Defective NH2-UiO-66(Zr)effectively converting CO2 into cyclic carbonate under ambient pressure,solvent-free and co-catalyst-free conditions
文献摘要：
In this study,a series of metal-organic frameworks(MOFs)NH2-UiO-66-xHAc catalysts were synthesized by solvothermal method using acetic acid(HAc)as a modulator,and were applied to the cycloaddition of CO2 and epichlorohydrin(EPIC)under ambient pressure.Influences of the modulation by HAc on mor-phologies and structures of the MOFs are demonstrated via PXRD,FESEM,FTIR,N2 adsorption-desorp-tion,XPS and 1H NMR characterizations.The results show that the MOFs containing mesoporous pores can be prepared by adjusting the concentration of HAc.By optimizing the amount of HAc added,the specific surface area of NH2-UiO-66-8HAc is as high as 879.17 m2.g-1,which is 28.3％higher than that of the original MOFs.And the evaluation of catalytic performance showed that HAc modulation enhanced the activity of NH2-UiO-66-xHAc under mild conditions.The exposure of Lewis acid sites,increased speci-fic surface area and porosity via the modulation of HAc defective ligand can be supposed the key factors to determine the enhanced catalytic activities.In addition,considering the influence of gas concentration on the reaction,the concept of TOP(Turnover of Pressure,defined as the mass of conversions of a unit mass catalyst under unit pressure and unit time)was first proposed in this article.
