Gas-Liquid Interfacial Plasma engineering under dilute nitric acid to improve hydrophilicity and OER performance of nickel foam
文献摘要：
The world has been moving rapidly to find new eco-friendly energy sources.Water electrolysis consists of two reactions of Oxygen Evolution Reaction(OER)and Hydrogen Evolution Reaction(HER),whereas the OER is considered the rate-limiting step.The most commercialized electrode for OER in the alkaline electrolyte is Ni foam,but its original surface is hydrophobic.It is possible to accelerate the adsorption and desorption process of reactants and products during OER by adding hydrophilic functional groups such as-OH on the surface of Ni foam.In this study,a novel Gas-Liquid Interfacial Plasma(GLIP)engineering at room temperature was success-fully applied to modify the Ni foam surface dilute(1 M)HNO3 solution.At a current density of 400 mA cm-2,GLIP-treated Ni foam electrodes at 1 M HNO3 concentrations showed OER overpotentials of 458 mV.Among all,GLIP with 1 M HNO3 treatment of 30 min showed 129 mV less overpotential than the nickel foam before treatment.In summary,GLIP can be justified as an environmentally friendly and efficient surface treatment to improve the wettability and OER performance of Ni-based electrodes in water electrolysis.
