Embodiment 1

[0022] Add 2 grams of potassium titanate powder into 100 milliliters of deionized water, and stir evenly. 6 ml of phosphoric acid was added, and the pH of the solution was adjusted to 2 with ammonia. Afterwards, 0.08 g of silver nitrate was added under light-shielding conditions, and stirred to dissolve. It was then stirred for 30 hours in the dark. At the same time, 0.8 g of zirconium oxychloride octahydrate was added into 20 ml of deionized water, and stirred to dissolve. After the stirring in the dark, the zirconium oxychloride solution was added to the former solution, and the stirring was continued in the dark for 8 hours. After stirring, the precipitate was washed with deionized water until the pH of the washing solution was neutral, and then dried. Afterwards, it was fired at 800 degrees for 2 hours to obtain the target silver-loaded titanate zirconium phosphate composite nanomaterial.

Embodiment 2

[0025] Add 2 grams of sodium titanate powder into 100 milliliters of deionized water, and stir evenly. 5 ml of phosphoric acid was added, and the pH of the solution was adjusted to 3 with ammonia. Then add 0.04 g of silver nitrate and stir to dissolve. It was then stirred in the dark for 24 hours. At the same time, 1.0 g of zirconium nitrate pentahydrate was added to 30 ml of deionized water, and stirred to dissolve. After the stirring in the dark, the zirconium nitrate solution was added to the former solution, and the stirring was continued in the dark for 6 hours. After stirring, the precipitate was washed with deionized water until the pH of the washing solution was neutral, and then dried. Afterwards, it was fired at 600 degrees for 3 hours to obtain the target silver-loaded titanate zirconium phosphate composite nanomaterial.

Embodiment 3

[0028] Add 5 grams of potassium titanate powder into 200 milliliters of deionized water, and stir evenly. 10 ml of phosphoric acid was added, and the pH of the solution was adjusted to 2 with aqueous ammonia. Afterwards, 0.2 g of silver nitrate was added under light-shielding conditions, and stirred to dissolve. It was then stirred for 36 hours in the dark. At the same time, 1.5 grams of zirconium carbonate was added to 30 milliliters of deionized water, and stirred to dissolve. After the stirring in the dark, the zirconium carbonate solution was added to the former solution, and the stirring was continued in the dark for 5 hours. After stirring, the precipitate was washed with deionized water until the pH of the washing solution was neutral, and then dried. Afterwards, it was fired at 900 degrees for 2 hours to obtain the target silver-loaded titanate zirconium phosphate composite nanomaterial.

Abstract

The invention discloses a method for preparing a silver-loaded titanate-zirconium phosphate composite nanometer material. The method comprises the steps of: firstly, adding titanate into deionized water to be dispersed, adding phosphoric acid; regulating pH using ammonia water, adding silver nitrate after uniform dispersion; stirring the resulting solution under a light-proof condition for 6-24 hours; adding an aqueous solution of zirconium salt, and further stirring the resulting solution under the light-proof condition for 2-8 hours; washing and drying a sediment product after the stirring operation is ended; and roasting the sediment product at the temperature of 500-1200 DEG C to obtain the target product silver-loaded titanate-zirconium phosphate composite nanometer material. The preparation method is simple and convenient in process and flow, wide in parameter adjustable range, strong in repeatability, low in cost, conductive to large-scale production, and has good business prospect.

Description

technical field [0001] The invention relates to a preparation method of a titanate zirconium phosphate composite nano material, in particular to a preparation method of a silver-loaded titanate zirconium phosphate composite nano material, belonging to the technical field of inorganic nano material preparation. Background technique [0002] Layered titanate is a wide bandgap semiconductor material. Because of its unique layered structure, its specific surface area is much larger than that of titanium dioxide nanomaterials. It has extremely high ion exchange, transport and adsorption capabilities, and can maintain good ion exchange. stability. Therefore, it can be used in lithium-ion batteries, catalytic oxidation, ion adsorption, antibacterial coatings, ammeters, heat insulation materials, etc., and thus has received increasing attention. [0003] Nano-silver can kill as many as 650 kinds of Gram-positive bacteria, Gram-negative bacteria, fungi, molds, etc. in contact with i...
