The purpose of this perspective article is to compare the catalytic activity of well isolated tetravalent metal sites in microporous zeolites with those present in the oxo-metallic nodes of metal–organic frameworks. Several acid (or acid–base) catalyzed organic transformations of carbonyl-containing molecules derived from biomass, relevant for the production of perfumes, flavours and biofuels, will serve as examples for the critical evaluation of the catalytic performance of the M(IV) active sites inside the inorganic (zeolite) or metal–organic (MOF) crystalline framework.

MOF与沸石：具有M（IV）催化位点的羰基活化

该观点文章的目的是比较微孔沸石中良好分离的四价金属位点与金属-有机骨架的含氧金属节点中的四价金属位点的催化活性。几种酸（或酸碱）催化的源自生物质的含羰基分子的有机转化，与香水，香料和生物燃料的生产有关，将作为关键评估M（IV）活性物催化性能的实例。无机（沸石）或金属有机（MOF）晶体框架内部的位点。
