Abstract

Provided is a method of preparing an intermetallic catalyst which includes applying ultrasonic wave to a precursor mixture solution including a noble metal precursor, a transition metal precursor, and a carbon support having an average pore size of about 6 nm to about 15 nm and a specific surface area of about 200 m/g to about 2000 m/g to form alloy particles in pores of the carbon support, and annealing the alloy particles in the pores of the carbon support to form intermetallic alloy particles.
