A facile method for designing and synthesizing nanostructured carbon particles via ultrasonic spray pyrolysis of a self-organized dual polymer system comprising phenolic resin and charged polystyrene latex is reported. The method produces either hollow carbon particles, whose CO₂ adsorption capacity is 3.0 mmol g^鈥?, or porous carbon particles whose CO₂ adsorption capacity is 4.8 mmol g^鈥?, although the two particle types had similar diameters of about 360 nm. We investigate how the zeta potential of the polystyrene latex particles, and the resulting electrostatic interaction with the negatively charged phenolic resin, influences the particle morphology, pore structure, and CO₂ adsorption capacity.
