Interface Engineering of Ru-Co3O4 nanocomposites for Enhancing CO Oxidation

Abstract

Interfacial structure plays an important role in heterogeneous catalysis due to its unique electronic structure. However, to design interfacial structures with high activity remains a challenge because the fundamental nature of the active catalytic sites and the details of the reaction mechanism are still hotly debated. Herein, we combine experiment and density functional theory calculations to reveal catalytic mechanism for the oxidation of CO by constructing a Ru-Co3O4 interface. Experimental results show that CO oxidation can be significantly enhanced over the interface. Density functional theory calculations indicate that this enhancement is attributed to the charge transfer from ruthenium to Co3O4. As a result, O2 is facilely activated by ruthenium with adjacent Co at the interface, hence lowering activation energy and boosting the catalytic performance of CO oxidation. This study provides a new way to design and develop efficient catalysts by engineering an appropriate interface.
