利用定性和定量模型，包括短程和长程效应，在理解沸石酸性方面取得了进展，但在使用探针分子测量酸性方面仍然存在局限性。概述了利用MCM-41结构扩大沸石孔的优点和局限性。在提高杂多酸和ZrO 2/SO 42 −的催化活性以及解决ZrO 2/SO 42 −催化烃反应的机理方面取得了重大进展。最后，在有机-无机复合物（磷酸锆和膦酸锆、聚硅氧烷、Nafion-二氧化硅）的制备及其作为酸催化剂的潜力方面也取得了新的进展。
Abstract Using qualitative and quantitative models, including both short and long range effects, progress has been made in understanding acidity in zeolites, but limitations that still exist in measuring that acidity by use of probe molecules. The benefits and limitations of enlarging zeolite pores by means of MCM-41 structures have been outlined. Major advances have been made in improving the catalytic activity of heteropolyacids and ZrO2/So42−, as well as tackling the mechanism through which ZrO2/SO42− catalyzes hydrocarbon reactions. Finally, new advances have also been made in the preparation and potential as acid catalysts of organic—inorganic composites (Zr phosphates and phosphonates, polysiloxane, nafion—silica).
