Due to its high external surface area and large external acid concentration, MCM-56 zeolite exhibits excellent potential catalytic performance in alkylation of aromatics. However, it's a transient product and momentarily convert into MCM-49 zeolite. Herein, we present a facile strategy for stable ...
