? 2021 Elsevier B.V.The research work demonstrates the facile fabrication of nickel molybdates (NiMoO4) nanocatalyst via greener approach using moringa oleifera extract as chelating agent. The phase and crystalline structure, functional groups, morphology were characterized using characterization tools. The XRD patterns confirms the monoclinic phase structure of α-NiMoO4 with the crystallite size of ~18 nm. The existence of Ni 2p, Mo 3d and O1s energy levels characteristics in the synthesized nanocatlayst was determined from the XPS analysis. Then the prepared nanocatalyst (α-NiMoO4) used as active material to degrade the methylene blue (effluent dye) under visible light and solar radiation. The photo-degradation efficiency of MB achieved to be 91% over the optimal nanocatalyst (NiMoO4) under solar radiation condition over 2 h and 81% for visible light under the same condition. Pseudo first order reaction rate constants of NiMoO4 for both visible light and solar light irradiation are determined to be 0.01387 min?1 and 0.01902 min?1, respectively.
