Electrochemical water splitting is regarded as the most promising approach to produce hydrogen. However, sluggish electrochemical reactions occurring at anode and cathode, namely, oxygen evolution reaction (OER) hydrogen (HER), respectively, consume a tremendous amount of energy, seriously hampering its wide application. Recently, single-atom catalysts (SACs) have been proposed effectively enha...

The potential for generating green hydrogen by electrolysis (water splitting) has resulted in a substantial amount of literature focusing on lowering the current production cost hydrogen. A significant contributor to this high is requirement precious metals (namely Pt and Ir/Ru (oxides)) catalyse two main reactions involved electrolysis: evolution reaction (HER) oxygen (OER). Herein we overview...

Production of hydrogen from water electrolysis has stimulated the search of sustainable electrocatalysts as possible alternatives.

The “ligand effect” can be used as a novel strategy for enhancing the catalytic properties of metal clusters. Herein, we report the ligand effect of porphyrin derivatives on gold clusters (AuCs, size <2 nm) and gold nanoparticles (AuNPs, size >2 nm) in the electrochemical hydrogen evolution reaction (HER) at pH 6.7. The current density of porphyrin face-coordinated AuCs at 0.4 V vs. reversible ...
