Degradasi Methyl Orange Secara Fotosonolisis Menggunakan Katalis ZnO/TiO2

Abstract

The present study focuses on the development of efficient nanophotocatalysts (pure and Gadolinium doped Zinc oxide) for the degradation of methyl orange dye in polluted water. Chemical co-precipitation technique was employed for the synthesis of target compounds using zinc acetate and gadolinium nitrate as metal precursors. The synthesized nanoparticles were characterized by various spectroscopic techniques namely X-ray diffraction, Fourier Transform infra red spectroscopy, Field emission scanning electron microscopy and energy dispersive X-ray spectroscopy. The synthesized pure and Gadolinium doped Zinc oxide nanoparticles were used as photocatalysts for the degradation of methyl orange dye under ultra-violet light irradiation. Doping of ZnO nanoparticles with Gadolinium has greatly increased its catalytic efficiency.
