Abstract
AbstractNon‐oxidative dehydrogenation of propane is a highly efficient approach for industrial preparation of propene that is commonly catalyzed by noble Pt or toxic Cr catalysts and suffers from coking. In this work, ferric catalyst confined in a zeolite framework was synthesized by a hydrothermal procedure. The isolated Fe in the framework formed distorted tetrahedra, which were beneficial for the selective dehydrogenation of propane and reached over 95 % propene selectivity and over 99 % total olefins selectivity. This catalyst had a silanol‐free structure and was oxygen tolerant, hydrothermally stable, and coke free, with a deactivation constant of 0.01 h−1. This study provided guidance for the synthesis of structural heteroatomic zeolite and efficient propane non‐oxidative dehydrogenation over early transition metals.
