Embodiment 1

[0033] Soak the AAO template in deionized water and sonicate for 10 minutes. After the ultrasonic treatment, the AAO template was placed in an aqueous gelatin solution with a concentration of 0.8% by mass, and soaked for 30 minutes, wherein the temperature of the aqueous gelatin solution was 70°C. Take the AAO template out of the gelatin aqueous solution, rinse both surfaces with 95°C deionized water to remove the gelatin on the template surface, immediately place it in an aqueous solution of alum with a concentration of 1% by mass, soak for 5 minutes, and the temperature of the aqueous alum solution is 0 ℃. Soak the above-treated AAO template in a concentration of 0.5mol.L -1 In the potassium iodide solution, the soaking time is 10 minutes. After removing the AAO template from the potassium iodide solution, the surface was quickly rinsed with deionized water, and then fixed on a surface such as figure 1 In the reaction apparatus shown.

Abstract

The present invention belongs to the field of nanometer mesoporous material technology, and is especially chemical deposition process of preparing composite nanometer mesoporous silver halide / alumina material with porous alumina template as mesoporous solid. The preparation process includes the first ultrasonic treatment, and soaking in gelatin solution, hardening agent solution and halogen anion salt solution successively of AAO template; the subsequent reaction of the treated template in a connector in the shown structure and with silver ion solution and halogen and silver ion solution filled separately on two sides of the template; and final soaking the reaction product in water solution of glycerin to eliminate gelatin and in deionized water to eliminate impurity ions. The present invention has the pores in AAO template filled with nanometer AgX lines in the length comparative with the thickness of AAO template.

Description

technical field [0001] The invention belongs to the field of nano mesoporous composite materials, in particular to a method for preparing a silver halide / alumina nano mesoporous composite material using a chemical deposition method and a porous alumina template as a mesoporous solid. Background technique [0002] Nano-mesoporous composite material is an attractive research object in the field of nanomaterials science in recent years. It is a composite solid formed by introducing nano-sized ultrafine particles into the pores or cages of mesoporous solids by physical or chemical methods. An assembled system or association of both particles and mesoporous solids. Therefore, nano-mesoporous composites possess some unique properties of nanoparticles and mesoporous solids. [0003] At present, a variety of mesoporous solids have been applied to the preparation of nano-mesoporous composites, and anodic aluminum oxide (Anodic Aluminum Oxide, AAO) template is one of them. AAO templ...
