Synergistic coupling of FeNi3 alloy with graphene carbon dots for advanced oxygen evolution reaction electrocatalysis

Electronic and architecture engineering of hammer-shaped Ir–NiMoO4-ZIF for effective oxygen evolution

“…[1][2][3] Among them, hydrogen has received great interest as one of the most promising substitutes because of its high energy density and near-zero carbon emission. [4][5][6] Electrochemical water splitting, including the anodic oxygen evolution reaction (OER) and cathodic hydrogen evolution reaction (HER), has aroused great interest for hydrogen production. However, the HER is seriously restricted by the sluggish kinetics of the OER, due to the complicated reaction process.…”

Engineering transition metal catalysts for large-current-density water splitting

“…By developing advanced electrocatalysts toward overall water splitting, the intermittent electrical energy generated from renewable solar and wind energy can be converted into hydrogen energy. 1,2 Unfortunately, despite the great advantages of overall water splitting, the practical applications of electrocatalytic water electrolysis are greatly hampered by the large overpotentials of the two half reactions: [3][4][5][6] the anodic oxygen evolution reaction (OER) and the cathodic hydrogen evolution reaction (HER). In order to lower the overpotentials of both the HER and OER, many advanced electrocatalysts have been successfully developed.…”

Electrospun one-dimensional electrocatalysts for boosting electrocatalysis

“…Recent years have witnessed the rapid development of cost-effective electrocatalysts, such as carbon-based materials, 33,34 transition metal compounds, 35,36 MOFs, [37][38][39] and COFs. 40,41 Although great efforts have been made, a large activity gap still exists when compared with noble metal catalysts.…”
