Sulfonated reduced graphene oxide encapsulated perovskite-type ErCoFe oxide nanoparticles for efficient electrochemical water oxidation.

Perovskite oxides play a vital role as electrocatalysts in water oxidation due to their flexible and unique electronic structures. In this work, Er-based perovskites ErCoFeO ( = 0.0, 0.

Electrocatalytic water oxidation by a Ni(ii) salophen-type complex.

A new mononuclear Ni(ii) complex, NiL (1), was synthesized from the reaction of Ni(OAc)·4HO and salophen-type NO-donor ligand, HL (where HL = 2,2'-((1,1')-((4-chloro-5-methyl-1,2-phenylene)bis(azanylylidene))bis(methanylylidene))diphenol), in ethanol. The obtained complex was characterized by elemental analysis, spectroscopic techniques and single crystal X-ray analysis. The complex was studied as a water oxidizing catalyst and its electrocatalytic activity in the water oxidation reaction was tested in 0.
