[0011] Example 1
[0012] The loaded nano composite oxide environmental purification material of the present invention uses diatomaceous earth and zeolite as carriers, and supports nano TiO 2 , Nano ZnO and Nano CeO 2 Among them, diatomaceous earth and zeolite are 70% of the total mass of the material, and nano-oxides are 30% of the total mass of the material; the mixing ratio of diatomaceous earth and zeolite is diatomite: zeolite = 1:1 by mass ratio, The mixing ratio of nano-oxide is TiO by mass ratio 2 :ZnO:CeO 2 =1:0.5:0.5.
[0013] The preparation method steps are as follows:
[0014] 1) Pass the diatomaceous earth and zeolite through a 100 mesh sieve, take 350g of diatomaceous earth and 350g of zeolite under the sieve, soak in 5000g of 5% hydrochloric acid for 3 hours, take it out and wash with distilled water 3 times, and dry at 90℃ After 2 hours, calcined at 200°C for 3 hours, take out and cool, and obtain the carrier for later use.
[0015] 2) Add 275g zinc nitrate Zn(NO ...
