Synthesis and sonocatalytic performance of bimetallic AgCu@MWCNT nanocatalyst for the degradation of methylene blue under ultrasonic irradiation

Abstract

In this study, AgCu@MWCNT nanocatalyst was synthesized by following a series of physicochemical hydrothermal processes. The obtained catalysts of AgCu@MWCNT were characterized by advanced spectroscopic methods. AgCu@ MWCNT nanocatalyst used for degradation of MB was investigated under ultrasonic irradiation, and AgCu@MWCNT nanocatalyst exhibited an excellent sonocatalytic activity function. The effects on sonocatalytic activity were investigated with various experimental parameters. Percent degradation of MB after sonocatalytic activity was found to be 90.2% for 60 min. Findings showed that in the presence of AgCu@MWCNT nanocatalysts, OH and O2% - radicals were determined to be the main molecules in the degradation of MB under sonocatalytic conditions. The intermediate by-products of the paint formed in the degradation process were characterized by GC-MS technique. Overall, based on the results, AgCu@MWCNT nanocatalysts were detected as an effective nanocatalyst for degradation of MB using the ultrasonic process method.
