H2 evolution (HER), shows excellent presence VIn simultaneously provide active sites confine Re clusters through strong charge transfer. Additionally, well-isolated stabilized on by confinement effect...
Abstract Electrocatalytic nitrogen reduction reaction (NRR) is a potential strategy for green synthesis of ammonia.

The rich interface low‐coordination helps provide more active sites At same time, nucleus gives electrons shell, jointly promotes...
Electrocatalytic reduction of NO3‐ is a green and sustainable method that not only helps to treat industrial pollutants in wastewater, but also produces valuable chemicals. However, the slow dynamics proton‐coupled electron transfer process results high barrier low conversion efficiency.

Abstract Three‐dimensional asymmetric supercapacitors (3D ASC) have garnered significant attention due to their high operating window, theoretical energy density, and circularity. However, the practical application of 3D electrode materials is limited by brittleness excessive dead volume. Therefore, we propose a controlled contraction strategy that regulates pore structure materials, eliminates volume in skeleton structure, enhances mechanical strength. In this study obtain reduced graphene...
