AI Technical Summary

Problems solved by technology

And the stacking of flaky packing is too dense, which is not conducive to the penetration of gas, which will greatly affect the adsorption of gas
There are organic guests in the unactivated MOF structure, which will occupy the pores, reduce the adsorption sites of gases, and reduce the amount of gas adsorption

Abstract

The invention relates to the technical field of hybrid materials, in particular to a preparation method of a microporous metal organic framework Cu(Qc)2. According to the preparation method of the microporous metal organic framework Cu(Qc)2, a simple, convenient and efficient method for synthesizing the MOF material Cu(Qc)2 at the room temperature is provided, Cu(Qc)2 is successfully synthesized at the room temperature within 1-12 h with (Zn, Cu) hydroxyl double salt as an intermediate, and the obtained Cu(Qc)2 has good carbon dioxide adsorption capacity.

Description

technical field [0001] The invention relates to the technical field of hybrid materials, especially a microporous metal-organic framework Cu(Qc) 2 method of preparation. Background technique [0002] Carbon dioxide is ubiquitous in many chemical and energy production processes or exists as an impurity in raw materials. Its existence will seriously affect the purity and utilization of products or raw materials. Therefore, there is an important practical demand for separating carbon dioxide from industrial gases. For example, the main component of natural gas is methane, but it contains about 10% carbon dioxide (CO 2 ), carbon dioxide is usually pre-removed in order to meet transportation standards, and the requirement for pipeline natural gas is CO 2 <=3%, LNG is CO 2 <50ppm. [0003] In recent years, metal-organic framework materials (Metal-Organic Framework, referred to as MOF) have been attracting attention for their rich topology and applications in gas storage ...
