Abstract:
A method for preparing a metal catalyst supported on a porous carbon support using a plant, including: (a) a step of preparing a plant; (b) a step of preparing a metal precursor-absorbed plant by absorbing a metal precursor into the plant; (c) a step of preparing a catalyst precursor by drying the metal precursor-absorbed plant; (d) a step of preparing a char by charring the catalyst precursor; and (e) a step of preparing a metal catalyst supported on a porous carbon support by treating the char with an acid. The method for preparing a metal catalyst supported on a porous carbon support of the present disclosure, whereby a plant itself is charred, is environment-friendly and allows for convenient large-scale synthesis. The metal catalyst supported on a porous carbon support prepared thereby can be used as electrode materials of various energy devices, particularly as an electrode catalyst of a fuel cell.

Claim (Index 9):
The method for preparing a metal catalyst supported on a porous carbon support using a plant according to  claim 1 , wherein a metal comprised in the metal precursor is one or more selected from cobalt (Co), platinum (Pt), palladium (Pd), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), vanadium (V), chromium (Cr), nickel (Ni), gold (Au), silver (Ag), zinc (Zn), rhodium (Rh) and ruthenium (Ru).
