In situ growth of Prussian blue analogue-derived Fe-doped NiS on Ni(OH)₂ for efficient hydrogen evolution reaction

Abstract

The energy industry is placing more and more emphasis on the need for effective and affordable electrocatalysts for hydrogen evolution reactions (HER). In this work, an iron-doped NiS/Ni(OH)2/CC composite material...

A low-content CeOx dually promoted Ni3Fe@CNT electrocatalyst for overall water splitting

“…Exploration of green renewable hydrogen energy has been triggered due to the increasing energy crisis and environmental pollution that are caused by the combustion of traditional fossil fuels. Among those clean and efficient energy-conversion technologies, [1][2][3][4][5] electrocatalytic water splitting has attracted wide attention owing to its potential for convenient large-scale application and sustainability. 6 Generally, electrocatalytic water splitting occurs in two core half-reactions: the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER), both of which have sluggish reaction kinetics and are highly dependent on high-performance but precious electrocatalysts with lower overpotentials and accomplish favorable energy-transfer efficiency for activation.…”

Self‐Supported Earth‐Abundant Carbon‐Based Substrates in Electrocatalysis Landscape: Unleashing the Potentials Toward Paving the Way for Water Splitting and Alcohol Oxidation

“…115 (𝜼10) 74 [294] 1.0 m KOH 75 (𝜼10) 71 [294] Sulfur anion-assisted completely reconfigured MnO x (R-S-MnO x -CC) Carbon cloth 0.5 m H 2 SO 4 43 (𝜼10) 51.61 [295] Self-supported nanoarray MoO 2 @Ni 2 P on carbon paper (MoO 2 @Ni 2 P/CP) [300] electrode performance. Thereby, it is a prerequisite to fabricate highly stable and electrocatalytically functional binder-free electrodes that could successfully safeguard the demand for water electrolysis as well as mitigate the existing bottleneck of powder catalysts.…”
