Recent Advances in the Development of Zeolite Catalysts for Propane Dehydrogenation: II. Cobalt-, Gallium-, Indium-, and Zinc-Containing Zeolite Catalysts (A Review)

The second part of the review (Bruter, D.V. and Konnov, S.V., Petr. Chem., 2025, vol. 65, pp. 331–368) is dedicated to the advances in the development of propane dehydrogenation catalysts based on cobalt-, gallium-, indium-, and zinc-containing zeolites. The existing strategies of the synthesis of materials based on molecular sieves are analyzed. In some cases, to reflect more completely recent advances in the development of metal-containing zeolite catalysts for dehydrogenation of lower alkanes, examples concerning ethane dehydrogenation, which is performed under harsher conditions are also presented, as well as oxidative dehydrogenation of lower alkanes with CO2. Particular attention is paid to studies of structure–property and synthesis–structure relationships. A brief conclusion summarizing the main results and unresolved problems is provided for each catalyst type in the end of the corresponding section. Conclusions regarding the most promising strategies for the development of industrial catalysts of new generation are presented in the final part of the review.
