synthesis and characterization of ni–co ferrite composite oxide nanocrystals as a reactive photocatalyst of phenol in aqueous solutions

The ni–co ferrites composites have been successfully synthesized by hydrothermal process.the morphology, microstructure and electromagnetic properties were investigated by fourier transform infrared spectrum (ft-ir), x-ray diffraction (xrd), scanning electron microscope (sem), transmission electron microscope (tem), network analyzer and vibrating sample was successfully synthesized by copreciptation method from a three salts: mncl2, cocl2 and fecl3. the synthesised composite could be the potential candidates for degradation of phenol from waste waters. in this study, a high sensitive electrochemical sensor for phenol was established based on graphene oxide carbon paste electrode. the proposed sensor exhibited strong enrichment effect on phenol and gave superior catalytic activity towards the electro-oxidation of phenol.
