Synthesis of ZIF-8@GO compositesand its adsorption properties to  CO2

Abstract

Abstract: The greenhouse effect caused by CO₂ emissions from fossil fuel combustion is becoming more and more serious, it is urgent to develop adsorbents with CO₂ adsorption properties. As new adsorbents, metal-organic frame materials (MOFs) and graphene oxide (GO) have the problem of low CO₂ adsorption performance. ZIF-8@GO was prepared by solvothermal method, and the microstructure and adsorption properties of ZIF-8@GO to CO₂ were studied by XRD, SEM and BET. The results showed that ZIF-8@GO maintains the crystal structure of ZIF-8, and GO mainly plays a role in size regulation and structure orientation of ZIF-8. The gas adsorption separation test showed that ZIF-8@GO is the same as ZIF-8, which is dominated by micropores. Notably, when the GO participation ratio is 8%, the BET and Langmuir specific surface areas of ZIF-8@GO(8%) materials are 1 037.18, 1 115.90 m²/g, respectively, and theadsorption capacity to CO₂ is 34.347 cm³/g. Compared with the parent ZIF-8 material, the CO₂adsorption capacity is increased by 32.3%.
