英文摘要A Zr-MOF with an acidic ionic liquid linker ([bpyH][CF3SO3]) were externally hydrophobized with polydimethylsiloxane (PDMS) via a vapor deposition method (denoted as PDMS@UiO-67-CF3SO3). The morphology of UiO-67-CF3SO3 was well maintained after PDMS coating, and PDMS had little effect on the chemical properties of UiO-67-CF3SO3, while the hydrophobicity of the surface of UiO-67-CF3SO3 was improved greatly as demonstrated by water contact angle measurement. The derived hydrophobized PDMS@UiO-67-CF3SO3 exhibited excellent catalytic performance in the esterification of acetic acid and isooctyl alcohol, it only needed 4 h to reach the reaction equilibrium, while for UiO-67-CF3SO3, it was 18 h. The decrease in reaction time was mainly attributed to the accelerated the removal of water and isooctyl acetate, resulting the increase rate in the forward reaction. In addition, in the other esterification of acids and alcohols, PDMS@UiO-67-CF3SO3 also showed good catalytic performance.
