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.

Keys to Unravel the Stability/Durability Issues of Platinum-Group-Metal Catalysts toward Oxygen Evolution Reaction for Acidic Water Splitting

ACS Central Science, Journal Year: 2024, Volume and Issue: 10(11), P. 2006 - 2015

Published: Nov. 13, 2024

Proton exchange membrane (PEM) water electrolyzers stand as one of the foremost promising avenues for acidic splitting and green hydrogen production, yet this electrolyzer encounters significant challenges. The primary culprit lies in not only requirements substantial platinum-group-metal (PGM)-based electrocatalysts (e.g., IrOx) at anode where sluggish oxygen evolution reaction (OER) takes place, but also harsh high overpotential environments leading to severe performance degradation. key points obtaining accurate stability/durability information on OER catalysts have been well agreed upon, contrast reduction fields. In regard, we herein reviewed discussed pivotal experimental variables involved testing (including limited electrolyte, impurity, catalyst loading, two/three-electrode vs membrane-electrode-assembly), while test protocols are revisited summarized. This outlook is aimed highlighting reasonable effective accelerated degradation procedures unravel instability issues promote research development a PEM electrolyzer.

Solid-State-Electrolyte Reactor: New Opportunity for Electrifying Manufacture

JACS Au, Journal Year: 2025, Volume and Issue: 5(2), P. 521 - 535

Published: Feb. 6, 2025

Electrocatalysis, which leverages renewable electricity, has emerged as a cornerstone technology in the transition toward sustainable energy and chemical production. However, traditional electrocatalytic systems often produce mixed, impure products, necessitating costly purification. Solid-state electrolyte (SSE) reactors represent transformative advancement by enabling direct production of high-purity chemicals, significantly reducing purification costs consumption. The versatility SSE extends to applications such CO2 capture tandem reactions, aligning with green decentralized paradigm. This Perspective provides comprehensive overview reactors, discussing their principles, design innovations, producing pure chemicals─such liquid carbon fuels, hydrogen peroxide, ammonia─directly from other sources. We further explore potential highlighting compatibility versatile systems. Finally, we outline future research directions for underscoring role advancing manufacturing.
