Logical Design for Replacement of Rh with Co in a Synergistic Catalyst for the Reduction of NO with H2

Catalysis Letters Aims and scope Submit manuscript

Abstract

Rhodium has been replaced in a synergistic Pt–Rh/γ-Al2O3 catalyst for the reduction of NO with H2 with a less expensive transition metal (Co). Performance in activity and selectivity was still better than Pt alone, thus synergy was again obtained. The nanoparticles in the Pt–Co catalyst were designed and tailored to mimic the microstructure of the synergistic Pt–Rh nanoparticles.
