Embodiment 1
[0027] Choose C content greater than 90%, specific surface area greater than 1000m 2 / g of powdered activated carbon or 20 grams of granular activated carbon, after drying at 150-170 ° C, ball milled in a dry state for 6 hours to obtain powdered activated carbon with a particle size of 0.1-1 micron, and then mix the ball-milled powdered activated carbon to 1000 grams In the solution, the solution is an alcohol amine aqueous solution of 8%% by volume, and then ball milled in a wet state for no less than 10 hours, and after standing for 24 hours, the suspension is taken for subsequent use. At this time, the diameter of the activated carbon particles in the suspension is less than 1 micron; the alcohol amine aqueous solution is one or a mixture of monoethanolamine, diethanolamine, triethanolamine or methyldiethanolamine.
[0028] Dissolve 1 g of ammonium metavanadate, 2 g of titanium nitrate, and 5 g of aluminum nitrate into 72 g of suspension after mixing, adjust the pH to 4-4....
