The anionic rhodium complex -[Rh(CO)I], active in the Monsanto process for acetic acid production, has been heterogenised Coulombic interactions in the pores of a UiO-66-type metal-organic framework (MOF). The MOF-supported catalyst is active for the carbonylation of methanol and is recyclable, retaining its framework crystallinity following catalysis. Intermediates in the catalytic cycle observed by IR spectroscopy confirm the same mechanism as the established homogeneous process.
阴离子铑配合物-[Rh(CO)I]，在孟山都醋酸生产工艺中具有活性，已通过库仑相互作用在UiO-66型金属有机框架（MOF）的孔中实现了多相化。该MOF负载的催化剂对甲醇羰基化反应具有活性且可循环使用，催化后仍保持其框架结晶度。通过红外光谱观察到的催化循环中间体证实了与已确立的均相过程相同的机理。
