Electrochemical water splitting represents one of the most promising technologies to produce green hydrogen, which can help realize goal achieving carbon neutrality. While substantial efforts on a laboratory scale have been made for understanding fundamental catalysis and developing high‐performance electrocatalysts two half‐reactions involved in electrocatalysis, much less attention has paid doing relevant research larger scale. For example, few such researches done an industrial Herein, we review very recent endeavors bridge gaps between applications electrolysis. We begin by introducing fundamentals electrochemical then present comparisons testing protocol, figure merit, catalyst interest, manufacturing cost industry‐based water‐electrolysis research. Special is tracking surface reconstruction process identifying real catalytic species under different conditions, highlight significant distinctions corresponding mechanisms. Advances designs industry‐relevant electrolysis are also summarized, reveal progress moving practical forward accelerating synergies material science engineering. Perspectives challenges electrocatalyst design strategies proposed finally further lab‐scale large‐scale electrocatalysis applications.

Activating Amorphous Ru Metallenes Through Co Integration for Enhanced Water Electrolysis

Advanced Energy Materials, Journal Year: 2023, Volume and Issue: 13(28)

Published: June 11, 2023

Abstract Designing efficient bifunctional electrocatalysts with excellent activity and robust stability presents a central challenge for the large‐scale commercialization of water electrolysis. Herein, facile approach is reported construct atomically thin amorphous RuM (MCo, Fe, or Ni) bimetallenes as high‐performance toward both electrochemical hydrogen evolution reaction (HER) oxygen (OER). The RuCo bimetallene manifests characterized by low required overpotentials, superior price activity, durability well cell potential splitting performance, outperforming Pt/C RuO 2 benchmark catalysts. Combined operando X‐ray absorption spectroscopy investigation theoretical simulations reveal synergism taking place between binary constituents, in which Co serves promotive role along HER/OER pathway, contributing via optimal binding to *OH dissociation modulating Ru electronic structure favorably, hence rendering high catalytic centers alkaline HER OER.

NiFe layered double hydroxide nanosheet array for high-efficiency electrocatalytic reduction of nitric oxide to ammonia

Chemical Communications, Journal Year: 2022, Volume and Issue: 58(58), P. 8097 - 8100

Published: Jan. 1, 2022

Here, we demonstrate that under ambient conditions, a nickel-iron layered double hydroxide nanosheet array can exhibit promising NORR performance, delivering maximal faradaic efficiency of 82% and corresponding yield rate 112 μmol h-1 cm-2, along with high stability for over 30 h. This superior performance is further confirmed as proof-of-concept Zn-NO battery, in which peak power density 1.8 mW cm-2 large NH3 32 are observed. Theoretical analyses indicate NiFe-LDH exhibits effective NO activation capacity slow hydrogen evolution kinetics.
