Development of efficient electrocatalysts for complete water splitting is crucial sustainable hydrogen production. Here, we report a highly active composite FeMn-layered double hydroxide (LDH) with molybdenum disulfide (MoS2) that exhibits significantly enhanced electrochemical water-splitting activity. The synergistic combination FeMn-LDH and MoS2 yields improved oxygen evolution reaction (OER) (HER) performances an overpotential 222 mV 120 at current density 10 mA/cm2, respectively. kinetics study FeMn-LDH/MoS2 was analyzed the help Tafel slopes 33.35 mV/dec OER process 112 HER process. electrocatalyst stable in both acidic basic media more than 24 h. overall electrocatalysis carried out using two-electrode systems (both electrodes as composites) having low voltage 1.64 V mA cm–2 density. activity attributed to increased surface area, charge transfer, modified electronic structure. This work demonstrates promising strategy designing sheds light on potential LDH/MoS2 composites energy applications.

Abstract Ruthenium (Ru)‐based hydrogen evolution reaction (HER) electrocatalysts are promising candidates for assembling high‐performance anion exchange membrane water electrolyzer (AEMWE) while their intrinsic activities restricted due to the strong Ru─H bond strength. Herein, we present synthesis and stabilization of electron‐deficient Ru nanoclusters on oxygen‐functionalized carbon nanotube (Ru/O‐CNT) via electronic metal‐support interaction (EMSI) toward highly efficient stable alkaline HER. A scalable high‐temperature shock method is used anchor O‐CNT, which suppresses aggregation clusters loss O during synthesis, thus strengthening EMSI between two components Ru–O–C link. The helps stabilize at state reductive potentials optimizes Consequently, Ru/O‐CNT delivers outstanding performances HER with a small overpotential 10 mV mA cm −2 , superior benchmark Pt/C most reported Ru‐based electrocatalysts. More impressively, an AEMWE assembled as cathode achieves high current densities 1 5 low cell voltages 1.68 2.09 V, respectively, mass loading only 20 µg .
