Paired aluminum sites in zeolite catalysts enhance aromatics production

摘要

In this issue of Chem Catalysis, Ruiz-Marti PRIME;nez and co-workers inves-tigate the effect of aluminum (Al) proximity and distribution on acid-catalyzed reactions in zeolites. They find that Al enrichment near the external surface results in paired acid sites that exhibit enhanced ac-tivity for aromatics formation.
