CuS nanoparticles with superior sonocatalytic performance in degradation of dye

Abstract

In this manuscript, sonocatalytic catalytic efficiency of CuS nanoparticles (NPs) is analysed for degradation of dye. CuS NPs acts as equally outstanding sonocatalyst for both cationic and anionic dye. In the process of degradation of both dyes, the catalytic efficiency of CuS NPs is examined by studying the change in absorption peak of dye by using UV–visible spectrophotometer. The consequence of factors like dopant dose, initial pH of reaction mixture and starting dye concentration on sonocatalytic efficiency of CuS NPs was explored. CuS NPs demonstrated brilliant degradation of both dyes in presence of ultrasonic waves. It is seen that Kinetics followed by degradation of dye process is pseudo First order. The velocity constant for both dyes were productively calculated. Reusability experiments of CuS NPs were conducted to check their utility. Value of rate constant for sonocatalysis is high.
