Abstract In‐depth comprehension and improvement of the sluggish hydrogen evolution kinetics in alkaline media is highly important to enhance activity durability anion exchange membrane water electrolysis (AEMWE) for green production. Herein, a atom‐terminated core–shell PdH@Ru nanobamboos (NBs) developed by synergetic strategy epitaxial growth situ DMF hydrogenation. The synthesized NBs demonstrate exceptional reaction (HER) media, requiring only 14 mV overpotential at 10 mA cm −2 , surpassing those commercial Pt/C (35 mV) H‐free Pd@Ru (37 mV). Furthermore, an AEMWE device using as cathode also achieves current density 1000 − 2 ≈1.80 V 1.0 m KOH 60 °C, with continuous operation 50 h. operando spectroscopic analysis functional theory calculations suggest that insertion into induces tensile strain on Ru surface layer, altering Pd/Ru electronic structure weakening H adsorption, thereby enhancing HER efficiency. bamboo‐like hollow features numerous active sites, which contribute optimization electron/mass diffusion electrolyte. This work provides potential high‐efficiency cathodic electrocatalyst industrial

Abstract Hydrogen, a sustainable alternative to fossil fuels, can be efficiently produced by electrochemical water splitting, which involves hydrogen evolution reaction (HER) at the cathode and oxygen (OER) anode. Both HER OER require electrocatalysts. The large scale implementation of this technology depends heavily on development highly active, stable, cost‐effective In view this, several electrocatalysts have been explored. Herein, electrocatalytic performance MnCO 3 synthesized hydrothermal method is reported. While chosen as electrocatalyst owing cost‐effect abundant precursors, environmental friendliness, good activity, for its simplicity, efficiency, scalability. micron size hydrothermally exhibits η 10 143 mV, Tafel slope 72 mV dec −1 retains over 3000 cycles 14 h continuous operation in 0.5 M H 2 SO 4 , demonstrating utility production.

Abstract The design of efficient alkaline hydrogen evolution reaction (HER) electrocatalysts is crucial for the development green production. In this work, we report modulation HER activity Ru nanoparticles by functionalization using para‐substituted phenylacetylenes (R = Cl, H, C 2 H 5 , and OCH 3 ), which have different electron donating/withdrawing capabilities. A close correlation between Hammett substituent constant functionalized revealed, underlying mechanism investigated. Guided such correlation, 4‐ethylphenylacetylene‐modified (Ru─EPA) with a low overpotential 17.7 mV at current density 10 mA cm −2 in solution developed. mechanistic understanding gained work will provide important guidelines future high‐performance nanostructured electrocatalyst.
