Remote Activation Catalysis: Interparticle Hydrogen Spillover-Assisted Cumene Synthesis from Propane and Benzene.

ABSTRACT: Hydrogen spillover, particularly when involving "interparticle" hydrogen spillover, offers a unique opportunity to enhance catalytic efficiency by remote activation of surface acidity. Building on this concept, this study aims to investigate physically mixed alumina-supported platinum nanoparticles (Pt/Al₂O₃) and zirconia-supported tungsten oxide (WO₃/ZrO₂) in promoting the direct synthesis of cumene from benzene and propane at 300 °C. The reaction with Pt/Al₂O₃ alone afforded propylene as the only product, indicating the successive reaction route of Pt-catalyzed dehydrogenation of propane, followed by acid-catalyzed alkylation. WO₃/ZrO₂ with 18 wt.% WO₃ loading resulted in high benzene conve
