Plant based-biosynthesized silver doped zinc oxide for effective sonocatalytic degradation of malachite green: Characterizations and optimization studies

Sonocatalytic performance of silver doped zinc oxide (Ag-ZnO) nanoparticles synthesized using Clitoria ternatea Linn extract was optimized for the first time in the degradation of malachite green (MG) by using response surface methodology (RSM). A central composite design (CCD) model was successfull...
