- W4309079834 abstract "To develop a high-efficient catalyst for oxygen evolution reaction (OER), creating high current densities at low overpotentials is highly desirable. Herein, an effective and low cost catalyst based on anchoring Ni3S2/WO3 nanocomposite over the reduced graphene oxide (rGO) was hydrothermaly synthesized and characterized using spectroscopic and microscopic techniques, and its electrochemical parameters as a suitable OER electrocatalyst in alkaine media at surface of nickel foam (NF) was studied. Electrochemical measurements showed that, anchored Ni3S2/WO3 on rGO increased ionic conductivity, surface area, active sites of electrocatalyst, decreased the charge transfer resistance and exhibit the overpotential of 280 mV to reach 50 mA cm−2, with a Tafel slope of ∼48 mV/dec and good stability for the OER in comparison to other tested composites. As a result, this catalyst can work at high and low current densities for a long time." @default.
