Strong metal-support interactions of TiO₂ interface-loaded Pt constructed under different atmospheres for adjusting the hydrogen storage reaction performance of N-ethylcarbazole.

ABSTRACT: In this study, two series of samples (rT-Pt/TiO₂ prepared with a hydrogen pretreatment and Tr-Pt/TiO₂ prepared with an oxygen pretreatment) were prepared by treating commercial TiO₂ supports in different atmospheres to establish different TiO₂ interfacial structures, followed by the addition of platinum nanoparticles (NPs) for the catalyzed hydrogenation/dehydrogenation cycle of N-ethylcarbazole (NEC). The kinetic analysis and reaction mechanism were investigated by combining XRD, Raman, CO-DRIFT, HRTEM, XPS, H₂-TPD and DFT calculations. It was found that the performance of the samples for the NEC system's cyclic hydrogen storage could be modulated by treating the TiO₂ interfacial structure with differen
