Metallic ion doped nano TiO2 transparent photo-catalytic emulsion and preparation method thereof

Abstract

The metal ion mixed with TiO2 transparent optical catalyst lotion features in 0. 5-10% TiO2, mixed with V, Tin, Zn, Fe, OP emulsifier 1-10% with the rest being water, comprising a making of titanic chloride water solution, hydrolysis to generate TiO2+, VO3+, Sn4+, Zn2+, Fe3+ or Ce3+ compound oxidation deposit, low temperature complexing, hydrolysis to get the metal mixed nanometer TiO2 transparent catalyst lotion. It uses cheap titanium tetrachloride and ammonium vanadate, white copperas, Fe2cl3,tin tetrachloride as the inorganic material, using low temperature complex hydrolysis to allow higher ability to mix, expanding spectral response zone. Its maximum advantage is the direct use of sun light or fluorescent lamp, realizing complete degradation of organic pollutants, improving the speed and efficiency of photochemical catalysis and degradation for environmental purification.

Description

technical field

[0001] The invention relates to a metal ion doped nano TiO 2 The transparent photocatalyst emulsion and its preparation method belong to the technical field of chemical synthesis and refining. Background technique

[0002] In recent years, a large number of synthetic materials and automobile manufacturing materials used in home decoration have caused great pollution to the living environment. Photocatalytic oxidation treatment technology, as a new type of pollution control method, can finally degrade pollutants into non-toxic and harmless Inorganic small molecules can thoroughly purify the environment. Nano-scale titanium dioxide photocatalyst, which is widely studied at present, is the most potential photocatalytic oxidation material in the world today, and can be applied to deal with various environmental problems. However, nano-titanium dioxide powder is prone to agglomeration during storage, and it is difficult to recycle during photocatalysis. Because ...
