Abstract
The present invention relates to a kit for water treatment, comprising: a photocatalyst including at least one of SnFe2O4, ZnFe2O4, CuFe2O4, Fe3O4, MnFe2O4 and NiFe2O4; and an active oxide. The present invention also relates to a method for manufacturing a photocatalyst and a use of the prepared photocatalyst.
Claims10
A kit for water treatment, comprising:
- a photocatalyst including at least one of SnFe2O4, ZnFe2O4, CuFe2O4, Fe3O4, MnFe2O4 and NiFe2O4;
- and
- an active oxide.
A method for manufacturing a photocatalyst, comprising the following steps:
- (A) dissolving a divalent metal precursor and an iron precursor in a first solvent to form a first precursor solution;
- (B) mixing a second solvent with the first precursor solution to form a first mixed solution, wherein the second solvent is miscible with the first solvent;
- (C) adding a third solvent into the first mixed solution to obtain a layered solution, wherein third solvent is located at an upper layer of the layered solution, and the first mixed solution is located at a lower layer of the layered solution;
- (D) stirring the layered solution for carrying the precursor solution from the first mixed solution into the third solvent to obtain a second mixed solution comprising a photocatalyst, wherein the photocatalyst includes at least one of SnFe2O4, ZnFe2O4, CuFe2O4, Fe3O4, MnFe2O4 and NiFe2O4;
- and
- (E) separating the photocatalyst from the second mixed solution through a centrifugation.
