METHOD FOR PREPARING CARBONIZED MESOPOROUS BLOCK COPOLYMER PARTICLE, CATALYST COMPRISING CARBONIZED MESOPOROUS BLOCK COPOLYMER PARTICLE PREPARED BY THE SAME AND CATHODE MATERIALS OF FUEL CELL COMPRISING THE CATALYST

摘要

The present invention relates to a method for producing carbonized mesoporous block copolymer particles, a catalyst comprising the carbonized mesoporous block copolymer particles, and a fuel cell negative electrode material comprising the catalyst, one embodiment of the present invention A method for producing carbonized mesoporous block copolymer particles according to an example includes: preparing a dispersion phase and a continuous phase to form emulsions; Forming an emulsion droplet by passing the emulsion through pores of a Shirasu porous glass (SPG) membrane; Separating the droplets formed on the membrane surface into a continuous phase; Evaporating the solvent in the emulsion to form block copolymer (BCP) particles; Forming a porous hyper-block copolymer particle by hyper-crosslinking and selectively etching the block copolymer particle; And doping and then carbonizing the porous hyper block copolymer particles with metal atoms to form metal atom/carbonized block copolymer particles. And thermally reducing the metal atom/carbonized block copolymer particles by dissolving them in a mixture containing a platinum precursor.
