A uniform pore size with a highly ordered structure is still observed for zeolite (ZSM‐5)‐coated mesoporous aluminosilicates (ZCMesoAS) even after the coating procedure (see transmission electron micrograph). These ZCMesoAS, which are hydrothermally ultrastable and highly acidic owing to the nanocrystalline zeolitic nature of their pore wall surface, are produced from diluted clear solutions containing primary zeolite units. The novel features of ZCMesoAS open new possibilities for their use as acid catalysts.
