Harnessing MnMoO4 Nanoparticles for Eco-Conscious Effluent Degradation and Catalytic Applications

In order to improve MnMoO ₄ photocatalytic capabilities for the degradation of hazardous wastewater and organic catalysis applications, this work proposes a green production method. Precursor solutions of molybdenum and manganese for the produced MnMoO ₄ are prepared as part of the synthesis process. The ability of the synthesized catalyst to degrade hazardous effluents in the presence of visible light is demonstrated by photocatalytic testing. The performance of MnMoO ₄ for organic catalysis compounds and environmental remediation can be further enhanced by optimizing the photocatalytic settings and synthesis parameters. This is followed by the solution combustion method and calcination process. Phase purity, morphology, and functional groups are confirmed by characterization methods such as X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), ultraviolet (UV), photoluminescence (PL), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). By tackling environmental contamination and developing sustainable catalytic processes, this study advances the development of effective photocatalytic materials. Under visible light irradiation, Rose Bengal (RB) was subjected to photocatalytic degradation in an aqueous media. 91% degradation rate was attained while researching Rose Bengal dye's photocatalytic activity. The β-enaminone synthesis reaction was examined to determine if the produced MnMoO ₄ catalyst could catalyse it. Aniline and dimedone were used as model reactants in optimization studies for the reaction, and TLC was used to detect the emergence of contaminants.
