The Study Of Inorganic Porous Materials For Gas And Vapor Adsorption Properties

In recent decades, synthesis of new materials is materials science rapid development of the most obvious manifestation of porous zeolite materials, the unique structure and nature of it in various fields can be quickly be developed and utilized. Is widely used in industrial and agricultural production, environmental protection, national defense and many other high-tech fields, has become an important and indispensable new materials. In zeolite materials widely used in the new performance and new structures continue to demand more for a new type of zeolite materials research and development, at the same time, a novel structure of zeolite materials synthesis, characterization, physical and chemical properties and application by people's attention. This particular porous material and the nitrogen adsorption and vapor adsorption were more in-depth research.First of all, we have the conventional MCM-41, SBA-15, ZSM-5 zeolite materials and Y-type zeolite materials to ethanol, acetone, benzene, cyclohexane and other organic vapor adsorption capacity of a detailed analysis, SBA - 15 and MCM-41 with two other microporous samples, compared with significantly greater total pore volume, so when close to the solvent saturation vapor pressure, the adsorbate molecules in the mesoporous channels occurred within a multi-layer adsorption, almost filled all of the channels, Er Shi mesoporous materials on the solvent molecules have a greater adsorption capacity, so that the organic pollutants removal has potential applications.Because the micro - mesoporous molecular sieves materials to avoid the microporous material coke serious shortcomings, and its diameter than the microporous material of large, diffuse and better. Based on these advantages, we are on a new type of micro - mesoporous molecular sieves materials adsorption properties of the study, we not only according to BET model has been sample accurate surface area, but also through the absorption curve, mesoporous pore size distribution test The results of the samples specific surface area and mesoporous pore size distribution increases to the reasons of the right to judge.In summary, the gas adsorption and vapor adsorption applied to zeolites in the field, for our in-depth study of Mesoporous channel information has a very big help, will be of zeolite materials, a powerful tool.
