A stream of nitrogen carrier gas, saturated by precursor vapours in a saturator (Qs), was fed into the reactor, where it was mixed either with a stream of nitrogen (pyrolysis) or a mixture of nitrogen and air (oxidation). A stream of NPs laden gas (QR) was diluted in the outlet part of the work tube by a diluting stream (QDi|) of nitrogen (pyrolysis) or air (oxidation). The particle production was studied in dependence on reactor (fR) and saturator temperature (Ts), and on flowrates Qs, QR and Qoii, and NPs production was monitored using SMPS (TSI model 3936L75). Samples for NPs characterization were deposited onto TEM grids, using a nanometer aerosol sampler (TSI model 3089) and on cellulose, quartz, and Sterlitech Ag filters. The particle characteristics were studied using HRTEM (JEOL 3010), energy dispersive spectroscopy (.INCA/Oxford connected to JEOL 3010), selected area electron diffraction (JEOL 3010), inductively coupled plasma - optical emission spectrometry (Agilent 4200 MP-AES), elemental and organic carbon analysis (EC/OC, Model 4, Sunset Laboratory) and X-ray diffraction (Bruker D8 Discover diffractometer).
