【摘要】：多孔材料在催化、發(fā)光、磁學(xué)性質(zhì)、傳感、分子識(shí)別、氣體的存儲(chǔ)、選擇性吸附、分離等不同領(lǐng)域具有潛在的應(yīng)用前景。在過去的20年里,金屬 有機(jī)骨架(MOFs)材料因具有孔道尺寸可控、表面易功能化、高的比表面積、穩(wěn)定的骨架結(jié)構(gòu)等特點(diǎn)而引起人們的廣泛關(guān)注。隨著經(jīng)濟(jì)社會(huì)發(fā)展和人們對(duì)環(huán)境污染治理問題的重視,尋找無毒無害的吸附材料越來越成為科研工作者一個(gè)研究焦點(diǎn)。利用MOFs的多孔性、比表面積大、骨架穩(wěn)定等特點(diǎn)處理染料廢水也自然成為一個(gè)重要的研究課題。本論文選用合成的具有偶氮、羧酸的配體L1(吡啶-4-甲基-3-((4-(吡啶-4-甲氧基)苯基)偶氮)苯甲酸酯)和L2(吡啶-4-甲基-4-((4-(吡啶-4-甲氧基)苯基)偶氮)苯甲酸酯),以Zn(Ⅱ)為金屬中心離子,采用溶劑熱的合成方法,制備出了九種新的配合物,分別為[Zn2L12(5-OH-BDC)2(H2O)1.5]n(1)(5-OH-H2BDC=5-羥基間苯二甲酸)、[ZnL1(5-CH3-BDC)]n(2)(5-CH3-H2BDC=5-甲基間苯二甲酸)、[ZnL1(5-NO2-BDC)]n(3)、[ZnL1(5-NO2-BDC)(H2O)]n(4)、[ZnL1(5-NO2-BDC)]n(5)(5-NO2-H2BDC=5-硝基間苯二甲酸)、[ZnL1(BDC)]n(6)(H2BDC=間苯二甲酸)、[ZnL2(5-CH3-BDC)]n(7)、[ZnL2(5-CH3-BDC)]n(8)、[ZnL2(5-BDC)]n(9)等九種新的金屬 有機(jī)骨架(MOFs)配合物。通過單晶衍射、X-射線粉末衍射(XRD)、紅外(IR)、熱重(TG)等手段對(duì)其進(jìn)行表征。著重研究配合物[Zn2L12(5-OH-BDC)2(H2O)1.5]n(1)對(duì)剛果紅、酸性黑10B、直接紅80、甲基橙、橙黃Ⅱ等陰離子染料選擇性吸附。
[Abstract]:Porous materials have potential applications in different fields, such as catalysis, luminescence, magnetic properties, sensing, molecular recognition, gas storage, selective adsorption, separation and so on. Due to its controllable pore size, easy surface functionalization and high specific surface area, the metal / organic skeleton / MOFs material has high specific surface area. With the development of economy and society, people pay more attention to the problem of environmental pollution treatment. The search for non-toxic and harmless adsorption materials has become a research focus of researchers. Using the porous properties of MOFs, the specific surface area is large. The treatment of dye wastewater with skeleton stability has naturally become an important research topic. In this paper, the synthetic azo has been selected.
