Superior photocatalytic performance of ZnMoO₄/Ag₂WO₄ for degradation of trimethoprim and methylene blue

ABSTRACT

In the present work, ZnMoO₄/Ag₂WO₄ nanocomposite was synthesized via facile hydrothermal and chemical precipitation method for determination of photocatalytic performance on organic contaminants such as methylene blue and trimethoprim. The synthesized nano-photocatalyst was characterized using various instrumental techniques. Photocatalytic degradation of methylene blue and trimethoprim by the samples was realized under UV light irradiation. The obtained results demonstrated that photocatalytic degradation of methylene blue by ZnMoO₄/Ag₂WO₄ was 99.6% in 30 min. The bare ZnMoO₄ produced 57.8% and Ag₂WO₄ produced 76.7% photocatalytic degradation of methylene blue in 60 min. The synthesized ZnMoO₄/Ag₂WO₄ nanocomposite, about which there is little information on remediation of organic pollutants, had possessed the outstanding photocatalytic degradation performance on methylene blue and trimethoprim due to pseudo first order kinetic.
