preparation example Construction

[0024] The preparation method of following Zr-MOF material: get 1.165g zirconium chloride (ZrCl 4 ), 0.831g terephthalic acid (C 8 h 6 o 4 ), 30mL DMF solution and 0.8ml concentrated HCl solution were fully stirred to dissipate heat, then moved to a homogeneous reaction kettle, and then put the reaction kettle into a constant temperature drying oven at 120°C for 24 hours and then naturally cooled to room temperature. Filter, wash with DMF, wash with methanol, dry in a drying oven at 100°C for 6 hours, wash with acetone, and dry in a drying oven for 6 hours to obtain the Zr ion metal organic framework material.

[0025] The following is the preparation method of Ru / Zr-MOF material: the concentration of 2.15mL is 0.0266g. ml -1 RuCl 3 The solution was added to 1 g of the Zr-MOF material, stirred, and left to stand at room temperature for 12 hours to obtain a 2% Ru / Zr-MOF material precursor. The 2% Ru / Zr-MOF material precursor was moved to an atmospheric pressure-cooled pla...

Embodiment 1

[0027] Co-activation of CO by a metal-organic framework material loaded with noble metal and plasma 2The method for preparing C1 organic product, described method is that 0.3g above-mentioned 2%Ru / Zr-MOF material is joined in the coil type dielectric barrier plasma discharge reactor, feeds reaction gas (VH 2 :VCO 2 =4:1), adjust the peak-to-peak value of discharge voltage to 19.2kV, conduct CO 2 Hydrogenation conversion is used to prepare C1 organic products, and the reaction products are detected online by gas chromatography.

Embodiment 2

[0029] Co-activation of CO by a metal-organic framework material loaded with noble metal and plasma 2 The difference between the method for preparing the C1 organic product and Example 1 is that 0.2 g of Zr-MOF is used to replace 2% Ru / Zr-MOF in Example 1.

Abstract

The invention relates to a method for preparing a C1 organic product by supporting precious metals on a metal-organic framework (MOF) material and performing plasma coactivation on CO2 and belongs tothe field of CO2 conversion and application. The method comprises the following steps: supporting precious metals on the organic framework material by adopting an impregnation method, further adding into a cold plasma discharge reactor, introducing working gases, taking a barometric pressure as the gas pressure, regulating the discharge voltage peak value to 15-40kV, and reducing the precious metals; further adding the reduced M / MOF into an atmospheric dielectric barrier discharge plasma reactor, introducing mixed gases of CO2 and H2, and preparing the C1 organic product through CO2 conversion. The method disclosed by the invention has the beneficial effects that the CO2 conversion rate and C1 product selectivity are improved, and the framework structure of the material can be effectivelymaintained.

Description

technical field [0001] The invention relates to a co-activation of CO with a loaded metal-organic framework material and atmospheric pressure-cooled plasma 2 method, belonging to CO 2 Transformation and application fields. Background technique [0002] Metal-organic frameworks (MOFs) are a new type of crystalline solid-state materials, generally a three-dimensional network structure formed by covalently connecting central metal ions and organic multidentate ligands. Metal-organic frameworks are widely used in gas storage, gas separation, sensors, and drug carriers due to their designable structural properties, high specific surface area, and uniform pore size. Compared with traditional adsorption materials, MOFs show great potential application prospects. In recent years, there have been many reports on the application of emerging porous materials MOFs as catalyst supports. Such as Zhang et al [Zhang S Q, Li L, Zhao S G, Sun ZH, Luo J H. Construction of interpenetrated r...
