Synthesis of Cu-BTC metal-organic framework for CO2 capture via solvent-free method: Effect of metal precursor and molar ratio

The Cu-BTC (Copper-1,3,5-benzene tricarboxylate) is one of the representative metal organic frameworks (MOFs) that has shown outstanding performance for carbon dioxide (CO2) adsorption. However, its conventional synthesis duration is relatively long, and the process requires the addition of bulk amo...
