Preparation method and application of Zn-MOFs/Ti3C2Tx composite material for H2/CO2 separation

The invention discloses a preparation method and application of a Zn-MOFs/Ti3C2Tx composite material for H2/CO2 separation, and belongs to the technical field of material preparation. The method comprises the following steps: dispersing accordion-shaped Ti3C2Tx in a water/methanol solution, adding zinc salt and lauryl sodium sulfate (SDS), slowly pumping into the water/methanol solution containing methylimidazole and dimethylimidazole in the stirring process, and reacting to obtain Zn-MOFs/Ti3C2Tx. The obtained composite material is subjected to vacuum filtration to obtain a membrane material which is used for separating H2/CO2. The preparation method is simple, due to the introduction of lauryl sodium sulfate, a Ti3C2Tx lamella can be stripped in situ, and more adsorption active sites are provided; due to introduction of Zn-MOFs, more adsorption pore channels except for stacked pores can be provided, and in addition, an imidazolyl ligand belongs to an alkaline ligand, so that acidic CO2 can be more effective
