1. A method for preparing a carbon-supported and surface-engineered platinum nanocubes catalyst, said catalyst comprising:
a carbon-based support;
platinum nanocubes supported on the carbon-based support; and
individual iridium atoms with which surfaces of the platinum nanocubes are coated,
the method comprising the steps of:
preparing platinum nanocubes;
preparing carbon-supported platinum nanocubes by supporting the platinum nanocubes on carbon; and
preparing carbon-supported platinum nanocubes surface-coated with iridium atoms by coating the surfaces of the carbon-supported platinum nanocubes with iridium atoms.
