The invention discloses a catalyst for natural light treatment of wastewater and a preparation method thereof. The invention loads a ferrous cobaltate FeCo 2 O 4 catalyst on a biomass carbon CF carrier to prepare a FeCo 2 O 4 -CF composite catalyst. Due to the large specific surface area of CF, the FeCo 2 O 4 catalyst can be adsorbed on its surface, which effectively improves the photon utilization rate and solves the particle agglomeration phenomenon caused by the small particle size of FeCo 2 O 4 . Compared with the FeCo 2 O 4 catalyst, the FeCo 2 O 4 ‑CF composite catalyst increases the use efficiency and catalytic performance, greatly reduces the loss rate, and increases the service life. The FeCo 2 O 4 ‑CF catalyst has high activity, is hardly soluble in water, has a long service life, is not easy to be poisoned, and is easy to recycle, and can be widely used in the environmental field of degrading pharmaceutical wastewater. At the same time, the particle size of FeCo2O4-CF prepared by the method of the present invention is easy to control, and can reach the order of microns or even millimeters, so that the FeCo2O4-CF composite catalyst is easier to separate and recover. |
