Abstract: Provided is a method of preparing a heteroatom-doped carbon nanomaterial. The method includes preparing a dispersion solution by dispersing a carbon nanomaterial in a solvent, forming first droplets by spraying the dispersion solution via an ultrasonic spray nozzle, and forming second droplets including a heteroatom-doped carbon nanomaterial by supplying a gas to the first droplets to dope the first droplets with an element included in the gas.
