【摘要】：近十几年以来,多孔有机骨架(porous organic framework,POF)材料由于其较轻的骨架,可调控的孔道范围以及较高的比表面积引起了世界各地科学家的广泛研究兴趣。多孔有机骨架材料在众多研究领域里,比如气体存储、气体分离、异相催化、光电等方面都有着广泛应用。多孔芳香骨架(porous aromatic framework,PAF)材料作为多孔有机材料中的一个重要成员,在过去的十几年中得到广泛研究,发展迅速。本论文旨在合成新型的骨架中含氮元素的多孔芳香骨架材料,并探究其气体吸附性质和其掺杂金属的异相催化能力。本论文首先选用了含有氰基基团的二维单体为结构单元,在氯化锌的催化下,借助高温,通过离子热的反应合成出了新型的多孔芳香骨架材料(PAF-72)。PAF-72具有良好的热稳定和化学稳定性,其BET比表面积为582 m2 g-1。在室温下,对温室气体如二氧化碳、甲烷有良好的吸附能力,并且对于液体蒸汽(例如苯、甲苯、乙醇蒸汽等)也有很好的吸附作用。其次,本论文又以PAF-72为载体,合成出了金属钌负载的催化剂Ru/PAF-72,其可以在室温中催化硼烷氨络合物的水解产氢,具有良好的催化活性和循环稳定性。与纯炭黑负载金属钌材料的催化实验结果对比,体现出了含氮的PAF-72材料作为载体的优势。多孔芳香骨架材料的制备以及作为金属担载的载体进行催化反应,丰富了多孔有机材料的应用,并且展现出了一定的气体吸附能力和良好的催化效果。这也为其广泛的应用于其它的催化反应类型提供了极大的潜力和无限可能。
[Abstract]:In the past decade, porous organic organic frames have been used as a material because of their lighter skeletons. Adjustable pore ranges and high specific surface areas have attracted a wide range of research interests among scientists around the world. Porous organic skeleton materials have been studied in many fields, such as gas storage, gas separation, heterogeneous catalysis, As an important member of porous organic materials, porous aromatic aromatic frames have been widely studied in the past decade. The purpose of this thesis is to synthesize new porous aromatic skeleton materials containing nitrogen in skeleton. The gas adsorption properties and heterogeneous catalytic ability of doped metals were investigated. Firstly, the two-dimensional monomers containing cyanide groups were selected as structural units, with the help of high temperature, under the catalysis of zinc chloride. A new porous aromatic skeleton material, PAF-72N 路PAF-72, was synthesized by ion-thermal reaction. Its BET specific surface area was 582m2 g ~ (-1). At room temperature, a new porous aromatic skeleton material, PAF-72N, PAF-72, had good adsorption capacity for greenhouse gases such as carbon dioxide and methane, and its specific surface area was 582m2 / g ~ (-1). And the liquid vapor (such as benzene, toluene, ethanol vapor, etc.) also has a good adsorption. Secondly, this paper takes PAF-72 as the carrier, Rur / PAF-72 catalyst supported on metal ruthenium was synthesized, which can catalyze the hydrolysis of borane ammonia complex to produce hydrogen at room temperature, and has good catalytic activity and cyclic stability. The results are compared with those of pure carbon black supported ruthenium material. The advantages of nitrogen-containing PAF-72 as carrier are demonstrated. The preparation of porous aromatic skeleton materials and the catalytic reaction as metal supported carriers enrich the application of porous organic materials. It also shows certain gas adsorption ability and good catalytic effect, which provides great potential and infinite possibility for its wide application in other catalytic reactions.
