Porous Carbon Powders Prepared by Ultrasonic Spray
New, thermally robust meso and macroporous carbon powders were prepared by ultrasonic spray pyrolysis (USP) of aqueous solutions using an inexpensive highfrequency ultrasound generator from a humidifier. We choose our molecular precursors rationally, so that the expected decomposition pathways produce only remnant carbon atoms. Specifically, our rational design criterion led to
