Abstract

The invention relates to preparation and application of a metal organic framework material Ni-based MOF-74, and aims to solve the problems that an existing CO2 sensor is small in detection range, tedious in preparation process and complex in test. The preparation method comprises the following steps: 1, pretreating ITO glass; 2, preparing a Ni (NO3) 2.6 H2O and 2, 5-dihydroxy terephthalic acid solution by taking DMF (Dimethyl Formamide) as a solvent; and 3, preparing a mixed solution, putting the mixed solution into ITO glass, and reacting in a reaction kettle to obtain the Ni-based MOF-74. The method is applied to preparation of a CO2 gas detector so as to carry out full-concentration detection of CO2. The microporous structure and the high specific surface area of the Ni-based MOF-74 provide guarantee for CO2 adsorption. The prepared CO2 gas detector has the advantage of wide CO2 detection range, can be used for full-concentration detection of CO2, and is simple in detection process, easy to operate, low in cost, simple in process and suitable for industrial production. The Ni-based MOF-74 prepared by the preparation method disclosed by the invention is applied to a CO2 gas detector.

Description

technical field

[0001] The invention specifically relates to the preparation and application of a metal-organic framework material Ni-based MOF-74. Background technique

[0002] With the rapid development of urbanization and industrialization, the consumption of fossil fuels is increasing year by year, and the emission of greenhouse gases is also increasing year by year, resulting in the increasing greenhouse effect. As global warming worsens, the frequency of extreme weather around the world increases, and biodiversity is seriously threatened. During global warming, carbon dioxide (CO 2 ) plays the largest role in many greenhouse gases. In order to actively respond to the environmental protection policies of "carbon peaking" and "carbon neutrality", online real-time monitoring of CO 2 Emissions are important. CO 2 Detection technology has been in a stage of slow development, and the existing sensors mainly have shortcomings such as cumbersome preparation process, small ...
