A bimetallic strategy to modulate electronic metal support interaction in Co 3 O 4 (111)-based catalysts: the case of supported Rh–Pt core–shell nanoparticles
Abstract
(111) thin films on an Ir(100) substrate and investigated using synchrotron radiation photoelectron spectroscopy. We found that incorporating Pt, either as the core in Pt@Rh or as the shell in Rh@Pt nanoparticles, significantly attenuates charge transfer, thereby stabilizing Rh in its metallic state and suppressing disintegration of the core@shell nanoparticles. This stabilization is attributed to strong Rh-Pt interaction and the ability of the two metals to form stoichiometric binary phases. These findings demonstrate that bimetallic interactions offer an effective strategy to tune EMSI, providing a fundamental basis for the design of electronically balanced and thermally stable catalysts supported on reducible oxides.
