A mixed Sulfur-doped zinc oxide-nickel oxide nanocomposite electrocatalyst for oxygen evolution reaction (OER) was prepared. By hydrothermal method, we prepared a high-efficiency OER electrocatalyst doped with zinc oxide and nickel oxide. By applying different characterizations, the material was proven to be a new phase of (S-doped-ZnO-NiO). S-doped ZnO-NiO, ZnO-NiO did not show excellent performance. At 10 mA cm− 2, the generation potential of OER is 1.45 V and that of HER is -0.04 V. This unique morphology results in better OER performance of 240 mV at 10 mA cm− 2 in the KOH electrolyte, and similarly, the S-doped ZnO-NiO shows us excellent long-term stability in alkaline media with a small Tafel slope (77 mV dec− 1). S-doped ZnO-NiO hybrid catalysts offer great potential for electrochemical devices due to their low cost and high activity. we have successfully constructed an electrocatalyst with the dual functions of HER and OER, which can achieve efficient water splitting.

“…The broad applicability of nanoscale NiO relies on the material's high surface area and interesting properties, including chemical, electrochemical, and catalytic properties, which are not present in the bulk material. To meet the high demand for this nanoscale material, several synthetic methods have been developed based on hydrothermal,,,, sol‐gel,,, hot‐injection, co‐precipitation, microwave,, reverse micelle templated, electrochemical and pulsed laser ablation techniques, as well as techniques based on complex formation with an organic moieties and successively their thermal decomposition . Among the mentioned methods, the latest one is well known as scalable with high yield.…”

Influence of Pamoic Acid as a Complexing Agent in the Thermal Preparation of NiO Nanoparticles: Application to Electrochemical Water Oxidation

We developed a thermal decomposition method for preparing NiO nanoparticles (NiONPs) using disodium salt of pamoic acid (Na2PA) as a complexing agent and Ni(NO3)2⋅6H2O as a nickel precursor. Prior to thermal decomposition, Ni(NO3)2⋅6H2O was mixed with Na2PA in ethanol, and the ethanol was evaporated succesively. The dried reaction mass was characterized using Fourier transform infrared spectroscopy, X‐ray photoelectron spectroscopy, and thermal gravimetric analysis. Thermal decomposition was then performed in air to obtain the NiONPs. The role of Na2PA in the synthesis of NiONP was evaluated by preparing NiONPs according to the protocol described above without the addition of Na2PA. The X‐ray diffraction data indicated that crystalline NiO (bunsenite, cubic crystal system) formed with or without Na2PA; however, field emission scanning electron microscopy images showed that smaller monodisperse NiONPs formed only with the addition of Na2PA. Without Na2PA, the obtained NPs were quite large and polydisperse. The sizes of the NiONPs prepared in the presence of Na2PA were determined using transmission electron microscopy imaging to be 19.1 ± 3.2 nm. The electrocatalytic activity of the NiONPs toward water oxidation under alkaline conditions was evaluated by immobilizing the NPs onto an in‐house prepared filter paper derived carbon electrode, and compared.
