分别通过用官能化配体对有机连接基进行后官能化或预改性来制备磺氧基或磺酸官能化的MIL-101催化剂，后者是所谓的一锅合成法。采用XRD、N2吸附、酸碱滴定、FT-IR等手段对催化剂进行了系统的表征，并将其应用于一元羧酸与一元醇的液相酯化反应。结果表明，磺酸官能化的MIL-101通过一锅法合成的S-MIL-101催化剂在酯化反应中的催化活性高于相应的磺酸功能化的MIL-101（S/MIL-101）通过后官能化方法制备，这是因为S-MIL 101具有较高的酸负载量和高的官能化酸位点利用效率。此外，S-MIL-101是稳定的浸出，作为一个真正的多相催化剂，可以很容易地通过过滤回收，并可以重复使用五次连续没有任何损失的催化活性。
The sulfoxy or sulfonic acid-functionalized MIL-101 catalyst was prepared by either post-functionalization or pre-modification of the organic linkers with the functionalized ligands, respectively, the latter is the so-called one-pot synthesis method. These catalysts were systemically characterized by XRD, N2 adsorption, acid–base titration, and FT-IR techniques and applied in the liquid-phase esterification of monocarboxylic acids with monohydric alcohols. The results show that the sulfonic acid-functionalized MIL-101 (S-MIL-101) prepared by the one-pot synthesis method possesses a higher catalytic activity in the esterification than its counterpart the sulfoxy acid-functionalized MIL-101 (S/MIL-101) prepared by the post-functionalized method, due to the fact that S-MIL101 has a higher acid loading and a high utilization efficiency of the functionalized acid sites. Moreover, S-MIL-101 is stable to leaching, behaves as a true heterogeneous catalyst, can be easily recovered by filtration, and can be reused five times in succession without any loss of its catalytic activity.
