在苯与乙烯的烷基化反应中，介孔沸石单晶催化剂表现出比传统沸石催化剂更强的活性和选择性。介孔沸石晶体的优良催化性能归因于其质量传递的改善。因此，介孔沸石单晶催化剂结合了高酸性、形状选择性和水热稳定性，以及介孔材料中通常实现的高效质量传递。
Mesoporous zeolite single-crystal catalysts are shown to be both more active and more selective than conventional zeolite catalysts in the alkylation of benzene with ethene. The superior catalytic properties are ascribed to improved mass transport in the mesoporous zeolite crystals. Thus, mesoporous zeolite single-crystal catalysts combine the high acidity, shape-selectivity, and hydrothermal stability of zeolites with the efficient mass transport that is typically achieved in mesoporous materials.
