Flame aerosol reactor with two-phase nozzle for atomization of the liquid precursor solution and cylindrical torus ring for injection of C2H2 or premixed CH4/O2 in flame-assisted spray pyrolysis (FASP) configuration. The ring can be placed at various heights above the nozzle (HAN) of 0.5–3 cm. Optionally, the spray could be surrounded by a shielding tube placed between the burner face and the FASP ring to prevent air entrainment
