“…This study represents critical research focusing on the SMSI effect in terms of catalytic activity, as opposed to the conventional consideration of the SMSI effect in terms of durability. Considering the tightening of fuel efficiency regulations and the future promotion of electrification, the thermal durability requirements for gasoline-powered vehicles should be relaxed . Therefore, in future automotive catalysts, exploiting the optimum SMSI effect with respect to improving catalytic activity rather than durability should be necessary.…”

In precious metal catalysts, the interaction between the precious metal and oxide support, denoted the strong metal–support interaction (SMSI), is closely related to catalytic activity. However, there are few studies of the effects of the SMSI on catalytic activity and the properties of catalytic active sites. Therefore, the valence band spectra of Rh catalysts on various supports were measured using X-ray photoelectron spectroscopy and a more surface-sensitive experimental technique, extreme ultraviolet-excited photoelectron spectroscopy. There is a good correlation between the catalytic activities of these Rh catalysts in the CO–NO reaction and the energy difference between the peaks of the Rh metal and Rh2O3 components in the valence band spectra. The cause of the difference in the activities of the Rh catalysts on various supports is analyzed based on density functional theory calculations using two models: Rh metal/support and Rh2O3/support. Rh metal and Rh2O3 contribute to the activity of the CO–NO reaction. NO dissociation is promoted on the Rh metal surface, where the SMSI induces enhanced oxygen adsorption. Conversely, CO oxidation is promoted on the Rh2O3 surface, where the oxygen bonding is weakened by the SMSI. This study reveals the critical mechanisms whereby SMSIs contribute to oxygen-mediated reactions on catalyst surfaces.

“…The durability and reactivity of the catalyst vary considerably depending on the combination of the PGM and support material. Catalyst durability, in particular, is critical in satisfying the emission regulations of each country, and thus, several studies focusing on catalyst durability are reported.…”
