Abstract
A method for making the mesoporous material includes the following steps: dissolving a nanocrystal powder in an organic solvent, and achieving a solution A with concentration of 1-30 mg/ml; dissolving a surfactant in water, and achieving a solution B with an approximate concentration of 0.002-0.05 mol/ml; mixing the solution A and the solution B in a volume ratio of 1:(5-30), and achieving a mixture; stirring and emulsifying the mixture, until an emulsion C is achieved; removing the organic solvent from the emulsion C, and achieving a deposit; washing the deposit with deionized water, and achieving a colloid; and drying and calcining the colloid, and eventually achieving a mesoporous material. The mesoporous material has a large specific surface area, a high porosity, and a narrow diameter distribution.
