Herein we report heterogeneous catalyst MgZrO3@Fe2O3@ZnO nanoparticles by sol-gel approach. They were characterized by UV-visible diffused reflectance spectroscopy (UV-DRS), X-ray diffraction (XRD), Scanning electron microscopy (SEM), Energy dispersive x-ray analysis (EDAX), and High-resolution transmission electron microscopy (HRTEM) and selected area diffraction. This characterization confirmed the structure of MgZrO3@Fe2O3@ZnO and also confirmed excellent photocatalytic activity for the decolorization of Nigrosin dye under ambient conditions. The 96±0.5 % degradation was observed within 60 min using 20 ppm Nigrosin dye solution with 0.2 g of MgZrO3@Fe2O3@ZnO core-shell nanoparticles. A mechanistic approach for photodegradation of dye was established by Liquid chromatography-mass spectrometry (LCMS) with the identification of numerous smaller fragment molecule UR - https://www.jwent.net/article_253461.html L1 - https://www.jwent.net/article_253461_59a326b264be63bbb9a168e68fbf9525.pdf ER -
