Zeolite crystals with an embedded and interconnected macropore system are prepared by using mesoporous silica particles as a silica source and as a sacrificial macroporogen. These novel hierarchical zeolite crystals are expected to reduce diffusion limitations in all zeolite-catalyzed reactions, especially in the transformation of larger molecules like in the catalytic cracking of polymers and the conversion of biomass.
采用介孔硅颗粒作为硅源和牺牲大孔剂，制备了具有嵌入式互联大孔体系的沸石晶体。这些新型的分级沸石晶体有望减少所有沸石催化反应中的扩散限制，特别是在聚合物催化裂化和生物质转化等较大分子的转化中。
