| There are three parts in this paper. The first part is focused on the design and preparation ofa novel inorganic–organic hybrid compound based on the exploration and research ofpolyoxometalates. In the second part, we explored a simple, green synthesis strategy forsynthesizing an integrate thin Cu3(BTC)2porous membrane. And in the third part,multi-functionality membrane based on the polyoxometalates and meal-organic framework, withthe formula of [Cu3(BTC)2(H2O)3]4[{(CH3)4N}2HPW12O40](denoted as G@Cu3(BTC)2forshort) is obtained on the copper slice. In the structure of G@Cu3(BTC)2, Keggin-typepolyoxometalates are selectively embedded in the vacant pores of Cu3(BTC)2, which can narrowthe channels of Cu3(BTC)2film. And initially we explore the catalytic effect as a catalyst forhydrogen peroxide bleaching methyl orange experiments.Polyoxometalates (POMs) are inorganic and organic metal oxide clusters with nanometerdimensions. Compared with inorganic acids are more acidic and excellent in oxidationresistance, and also has a composition, diverse, multiple diverse nature, and thus in the field ofthe catalytic, optical, magnetic, electrical, drugs etc. have important and widely used. So it hasbeen a hot topic of concern. A novel inorganic–organic hybrid compound [Co(phen)3]2[V10O28]has been hydrothermally synthesized and characterized by elemental analysis, IR spectrum andsingle-crystal X-ray diffraction. Crystal data: monoclinic, space group: C2/c. a=2.4505nm, b=1.5484nm, c=2.2595nm, α=90°, β=107.857°, γ=90°, V=8.160nm3, Z=4, R1=0.0702, ωR2=0.1421.MOFs are a new type of organic and inorganic porous crystalline material, and because ofthe diversity channels can be designed or modified, and thus have a wide range of applicationsin the separation, catalysis, biochemical, pharmaceutical and gas storage.Studies have been verygood development. This paper selection is focuse on one of the most extensive studies of porousmetal-organic framework materials–HKUST-1, for the first time at room temperature withdistilled water and ethanol chosen as solvent, select trimesic acid as reactants, the crystalHKUST-1metal organic framework on the copper net or the copper slice. Copper slice orcopper net is as a source of the reaction, not only provides a uniform reaction of nucleation sites,but a large concentration so that the reaction time is relatively fast, the resulting film iscontinuous and complete, and the thickness of the tight particle is about20micron. And the strategy may be possible to prepare large-scale uniform and continuous thin HKUST-1member.Multi-functionality porous crystalline membrane based on the polyoxometalates andmeal-organic framework, is acid modification of the Cu3(BTC)2membrane pores as to reduceregular pore size. At first, via solvothermal synthesis, the surface of copper was modified bygrowing a thin layer of Cu3(BTC)2. Then, via hydrothermal synthesis, an integrant film, with theformula of G@Cu3(BTC)2, was fabricated at the modified surface of copper. In G@Cu3(BTC)2film, PW12O403-and (CH3)4N+were embedded as guests in certain key free pores of Cu3(BTC)2framework. Thus, compared with pure Cu3(BTC)2film, G@Cu3(BTC)2film has narrowerchannels for molecular transport, which may enable it to exhibit higher permeation selectivity insmall-molecule separation field. In this work, we concluded that solvothermal and hydrothermalsynthesis have huge potential for tailoring the performances of MOF films toward desiredapplications. By controlling the amount of experimental material, pH, the time, and temperature,with the second crystal growth method, we have succeeded to obtain the desired film on themetal copper, and its catalytic characterization experiments experiments show that the filmsprepared shows excellent results. |
