PURPOSE: A transition metal-silica yoke-shell nano particle catalyst for a carbon-carbon coupling reaction, and a performing method of the carbon-carbon coupling reaction thereof are provided to improve a diffusivity and accessability of the reactants by empty spaces among the transition metal-silica and the pores in the silica shell. CONSTITUTION: A transition metal-silica yoke-shell nano particle catalyst for a carbon-carbon coupling reaction is surrounded by a silica shell that nano particles of VIII group-transition metal have pores, and has a form of nano particle structure which has empty spaces among the transition metal and the nano particles. The transition metal is an alloy of one or two metals selected among Pd, Ni, and Pt. The content of transition metal in the nano particle catalyst is 0.5-20wt%. The size of catalyst is 10-100 nm. The thickness of the empty space layer is 1-50 nm. |
