Interface Engineering of NiS and Zeolitic Imidazolate Framework-67: Enhancing the Overall Electrochemical Water Splitting.

Recent progress on a metal-free and highly efficient electrocatalyst for the production of oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) during the water electrolysis process makes it highly suitable to produce clean and sustainable renewable hydrogen energy. The electrocatalyst of NiS/ZIF-67 composite prepared by a facile precipitation method and which exhibits excellent catalytic activity for overall OER and HER performances with a small Tafel slope (92.1 and 61.

CeO nanospheres incorporated with BiMoO/g-CN enhanced photocatalysis towards environmental pollutant Rhodamine B removal.

We have adopted a novel CeO/BiMoO/g-CN-based ternary nanocomposite that was synthesized via hydrothermal technique. The physiochemical characterization of as-prepared samples was examined through various analytical techniques such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy TEM, photoluminescent spectra (PL), X-ray photoelectron spectroscopy (XPS), Brunauer-Emmett-Teller (BET), and ultraviolet diffuse reflectance spectroscopy (UV-DRS) technique. In addition, the photocatalytic performance was carried out by degradation of Rhodamine B dye under visible light irradiation using this nanocatalyst.
