Abstract:
1. A method of precipitating nanoparticles in a continuous hydrothermal or solvothermal process by the mixing of a precursor, which consists essentially of an aqueous solution or suspension of solid particles for the production of nanoparticles, with a fluid for the production of nanoparticles, the fluid containing water or a mixture of water and solvents other than water and being substantially at or above the critical point of the fluid in a co-current mixer having unidirectional flow from coaxial inner and outer inlets to an outlet via a mixing zone immediately downstream of said inlets, the method comprising the steps of: providing a fluid flow of the precursor to the outer inlet, providing a fluid flow of the fluid to the inner inlet, and precipitating nanoparticles by mixing of the precursor with the fluid in said mixing zone.
