Problems solved by technology

Zirconium phosphate is a common loading material that can be used as a catalyst carrier, but its general loading mechanism is by directly covering the surface of the carrier, and this contact is physical contact, which is easy to fall off and cause catalyst loss

Abstract

The invention discloses a preparation method of a plate like zirconium phosphate loaded indium phosphate catalyst. The preparation method comprises the following steps: dissolving zirconium chloride into water to prepare a zirconium chloride solution with the concentration of 0.1-0.5 mol / L, taking the solution as an aqueous phase, stirring TrionX-100, n-butyl alcohol, cyclohexane and the aqueous phase at the ratio of 1:(2-20):(2-40):(0.2-0.4) to prepare a microemulsion, adding an indium chloride solution dropwise while stirring the microemulsion, dropping a sodium triphosphate solution after finishing adding the sodium triphosphate dropwise, continuing to stir after finishing dropping, finally centrifugally separating, washing a solid with ethyl alcohol, and drying in vacuum to obtain the plate like zirconium phosphate loaded indium phosphate catalyst.

Description

technical field [0001] The invention relates to the technical field of sewage treatment in environmental protection, in particular to a preparation method of a plate-shaped zirconium phosphate-supported indium phosphate catalyst. Background technique [0002] Traditional water treatment methods have problems such as low efficiency, high cost, and secondary pollution, and sewage treatment has not been well resolved. The development and application of nanotechnology is likely to completely solve this problem. TiO was discovered in 1972 2 High oxidation activity, good chemical stability, non-toxic to the human body, low cost, no pollution, wide application range, so it is the most important, but TiO 2 The bandgap width is large (such as anatase TiO 2 The forbidden band width Eg=3.2eV), can only absorb the light in the ultraviolet region (wavelength less than 387nm), and the utilization efficiency of solar energy is low. [0003] Semiconductor photocatalysis is one of the mo...
