Title : CO oxidation over Au catalysts supported on CuO/Cu2 O both in O2 - rich and H2 - rich streams: Necessity of copper oxide
In this work we prepared nanometer copper oxide and cuprous oxide with different morphologies followed by the deposition of Au nanoparticles. The reaction of CO oxidation in both hydrogen-rich and oxygen-rich streams was investigated over as-prepared CuO/Cu2O materials and the corresponding supported Au catalysts. A comprehensive analysis of the catalytic results demonstrates that CuO species not Cu2O play much more critical role as the active sites for the oxidation of CO and the synergistic enhancement in catalytic activity can be realized via its strong interaction with nanogold particles.
Audience Take Away:
- The audience will see why and how our catalytic system reveals the high catalytic performance by using the appropriate catalyst physicochemical characteristics.
- The audience will know why and how the cooperation effect between CuO and nanogold were confirmed and played an important role for the high performance of present catalytic system.
- Our work may help the audience who work in the same topic to design a better catalyst for CO-PROX reaction.
- This research can be used by others to expand their research.
