Synthesising nanocomposite Co2SnO4@rGO for peroximonosulphate activation in a hybrid ozonation system to effectively degrade cefalexin from wastewater.

Abstract

This study successfully developed Co₂SnO₄@rGO nanocomposites at various composite ratios of Co₂SnO₄ and rGO using the sol-gel method. These nanocomposites were then used as heterogeneous catalysts to activate PMS in the heterogeneous catalytic oxidation of Co₂SnO₄@rGO/PMS as well as the hybrid ozonation system O₃/Co₂SnO₄@rGO/PMS to degrade cefalexin (CFX)...
