Many successful methods for nanoparticle synthesis are based on a comminution of the phases containing the precursors prior to the chemical reactions. The beneficial effects of such techniques are well-known in terms of small dimensions and narrow distributions of diameters of the nanoparticles thereby produced. According to specific methods, micelles or droplets behave as segregated micro-reactors where reactants are made to combine with minimization of further aggregation, to improve the quality of the final product. In the present paper, an aqueous solution of a reagent is nebulized on the surface of a stirred liquid containing the second reagent, with formation of a nanosized solid phase with diameter and height ranges of 50-100 nm and 6-8 nm, respectively. We are not aware of other wet-chemical methods based on such a technique, which proves to be simpler and more inexpensive than the typical one of traditional spray processes followed by high-temperature pyrolysis, which are generally carried out in flame reactors. |
