Investigation of performance of magnetic Ni-Fe nanospinels supported on carbon quantum dots for remove of phenolic compounds from wastewater by catalytic wet peroxide oxidation (CWPO)

In this study, the process of phenol oxidation and related compounds as an example of industrial wastewater by catalytic wet oxidation with hydrogen peroxide (CWPO) magnetic nanospinels of nickel ferrite supported on carbon quantum dots were investigated. This catalyst was synthesized in a co-operation method without the need for hard conditions such as high temperature and high pressure as well as inaccessible devices. The structure and morphology of the synthesized catalysts were investigated using XRD, FT-IR and SEM techniques. XRD and FTIR indicated the formation of the catalyst. The results of the scanning electron microscopy (SEM) analysis indicated the formation of uniform distribution of particle size in the nanometer range. Then the optimal conditions for the experiments were determined.
