Silica‐encapsulated <scp>Co</scp> / <scp>BEA</scp> core–shell catalysts for <scp>PDH</scp> : Stabilizing tetrahedral <scp> Co
Propylene is a key chemical. Propane dehydrogenation (PDH) over non‐noble cobalt catalysts suffers rapid deactivation from sintering and coking. Herein, we report a core–shell catalyst (1.0Co/BEA@ x Si) with a mesoporous silica shell on Co‐impregnated dealuminated Beta zeolite. The silica shell enhances Co disper...
