Preparation method of superparamagnetic iron [email protected]@cadmium sulfide nanocore-shell structure material and its use. This patent uses SiO as the interface transition medium to connect superparamagnetic FeO nanoclusters and CdS nanosemiconductor [email protected]@CdS double core-shell structure nanomaterials with uniform size and uniform dispersion were successfully prepared. This double core-shell structure nanomaterial not only has excellent optical properties, but also can be used in complex reactions through a simple magnetic attraction operation.Recovery and separation. The synthesis method used in this patent is not only simple to operate, avoids the harsh reaction conditions of high temperature and high pressure, but also effectively eliminates the mismatch between FeO and CdS crystal planes, and the double core-shell structure has good morphology and dispersion.In addition, the prepared [email protected]@CdS core-shell nanomaterials can be successfully applied to the photocatalytic degradation of Rhodamine B.
