Oxygen vacancy-rich amorphous FeNi hydroxide nanoclusters as an efficient electrocatalyst for water oxidation
文献摘要：
In this work,a one-pot strategy is presented to directly synthesize amorphous FexNiy hydroxide nan-oclusters(denoted as ANC-FexNiy,＜2 nm)with oxygen vacancies induced by ionic liquids.The ANC-FexNiy catalyst presents abundant catalytic sites and high intrinsic conductivity.As such,the optimized ANC-Fe1Ni2 exhibits high activity in oxygen evolution reaction(OER)with a Tafel slope of 39 mV dec-1 and an overpotential of 266 mV at 10 mA cm-2.Notably,the optimized ANC-Fe1Ni2 shows an extraordi-narily large mass activity of 3028 A gF1eNi at the overpotential of 300 mV,which is～24-fold of commercial RuO2 catalyst.The superior activity of these FexNiy hydroxide nanoclusters is ascribed to(i)the amor-phous and distorted structure with abundant oxygen vacancies,and(ii)enhanced active site density by downsizing the ANC-FexNiy clusters.This strategy provides a novel route for enhancing OER electro-catalytic performance and highly encouraging for the future application of amorphous metal hydroxides in catalysis.
