摘 要：Post synthetic modification of a hydrophilic metal-organic framework(MOF),HKUST-1,with stearic acid(SA)was carried out to enhance the stability of HKUST-1 in aqueous solution to be used as a support for formate dehydrogenase(FDH)used for CO_(2)conversion to *** modification improved the hydrophobicity without affecting the morphology and crystal structure of *** of FDH on the modified MOF(SA@HKUST-1)was compared to that of the native HKUST-1 and *** adsorption kinetics on all MOFs was found to follow pseudo-second order kinetics and the isotherm was best described by Freundlich *** high stability of SA@HKUST-1 and enhanced hydrophobic interaction between support and CO_(2)resulted in high catalytic efficiency and stability of FDH@SA@*** immobilized enzyme retained 95.1%of its initial activity after 4 cycles of repeated *** was also shown that FDH@SA@HKUST-1 retained morphology and crystal structure after repeated *** of the present work provide novel insight into the influence of hydrophobic MOFs on the activity and stability of immobilized *** findings are expected to assist in developing highly active and stable biocatalysts for CO_(2)hydrogenation at commercial level.
