Method for fabricating hollow metal nano particles supported on carrier

A method for fabricating catalyst comprising hollow metal nano particles supported on a carrier, the method comprising:

• forming a solution by adding a first metal salt, a second metal salt, and a surfactant to a solvent which consists of water;
• forming hollow metal nano particles having an average particle diameter of 30 nm or less by adding a reducing agent to the solution;
• and
• supporting the hollow metal nano particles on a carrier,
• wherein the forming of the solution comprises forming a micelle by the surfactant, and surrounding the outside of the micelle by the first metal salt and the second metal salt,
• the forming of the hollow metal nano particles comprises forming the micelle region to a hollow form, and
• a concentration of the surfactant in the solution is 0.2 time to 5 times a critical micelle concentration (CMC) to water.
