Abstract
A porous catalyst includes at least one noble nano-metal particle, an oxide for forming porous structures, and a carrier material for supporting the oxide and the at least one noble nano-metal particle. The porous catalyst shows a large electrochemical surface area and a highly conductive ability. Further, the noble nano-metal particles are separated on the oxides uniformly, and the oxide of the catalyst forms a porous structure to provide a large electrochemical surface area. The porous catalyst provides excellent proton/electron transfer ability and increases the reaction rate.
Claims3
A method for producing a catalyst composition for a fuel cell, comprising:
- adding a carbon material and a metal oxide doped with nitrogen into an organic solvent with reductive ability to form a mixture;
- mixing the mixture;
- adding a precursor of a noble nano-metal particle into the mixture;
- heating the mixture containin the recursor of the noble nano-metal article to make precursor reduce to a noble nano-metal particle, wherein heating the mixture is provided as a recurrent flow heating method or a microwave heating method;
- and
- removing the organic solvent to obtain the catalyst composition.
