Abstract The chainmail catalyst by encapsulating an active species within the carbon support is a well‐established concept to endorse extraordinary stability for catalytic reactions under harsh conditions. Conventional catalysts inevitably suffer from poor accessibility sites, leading extra voltage compensate sluggish diffusion kinetics in electrocatalysis. Herein, naturally abundant wood material converted into monolithic electrocatalyst cobalt nanoparticles N‐doped carbonized wood. Such employed directly as electrode hydrogen evolution (HER), oxygen (OER), and monosaccharide oxidation (MOR) with benchmark performance. By coupling HER MOR, electrolyzer equipped allows production at current density of 100 mA cm −2 full cell only 1.36 V. design wood‐derived provides promising way fabricate robust electrocatalysts future value‐added chemicals.

The recent advances in nanomaterials have led to speculation about the effectivity of carbon quantum dots applied as electrocatalysts for water splitting. An insufficient amount research has been undergone into this proposed application, although CQDs exhibit great potential with rapid electron transfer rates, long-term stability and desirable morphologies. To evaluate various materials that could aid their application splitting, investigate environmentally conscious synthesis routes determine whether be considered commercial applications, numerous studies articles were collated obtain a comprehensive strategy processing analysing data. Further, investigating not only but metal alloy nanoparticles, along current uses other supporting they conjugated with, contributes significance work. Focusing on extrapolated results over potentials, densities production rates both hydrogen oxygen throughout electrolysis is utmost importance. Notably, exhibited low Tafel slopes (35–45 mV/dec), crucial traits such affirming electrocatalysts. Among nanoparticles investigated, suitable candidates conjugation identified. Collectively, data suggests CQD/metal nanoparticle enhance splitting process particularly underexplored realm production. However, it remains imperative perform experimental procedures substantiate proposition when feasible.

Constructing Amorphous‐Crystalline Interfacial Bifunctional Site Island‐Sea Synergy by Morphology Engineering Boosts Alkaline Seawater Hydrogen Evolution

Advanced Science, Год журнала: 2024, Номер 11(24)

Опубликована: Март 18, 2024

Abstract The development of efficient and durable non‐precious hydrogen evolution reaction (HER) catalysts for scaling up alkaline water/seawater electrolysis is highly desirable but challenging. Amorphous‐crystalline (A‐C) heterostructures have garnered attention due to their unusual atomic arrangements at hetero‐interfaces, exposed active sites, excellent stability. Here, a heterogeneous synthesis strategy constructing A‐C non‐homogeneous interfacial centers electrocatalysts on nanocages presented. Isolated PdCo clusters nanoscale islands in conjunction with Co 3 S 4 A‐C, functioning as bifunctional site “island‐sea” synergy, enable the dynamic confinement design metal atoms, resulting HER catalytic activity durability. hierarchical structure hollow porous nanoclusters, along large surface area multi‐dimensional boundaries defects, provides catalyst abundant centers. Theoretical calculations demonstrate that combination regulates redistribution interface electrons effectively, promoting sluggish water‐dissociation kinetics cluster sites. Additionally, PdCo‐Co heterostructure exhibit outstanding seawater long‐term stability 100 h, which can be powered by commercial silicon solar cells. This finding significantly advances large‐scale production.
