| 英文摘要 | Dry reforming of methane (DRM) is an effective route to convert methane and carbon dioxide to syngas. Herein, we report an efficient nickel cobalt bimetallic catalyst with an activity of 4.97 mol(CH4) mol(Ni)(-1)s(-1) at 800 degrees C. It is active at low temperature as well, and near thermodynamic equilibrium conversion was achieved as low as 350 degrees C, with a high yield of H-2 implying inhibition of side reactions: i.e., a reverse water-gas shift (RWGS) reaction. The formation of Ni-Co alloy during the reaction was observed, and its lattice contraction was revealed by HAADF-STEM and EXAFS experiments. The lattice-strained Ni-Co alloy has good CO2 dissociation ability, which is responsible for its superior catalytic performance. Its weak chemisorption with H-2 results in inhibition of RWGS side reactions. This work is helpful in the design and development of other metal alloy materials with novel structures and/or electronic configurations for catalytic applications. |
