Abstract Bifunctional electrocatalysts with high efficiency, stability, and distinguished performance have attracted more attention in the field of overall water splitting, while composition structure design are very essential for superb low price. In this work, heterostructure Mn‐Co‐Fe‐P nanoarrays is situ grown on nickel foam (NF) by simple hydrothermal method phosphating method. The resultant catalyst has favorable electrocatalytic oxygen evolution reaction (OER) overpotential at 10 (100) mA cm −2 192 (279) mV Tafel slope 43.75 dec −1 , hydrogen (HER) 98 (152) 40.68 full voltage 1.66 V 100 when applied to splitting. 3D provides active sites, growth improves stability conductivity catalyst. This binder‐free electrocatalyst excellent catalytic a promising bifunctional candidate

Developing high-performance materials for energy storage and water splitting remains a significant challenge in research. Metal selenides, such as CdSe, exhibit excellent electrical conductivity electrochemical activity, but they tend to form aggregates. Two-dimensional (2D) Ti3C2Tx MXene has good stability is limited by its low capacitance electrocatalytic performance. To address these issues, CdSe@Ti3C2Tx composites were synthesized two-step large-scale hydrothermal method, where CdSe nanoparticles uniformly grown on nanosheets. The significantly enhance the specific capacity, ion mobility, cycling stability, catalysis activity due synergistic effect between nanoparticles. In three-electrode system, achieve of 1847 F g-1 at 0.125 mA cm-2 retain 89.2% their after 10 000 cycles, demonstrating superior properties compared those CdSe- or Ti3C2Tx-based electrodes. asymmetric supercapacitor (ASC) with positive electrode activated carbon (AC) negative 219.1 g-1, capacity retention 88.1% 5000 an density 45.8 W kg-1. This research also analyzes reasons performance enhancement from perspective states theory. Furthermore, composite shows catalytic potential splitting, overpotentials 201 mV hydrogen evolution reaction (HER) 276 oxygen (OER). These results suggest that 2D MXene-based promising candidate splitting.

Abstract Metal‐organic frameworks (MOFs) and their derivatives have shown broad application prospects in fields such as water electrolysis, electrochemical energy storage, sensing due to high specific surface area, tunable structures, abundant active sites. This article provides a comprehensive overview of our research group′s recent advancements developing MOF‐based electrocatalysts for Oxygen Evolution Reaction (OER) Urea Oxidation (UOR) at anodes, well Hydrogen (HER) cathodes during electrolysis. Furthermore, we integrated these catalysts into practical applications, including metal‐air batteries, lithium‐sulfur non‐enzymatic glucose sensors. To further demonstrate the innovative contributions work, systematically compare it with advanced work by other groups. Based on findings performance benchmarking analyses, identify critical challenges that must be addressed advance MOFs‐based toward next‐generation conversion sensing.
