Abstract and Keywords

Abstract: In this work, porous carbon nanospheres were synthesized by ultrasonic spray pyrolysis using sucrose. The technological conditions of synthesis were investigated, and the optimum synthesis conditions are $ 800\ ^{\circ}C $ and carrier gas flow rate of 2.0 L/min. The synthesized porous carbon material has regular spherical shape, with the particle size of 600-1500 nm and abundant internal pores with the diameter of 50-100 nm. And composite porous carbon nanospheres with aluminum, cobalt, copper, zinc, nitrogen, carbon nanotubes and nano titanium dioxide were easily prepared by adding different metal and non-metal precursor materials into the precursor solution. This work is beneficial to the simple design and rapid synthesis of advanced carbon nanomaterials.

Keywords: ultrasonic spray pyrolysis; porous carbon; nanosphere; composite material
