In Situ observation of SnO2 nanoparticle formation in the gas phase

We propose an in situ experiment combining small and wide angle X-ray scattering (SAXS & WAXS) to probe the formation process of SnO2 nanoparticles (NPs) by chemical vapor synthesis (CVS) in the gas phase. Utilizing the high-brilliance of ESRF’s ID02 beamline, the formation process within highly diluted aerosols of NPs will be accessible from the first steps of nucleation and growth via agglomeration to the fully developed NP. This experiment on the model system SnO2-NP will widen our understanding of gas-phase based NP formation processes on the nanoscale in general and will find applications on other technological relevant nanoparticle systems.
