The hydrazine oxidation reaction (HzOR) is considered as a promising alternative process of the oxygen evolution (OER) to realize more energy-efficient hydrogen generation. However, lack highly active bifunctional catalysts poses huge challenge this strategy. In work, we report novel and universal electrodeposition strategy rationally synthesize self-supporting electrode. utilization ammonium fluoride helps modulate not only morphology CoP, but also synchronous formation an anion-modified structure, leading excellent performance. optimal F-CoP/CF exhibits small potentials -90 mV 41 at 1 A cm-2, high stability low Tafel slopes 28 dec-1 3.26 for HER HzOR, respectively. efficient stable activity can be further confirmed in anion-exchange membrane hydrazine-assisted water electrolyzer (0.49 V cm-2). Utilizing density functional theory calculations, optimized adsorption energy molecules intermediates well rate-determining step HzOR are demonstrated F-CoP.

Self‐Supported Fe‐Based Nanostructured Electrocatalysts for Water Splitting and Selective Oxidation Reactions: Past, Present, and Future

Advanced Energy Materials, Год журнала: 2024, Номер 14(15)

Опубликована: Март 10, 2024

Abstract Electrochemical water splitting plays a vital role in facilitating the transition towards sustainable energy future by enabling renewable hydrogen (H 2 ) production, storage, and emission‐free transportation. Developing earth‐abundant electrocatalysts with outstanding overall water‐splitting performance, excellent catalytic activity, robust long‐term stability is highly important practical application of electrolysis. Self‐supported have emerged as most appealing candidate for H production due to their increased active site loading, rapid mass charge transfer, strong interaction underneath conducting support. Additionally, these also provide enhanced reaction kinetics stability. Here, comprehensive review recent progress developing self‐supported Fe‐based selective oxidation reactions presented examples oxyhydroxides, layered double hydroxides, oxides, chalcogenides, phosphides, nitrides, other Fe‐containing electrocatalysts. A historical development synthesis provided, an emphasis on various deposition methods choice substrates considering large‐scale commercial applications. An overview mechanistic understanding approaches are presented. Finally, challenges opportunities associated applications alternative discussed.
