【Abstract】 Nano - sized pores inside the mesoporous materials can be used to support the nanoparticles to form functional materials. The basic features and preparing technologies of mesoporous materials such hydrothermal method, sol - gel technique and microwave method were introduced. The authors have developed a novel method for preparing micro/meso-porous materials from layer silicates by mechanochemical activation and subsequent leaching. The techniques and functional features of mesoporous materials assembling elements, sulphides, oxides and composite particles are primarily described . The mechanism of nano - structured assembly is analysized. Application of fractal in mesoporous characterization are pointed out. Development prospect of the field is also expected.更多还原
