Formation mechanism of surface modified iron oxide nanoparticles using controlled hydrolysis reaction in supercritical CO2

Low temperature synthesis of ZnO particles using a CO2-driven mechanism under high pressure

“…21 Additionally, scCO 2 has high solubility of metal organic precursor and high diffusivity while the synthesis in scCO 2 is substantially solventless process because scCO 2 is easily removed only by reducing the pressure. 22,23 Furthermore, it is revealed in our recent research that scCO 2 can be used as not only synthesis medium but also washing and drying solvents for the particle production. 24 These appealing characteristics enable the simple production process without using an organic solvent and a post-treatment.…”
