With the aim of understanding the thermochemistry of the introduction of mesoporosity in zeolites by using surfactants, high temperature oxide melt solution calorimetry was used to determine the change in the enthalpy of formation of USY zeolite before and after the introduction of mesoporosity. Our results confirm that this process only slightly destabilizes the zeolite by the additional surface area. However, this can be overcome by the stabilizing effect of the interactions between the surfactant and the zeolite framework.
为了理解通过使用表面活性剂在沸石中引入介孔的热化学，采用高温氧化物熔体溶液量热法来测定引入介孔前后超稳Y型沸石生成焓的变化。我们的结果证实，该过程仅因增加的表面积而使沸石略微不稳定。然而，这可以通过表面活性剂与沸石骨架之间相互作用的稳定作用来克服。
