For the first time the phase-pure Pt0.5M0.5 (M = Fe, Co, Ni) solid solution and Pt-MOx metal-oxide composite model catalysts were synthesized via single-source precursors decomposition and evaluated in CO PROX. The remarkable synergetic effect of second metal (Fe, Ni, Co) addition was observed for both Pt0.5M0.5 and Pt-MOx systems. The synergism was associated with bifunctional nature of Pt0.5M0.5 and Pt-MOx catalysts and reaction occurrence at Pt-M interface. Pt-Co combination exhibited the highest activity in CO PROX. By the operando XRD technique the stability of Pt0.5Co0.5 unordered solid solution structure under CO PROX conditions was confirmed. While for Pt-Co3O4 metal-oxide composite Co3O4 reduction already at 50 °C was shown.
