Abstract:
Recently, the concerns about depletion of fossil fuels and also the environmental pollution arisen from burning of them have driven scientists to quest for clean and sustainable energy resources. Some advantages of hydrogen have made it as an alternative energy resource to fossil fuels. Electrochemically splitting of water is considered as one of the main techniques to produce high-purity hydrogen. Fabrication of cost-effective electrocatalysts for oxygen evolution reaction (OER) in a water splitting process is vital for large-scale practical applications. Herein, we present an affordable and straightforward method for synthesis of NiO nanoparticles supported on Ni foam for oxygen evolution reaction (OER). A single-step annealing process is carried out at the different temperatures to achieve an optimal temperature, at which an electrocatalyst with a tailored morphology and high electrocatalytic activity is obtainable. The best electrocatalytic activity is showed by the electrode fabricated at 400 °C, which delivers current density of 10 mA/cm2 at 1.59 mV potential versus reversible hydrogen electrode (RHE) under alkaline condition. Various material characterization tests accompanied by electrochemical measurements are employed to clarify the cause of the excellent electrocatalytic activity of the electrode fabricated at 400 °C.
