Hydrothermal Synthesis of Metal Oxide Nanoparticles in Supercritical Water

“…To achieve the control of the solvent field during nucleation and crystallization of particles, hydrothermal conditions of temperature and pressure can be varied in subcritical and supercritical water. Hydrothermal methods for preparing fine metal oxide particles in subcritical and supercritical water have been developed using batch reaction [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 ] and flow reaction systems [ 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58...…”

Low‐Temperature Synthesis of YVO4 Nanoparticles and their Photocatalytic Activity

“…Previously, many techniques have been developed to synthesize YVO 4 crystallites, including high‐temperature solid‐state reaction, 18 liquid‐phase reaction and precipitation technique, 19,20 microwave irradiation and combustion reaction, 21,22 hydrothermal processing and supercritical water method, 15,23 and hydrolyzed colloid reaction technique 24 . Nonetheless, how to synthesize well‐crystallized YVO 4 nanoparticles under a simple and convenient condition is still a big challenge.…”
