Self-assembly of functionalized Echinops-like Rh porous nanostructure electrocatalysts for highly efficient seawater splitting

Abstract

Although water electrolysis provides a promising technology for global hydrogen economics, high efficient electrocatalysts are required to boost the sluggish kinetics of both hydrogen evolution reaction (HER) and oxygen evolution...

Ni Single Atoms and Ni Phosphate Clusters Synergistically Triggered Surface‐Functionalized MoS2 Nanosheets for High‐performance Freshwater and Seawater Electrolysis

“…Figure 5g evidences the Ni SA ‐Ni Pi /MoS 2 NSs (+, −) require a low cell voltage at 10 mA cm −2 that is comparable or even lower to the previously reported catalysts for electrochemical overall water splitting in freshwater, [ 33,37,63–70 ] mimic seawater, [ 71–78 ] and natural seawater. [ 77,79–83 ] Based on our aforementioned findings, Ni SA ‐Ni Pi /MoS 2 NSs material is an efficient binder‐free bifunctional catalyst having a significant potential for improving the industrial production efficiency of green hydrogen energy via electrocatalytic water splitting.…”

Rational Assembly of the NiMoP/NiCoZn Heterostructure Electrocatalyst for the Hydrogen Evolution Reaction at High Current Densities

“…Although efficiencies at low current density have rapidly increased, functional electrodes for high-speed water splitting remain limited . Various methods have been adopted to solve the aforementioned problem, such as constructing heterostructures, doping elements, designing nanostructures, and fabricating defects . Among these strategies, heterojunction construction has been confirmed to be an effective route for adjusting the surface electron structure of electrocatalysts, thus promoting the HER performance.…”

Time-resolved XAS studies reveal sequential oxidative–reductive formation of Na-doped iridium oxide films with enhanced bio-stimulating performance

“…The fabrication of iridium oxide has been explored for several decades in applications including water splitting and pseudocapacitors. [1][2][3][4][5][6][7][8][9] It is because the iridium oxide is known as a conductive oxide with superb chemical inertness and electrocatalytic activity. Recently, owing to its impressive biocompatibility, the iridium oxide has been considered as a bio-stimulating electrode in implantable bio-electronics whose function is to provide electrical charges to stimulate neurons for the mitigation or remedy of neuronal disorders.…”
