Aerosol Synthesis and Deposition Technologies as a Production Platform for Nanoparticles and Nanostructures
In aerosol nanoparticle synthesis routes, a liquid precursor solution is atomized into fine droplets that are passed through a high-temperature reactor zone where they are transformed within a very short time to ultra-fine particles of the desired powder. In this way, each individual droplet becomes a micro-reactor, where homogeneous mixing of the precursor materials is achieved. Aerosol routes are characterized by very short synthesis times and extremely high cooling rates and therefore are capable of producing particles with high concentration of defects, known to have a beneficial effect on surface chemical reactions; they have potential for nano-particle synthesis, amenability to scale-up and last but not least, in contrast to wet-chemistry methods that are composition-specific, are extremely flexible: a wide variety of compositions can be synthesized with the same experimental configuration. Aerosol technologies are thus ideally suited for large-scale, cost-effective, nanoparticles synthesis consistently and correctly controlled at the nano-scale, in a safe, environmentally friendly manner, since on the one hand they are inherently capable for continuous nanoparticle synthesis with good reproducibility in a controlled manner reducing the emission of pollutants to the environment and on the other hand they can be scaled-up and incorporated into traditional chemical manufacturing processes.
