The invention discloses a preparation method of a ZnO/CNTS nano-photocatalytic composite material, belonging to the technical field of oxide composite nano-materials. Salt-type anionic surfactant; uniformly mix the precursor solution for generating ZnO particles and carbon nanotube dispersion, and then apply an alternating electric field during the heating process to obtain ZnO/CNTS nanophotocatalytic composite materials; then separate and purify. The external alternating electric field of the invention reduces the agglomeration of the carbon nanotubes, makes the carbon nanotubes arrange in an orderly manner, improves the utilization efficiency of the carbon nanotubes, reduces the amount of the surfactant, and provides the production of ZnO/CNTS nanometer photocatalytic composite materials. new process. |
