Advances in Catalytic Applications of Zeolite‐Supported Metal Catalysts

“…Besides the C1 chemicals, aromatics, and light olefins, the bifunctional catalysts could be used as highly efficient catalysts to produce diverse chemicals, such as gasoline, [ 52 ] liquefied petroleum gas, [ 83 ] and higher alcohols. [ 25b ] Sun and co‐workers prepared a series of bifunctional catalysts comprising Na–Fe 3 O 4 NPs and various zeolites, such as 12‐MRs zeolites ZSM‐23 (MTT), MCM‐22 (MWW), ZSM‐5, zeolite‐Y, Beta, and MOR.…”

Improvement of adsorption and catalytic properties of zeolites by precisely controlling their particle morphology

“…The resultant Pd/SiO 2 @silicalite-1@ZSM-5 gives a selectivity to liquefied petroleum gas (LPG) of 35.6%, to methanol of 5.9% and to DME of 19.3% in CO 2 hydrogenation. 22 It is shown that methanol is formed on Pd@SiO 2 , and subsequently dehydrated to DME and converted to hydrocarbons on the zeolite.…”

“…19,20 Metal nanoparticle core@zeolite shell materials are potential candidates for one-step realization of tandem reactions such as the Fischer-Tropsch selective synthesis of gasoline, jet fuel and diesel fuel. [21][22][23] In addition, they show a long catalytic life in some high-temperature reactions such as propane dehydrogenation to propene as a result of effective suppression of agglomeration of metal nanoparticles by the zeolite shell. 24,25 Certainly, the catalytic performance is closely related to the metal nanoparticle's size and zeolite's structure, acidity, chemical composition and shell thickness.…”

Thermocatalytic hydrogenation of CO2 into aromatics by tailor‐made catalysts: Recent advancements and perspectives

“…Until now, several pathways for targeted products synthesis from CO 2 hydrogenation have been proposed, such as the liquid petroleum gas (LPG) synthesis on capsule catalyst Pd/SiO 2 @S‐1@H‐ZSM‐5, 40 light olefins synthesis via ZnGa 2 O 4 /SAPO‐34 or ZnO‐ZrO 2 /SAPO‐34, 30,41 transportation fuels or aromatics synthesis using reducible metal oxide (ZnO‐ZrO 2 and In 2 O 3 ‐ZrO 2 ) or Fe‐based catalyst combined with H‐ZSM‐5 zeolite 31,32,42,43 . It is obvious that reducible metal oxides for methanol synthesis from CO 2 hydrogenation have been widely employed for the rational design of bifunctional/multifunctional catalysts because the significant advancements in methanol conversion (MTA‐methanol to aromatics, MTG‐methanol to gasoline, and MTO‐methanol to olefins) guaranteed the success of oriented CO 2 conversion to aromatics, light olefins, or gasoline‐range hydrocarbons via the methanol‐mediated pathway.…”
