Nanometerization of liquid metal (e.g., EGaIn consisting of ≈75 wt% gallium and ≈25 wt% indium [1]), which can uniquely combine the nonvolatile metallic properties, fluidic feature,

Lv et al.Ni-Based Catalysts CO 2 Methanation auxiliaries and dopants, the fabrication methods, reaction conditions, etc. Finally, the future development trend of the Ni based catalysts is also prospected, which will be helpful to the design and fabrication of the Ni catalysts with high efficiency toward CO 2 methanation process.
