英文摘要： Developing water-gas-shift catalysts is meaningful for easing energy crisis and environmental pollution, as well as the realization of efficient utilization of chemical resource. This project aims to develop water-gas-shift catalysts for the high concertration CO. Based on the structural and compositional design, apply the selective adsorption of CO feed gas directed synthesis techniques to synthesize highly active catalytic materials, and to further understanding the interactions between the reactant CO molecules and the surface of the catalysts. In-depth understanding the relationship between the structural properties of the catalysts, such as the composition, crystal structure, size, morphology, microstructure, the surface state and their catalytic properties, such as the activity, stability, and the sulfur resistance; the catalytic mechanism is investigated to elucidate the mechanism of synergy between the various components of the catalyst, and to guide the optimization of the catalyst structure, and to obtain water-gas-shift catalysts with good catalytic activity, stability and sulfur tolerant.
