Abstract
Many oxide/oxide composite nanocrystals were synthesized in continuous flow SCW processes in short time (e.g., 0.4 s∼2 min) from metal cations via hydrolysis and subsequent dehydration. Metal particles could be produced by further reduction of the metal oxide in SCW. These particles included ferrite magnetic pigments [Fe3O4, MFe2O4 (M = Co, Ni, Zn), NixCo1−xFe2O4, \({\textrm {BaO}}{\scriptscriptstyle{\bullet}}6{\textrm{Fe}}_{2} {\textrm{O}}_{3}\)] for recording media, YAG: Tb phosphor for cathode ray tube screen, materials (LiCoO2, LiMn2O4) for lithium ion battery cathode, catalysts for car exhausts [Ce1−xZrxO2 (x = 0∼1), Zr1−xInxO2, Zr1−xYxO2], oxidation (La2CuO4) and gasification (ZrO2, CeO2, Ni), photocatalytic materials (K2Ti6O13, ZnO, TiO2) for water decomposition, materials (SnO2, ZnO, In2O3) for electronics industry, supporting materials (AlOOH) for catalysts, and many other oxides. Oxides were also produced in batch reactors for long reaction time but with larger size. Organic capping ligands were successfully used to control and stabilize particles size (TiO2, Fe2O3, Cu, CeO2). Oxide nanoparticles could also be synthesized via other chemical reactions in SCW.
