Facet Engineering of Advanced Electrocatalysts Toward Hydrogen/Oxygen Evolution Reactions

Nano-Micro Letters, Journal Year: 2023, Volume and Issue: 15(1)

Published: Feb. 16, 2023

The electrocatalytic water splitting technology can generate high-purity hydrogen without emitting carbon dioxide, which is in favor of relieving environmental pollution and energy crisis achieving neutrality. Electrocatalysts effectively reduce the reaction barrier increase efficiency. Facet engineering considered as a promising strategy controlling ratio desired crystal planes on surface. Owing to anisotropy, with different orientations usually feature facet-dependent physical chemical properties, leading differences adsorption energies oxygen or intermediates, thus exhibit varied activity toward evolution (HER) (OER). In this review, brief introduction basic concepts, fundamental understanding mechanisms well key evaluating parameters for both HER OER are provided. formation facets comprehensively overviewed aiming give scientific theory guides realize dominant planes. Subsequently, three strategies selective capping agent, etching coordination modulation tune summarized. Then, we present an overview significant contributions facet-engineered catalysts HER, OER, overall splitting. particular, highlight that density functional calculations play indispensable role unveiling structure–activity correlation between plane catalytic activity. Finally, remaining challenges provided future prospects designing advanced electrocatalysts discussed.

A Review of Transition Metal Boride, Carbide, Pnictide, and Chalcogenide Water Oxidation Electrocatalysts

Chemical Reviews, Journal Year: 2023, Volume and Issue: 123(23), P. 12795 - 13208

Published: Nov. 15, 2023

Transition metal borides, carbides, pnictides, and chalcogenides (X-ides) have emerged as a class of materials for the oxygen evolution reaction (OER). Because their high earth abundance, electrical conductivity, OER performance, these electrocatalysts potential to enable practical application green energy conversion storage. Under potentials, X-ide demonstrate various degrees oxidation resistance due differences in chemical composition, crystal structure, morphology. Depending on oxidation, catalysts will fall into one three post-OER electrocatalyst categories: fully oxidized oxide/(oxy)hydroxide material, partially core@shell unoxidized material. In past ten years (from 2013 2022), over 890 peer-reviewed research papers focused electrocatalysts. Previous review provided limited conclusions omitted significance "catalytically active sites/species/phases" this review, comprehensive summary (i) experimental parameters (e.g., substrates, loading amounts, geometric overpotentials, Tafel slopes, etc.) (ii) electrochemical stability tests post-analyses publications from 2022 is provided. Both mono polyanion X-ides are discussed classified with respect material transformation during OER. Special analytical techniques employed study reconstruction also evaluated. Additionally, future challenges questions yet be answered each section. This aims provide researchers toolkit approach showcase necessary avenues investigation.
