Metal oxides and their roles in heterogeneous catalysis: special emphasis on synthesis protocols, intrinsic properties, and their influence in transfer hydrogenation reactions

Abstract

Abstract This review emphasizes La-based metal oxides of the perovskite form and their application in heterogeneous catalytic transfer hydrogenation (CTH) reactions from year 2013. Perovskites are potential alternatives to noble metals. The possibility of induced-synergy between two cations in the ABO3 or multicationic perovskites makes them attractive for hydrogenation reactions. Herein, we look at recent developments in their synthesis protocols, and how the various physicochemical properties derived from the individual synthesis protocols affect the catalytic performances of perovskite oxides in transfer hydrogenation reactions. Furthermore, we review different type of perovskite-based catalysts and the mechanisms of the surface catalyzed transfer hydrogenation reactions.
