Example Embodiment
[0028] Example 1ZnTiO 3 / TiO 2 -Organic pillared montmorillonite CTAB18
[0029] (1) Organic pillared montmorillonite CTAB18 : After smashing the montmorillonite mineral, it is passed through a 200-mesh sieve and placed in a drying oven at 60°C for 2 days, which is the montmorillonite raw soil; take 20 parts by weight of the montmorillonite raw soil and press the montmorillonite raw soil and distilled water The mass ratio is 1:10, the original soil is dispersed in water to form a suspension slurry; afterwards, octadecyltrimethylammonium bromide (octadecyltrimethylammonium bromide) is added in an amount equivalent to 1 times the cation exchange capacity (CEC) of the montmorillonite original soil. CTAB18), stir for 2h under the constant temperature of a water bath at 60℃, and let it stand overnight. The product is washed with deionized water to no Br - (In Ag + Test) Exist, dry at 90℃, fully grind and pass through 200 mesh sieve, then organic pillared montmorillonite can be obtain
Example Embodiment
[0038] Example 2ZnTiO 3 / TiO 2 -Organic pillared vermiculite CTAB12
[0039] (1) Organic pillared vermiculite CTAB12 : The vermiculite mineral is crushed and passed through a 200-mesh sieve, and placed in a drying oven at 80°C for 1 day to become vermiculite raw soil; take 20 parts by weight of vermiculite raw soil, and the mass ratio of raw soil to distilled water is 1:10 Ratio, disperse the original soil in water to form a suspension slurry; then add dodecyltrimethylammonium bromide (CTAB12) equivalent to twice the amount of the vermiculite original soil cation exchange capacity (CEC) in a 60℃ water bath Stir at a constant temperature for 2 hours, and place overnight. The product is washed with deionized water to no Br - (In Ag + Test) Exist, dry at 90℃, fully grind and pass through 200 mesh sieve, then organic pillared vermiculite can be obtained CTAB12 .
[0040] (2) ZnTiO 3 / TiO 2 The preparation is as step (2) in Example 1.
[0041] (3) ZnTiO 3 / TiO 2 -Organic pillared
Example Embodiment
[0042] Example 3ZnTiO 3 / TiO 2 -Organic pillared rectorite CTAB14
[0043] (1) Organic pillared rectorite CTAB14 : The rectorite mineral is crushed and passed through a 200-mesh sieve, and placed in a 70°C drying oven for 1.5 days to become rectorite raw soil; take 20 parts by weight of rectorite raw soil, according to the mass ratio of raw soil to distilled water Disperse the original soil in water at a ratio of 1:10 to form a suspension slurry; then add tetradecyltrimethylammonium bromide (CTAB14) equivalent to 0.5 times the amount of rectorite original soil cation exchange capacity (CEC), Stir in a water bath at 60°C for 2 hours and place overnight. The product is washed with deionized water to no Br - (In Ag + Test) Exist, dry at 90℃, fully grind and pass through 200 mesh sieve, then organic pillared rectorite can be obtained CTAB14 .
[0044] (2) ZnTiO 3 / TiO 2 The preparation is as step (2) in Example 1.
