| 1. A method of preparing carbon nanocages, comprising:
introducing an inert gas into a reactor comprising a spray nozzle;
raising the temperature of the reactor to a pyrolysis temperature of a catalyst compound; and
spraying a reactant comprising the catalyst compound and a carbon-containing compound into the reactor through the spray nozzle,
wherein the ratio of a space velocity of the inert gas to a space velocity of the reactant is 100 or more.
