A calcium-based microporous metal-organic framework for efficient adsorption separation of light hydrocarbons

Ideal metal-organic frameworks (MOFs) are those have not only significant adsorption separation performances but also excellent vapor and/or thermal stability. In this work, a calcium-based metal-organic framework with high vapor-stability and thermostability, Ca(squarate), was prepared using readily available precursor (CaCO3) and squaric acid as starting materials by hydrothermal method. Characterization techniques including PXRD, TGA and BET...
