Abstract

The invention relates to the preparation of silver phosphate two-dimensional ordered nano-network film and its method at the gas-liquid interface. Polystyrene balls are used to form an ordered single-layer self-assembled film at the gas-liquid interface, and the liquid surface of the silver nitrate aqueous solution is transferred. slow release of reactive gas, silver nanocrystals are coated on the surface of polystyrene spherical template, which has a two-dimensional ordered nano-network structure in a large area, and then transferred to hydrogen peroxide reaction solution, and phosphoric acid is obtained through in-situ displacement reaction Silver-polystyrene two-dimensional ordered structure, and finally soaked in toluene solution to remove the polystyrene template. The thickness of the film in the silver phosphate two-dimensional ordered nanonet film prepared by the invention is uniform, the degree of crystallization is good, the long-range order is good, and it can be prepared in a large area. The catalytic performance of its photocatalytic degradation of organic dyes is better than that under the same conditions. Silver phosphate single crystal material, which is used as a supercapacitor electrode, has good cycle performance and has good applications in the fields of photocatalysis and supercapacitors.

Description

technical field [0001] The invention relates to a method for preparing a structure-controllable inorganic semiconductor material film, in particular to a method for preparing a silver phosphate two-dimensional ordered nano-network film at a gas-liquid interface. Background technique [0002] Silver phosphate nano-semiconductor materials have excellent photoelectric properties, and have been well applied in the fields of photolysis of water to produce oxygen, nano-antibacterial, photodegradation of organic dyes, and supercapacitors. "Facet Effect of Single-CrystallineAg 3 PO 4 Sub-microcrystals on Photocatalytic Properties” [Bi, Y.P.; Ouyang, S.X.; Umezawa, N.J.Am.Chem.Soc, 2011, 133, 6490–6492]. At present, among the reported silver phosphate-based nanomaterials, it can be found that due to Silver phosphate has the characteristics of rapid nucleation in the solution phase, and its morphology control mainly focuses on the composite structure of zero-dimensional and one-dimen...
