Interaction of CO with CuO and CuO/graphene: Reactions Mechanism and the Formation of CO2
CuO/graphene oxygen carrier models were built to investigate the reaction stoichiometry mechanism between the fuel gas CO and oxygen carrier CuO. The results show that the energy barrier of the single metal oxide CuO oxidation CO is 127.17kJ/mol, while energy barrier is only 42.64 kJ/ mol for the CuO/graphene. From the point view of chemical reaction dynamics, the oxidation activity of CuO/graphene much higher than single-metal oxide CuO, which indicate that graphene can improve the reaction performance of oxygen carrier. And analysis results for the oxidation of fuel gas CO has an important understanding of the process of scientific significance, and will promote the fundamental understanding and applications of the oxygen carrier CuO.
