Developing an efficient and economical electrocatalyst for oxygen evolution reaction is the key challenge to renewable energy technologies. Metal selenides are attractive candidates electrocatalytic water oxidation because they provide suitable surface-active sites reaction. Herein, we report less explored hexagonal cobalt selenide (CoSe) preparation through facile environmentally benign one-st...

Developing oxygen evolution reaction (OER) electrocatalysts is essential to accomplish viable CO2 and water electrolysis. Herein, we report the fabrication OER performance of Ni-foam (NF)-immobilized Ni6 nanoclusters (NCs) (Ni6/NF) prepared by a dip-coating process. The Ni6/NF electrode exhibited high current density 500 mA/cm<sup>2</sup> for at an overpotential as low 0.39 V. durab...

Electrocatalysts for the oxygen evolution reaction (OER) are an important component transition from fossil to sustainable energy. Commercialization of cost-effective earth-abundant electrocatalysts is in large parts hindered by their degradation. In this short review, I identify common processes leading a decrease electrocatalyst activity, followed introduction staple methods determine degradat...

Hydroxyl radicals arising from the Fenton reagent remove metastable surface gold atoms (low coordinated high-energy surface atoms) on the Au surface, thus precluding the formation of stable oxides. The resultant smooth surface, upon hydroxyl-radical activation, electrocatalyzes oxygen evolution reaction in 0.1 M NaOH at overpotentials lowered by 190 mV @ 10 mA cm(-2).
