“…and various supports (SiO 2 , TiO 2 , Al 2 O 3 , La 2 O 3 , ZSM-5 zeolite) [7,8]. Mixed metal catalysts are often capable of activity, selectivity, or have a stability, that is unobtainable with a single component [9] and it is believed that bimetallic catalysts system due to the thermodynamic and kinetic limitations of the reaction are more able to raise the value of the light olefins [10][11][12][13].…”
