[Abstract]:Porous materials have attracted much attention due to their large specific surface area, uniform pore size and controllable skeleton composition. It is widely used in catalysis, adsorption, separation, gas storage and other fields. This thesis is devoted to the synthesis of amino functionalized porous polymer materials, functionalized multiporous zeolite catalysts and magnetic separable functional porous carbon materials. The applications of the functionalized porous materials in the synthesis of fine chemicals and the adsorption of organic dyes in water were systematically studied. In the first chapter, the types and progress of porous materials are briefly summarized. Combined with the problems that need to be solved in the study of porous materials, the research goal and significance of this paper are put forward. In the second chapter, porous polymers with large specific surface area were prepared by solvothermal method without template, and then nano-porous solid bases with excellent catalytic performance were obtained by nitrification and reduction. Then the alkali-catalyzed activity of the material was studied, and its rich porous structure, unique superhydrophobic properties and anti-toxic effect against carbon dioxide were characterized. The results show that the material has rich nano-pore structure, many catalytic active sites, superhydrophobicity, insensitivity to carbon dioxide, and so on, which can be used in green and sustainable alkali-catalyzed processes. The catalytic preparation of various fine chemicals with high added value has important potential application value. In chapter 3, mesoporous ZSM-5 single crystals with b-axis growth, supported PD and transition metal oxides have been prepared. Then the catalytic oxidation of the material was investigated, and its unique pore structure and zeolite framework were characterized. The results show that ZSM-OM-PdOx-MOX has abundant nano-pores and highly crystallized skeleton structure, PD and active species of transition metals are uniformly dispersed in the ZSM-5-OM pore channel, which shows unique interaction and is beneficial to the activation of oxygen molecules. Furthermore, the ability of selective catalytic oxidation was enhanced. In chapter 4, regular mesoporous carbon materials with partially graphitized framework and controllable surface wettability were prepared. The introduction of iron species in the synthesis process gives the materials novel magnetic separation characteristics PR-Fe-P123-800 and PR-Ni-P123-800. Then the selective adsorption of pollutants in water was studied, and its unique graphitization structure, magnetic separation and regular mesoporous structure were characterized. The results show that the special magnetic classification and adsorption properties of PR-Fe-P123-800 and PR-Ni-P123-800 have important application value for their application in the removal of various organic pollutants in water.
