Porous carbon spheres with unique structures and morphologies are prepared from energetic carbon precursors, alkali propiolates, via ultrasonic spray pyrolysis. Aerosolized liquid droplets containing alkali propiolates act as microreactors that confine the thermal decomposition of energetic precursors and lead to the formation of several unprecedented carbon morphologies.
