Abstract
Disclosed are a double metal-carbon nanotube hybrid catalyst comprising at least two of transition metals selected from a group consisting of Mn, Fe, Co, Ni, Cu, Mo, Tc, Ru, Rh, Pd, Ag, Re, Os, Ir and Pt which are distributed in the catalyst. The double metal-carbon nanotube hybrid catalyst contains at least two different transition metals with high catalytic activity and may generate hydrogen from an aqueous ammonia-borane (NH3BH3) solution at a high speed and a method for preparation of a double metal-carbon nanotube hybrid catalyst.

A double metal-carbon nanotube hybrid catalyst comprising at least two of transition metals selected from a group consisting of Mn, Fe, Co, Ni, Cu, Mo, Tc, Ru, Rh, Pd, Ag, Re, Os, Ir and Pt which are distributed in the catalyst.
A method for preparation of a double metal-carbon nanotube hybrid catalyst, comprising:
- adding nitrogen doped carbon nanotube (NDCNT) to a polyol solution to prepare a carbon nanotube solution;
- adding at least two of transition metal salts as well as sodium borohydride (NaBH4) to the prepared carbon nanotube solution to return the carbon nanotube by reduction thereof;
- and
- thermally treating the reduced carbon nanotube under hydrogen atmosphere after vacuum drying the same, so as to form the double metal-carbon nanotube hybrid catalyst.
