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

In this study, two series of samples (r-Pt/TiO prepared with a hydrogen pretreatment and r-Pt/TiO prepared with an oxygen pretreatment) were prepared by treating commercial TiO supports in different atmospheres to establish different TiO interfacial structures, followed by the addition of platinum nanoparticles (NPs) for the catalyzed hydrogenation/dehydrogenation cycle of -ethylcarbazole (NEC). The kinetic analysis and reaction mechanism were investigated by combining XRD, Raman, CO-DRIFT, HRTEM, XPS, H-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 TiO interfacial structure with different atmospheres varying the extent of strong metal-support interaction (SMSI).
