本文主要研究内容
作者(2019)在《Methane Storage and Synthesis of HKUST-1 Prepared with Different Solvent》一文中研究指出:The metal-organic framework HKUST-1 was prepared by different solvents.Several analytical tools such as scanning electron microscope(SEM),X-ray diffraction(XRD),N2 adsorption-desorption have been used to characterize the as-synthesized samples.Meanwhile,the solubility of organic ligands in solvents and the CH, adsorption capacity of samples were also detected.The results showed that HKUST-1 prepared with N,N-dimethylformamide(DMF)used as solvent exhibited excellent CH4 adsorption performance.Further studies have shown that the improved CH4 adsorption properties could be attributed to higher solubility of the ligand 1,3,5-benzenetricarboxylic acid in DMF and larger specific surface areas.This work can provide a novel sight for preparing highly efficient CH4 adsorbent materials by improving the solubility of ligand.
