Preparation method of cobalt ferrite conductive imprinting compound photocatalyst

The invention belongs to the technical field of the preparation of environmental materials, and particularly relates to a preparation method of a cobalt ferrite conductive imprinting compound photocatalyst. The preparation method comprises the following steps: pretreating MWCNTs (Multiwalled Carbon Nanotubes) to obtain acidified MWCNTs; dispersing Co(NO3)2.6H2O and Fe(NO3)3.9H2O into water for ultraphonic, then adding activated MWCNTs for the ultrasonic, and finally adding alkali, stirring and then carrying out hydro-thermal synthesis to obtain CoFe2O4/MWCNTs; adding 2-mercaptobenzothiazole to pyrrole-containing trichloromethane, adding a cross-linking agent and an initiating agent, adding a mixed solution to a CoFe2O4/MWCNTs solution with activated polyethylene glycol 4000, stirring for a period of time under an N2 atmosphere, and washing and drying to obtain a PPy/CoFe2O4/MWCNTs magnetic molecule imprinting photocatalyst.
