Hydrothermal Synthesis of Metal Oxide Nanoparticles in Supercritical Water
This paper summarizes specific features of supercritical hydrothermal synthesis of metal oxide particles. Supercritical water allows control of the crystal phase, morphology, and particle size since the solvent's properties, such as density of water, can be varied with temperature and pressure, both of which can affect the supersaturation and nucleation. In this review, we describe the advantag...
متن کاملGeneral approach for the synthesis of organic-inorganic hybrid nanoparticles mediated by supercritical CO2.
We report in this paper novel chemistry that addresses the problem of surfactant solubility in supercritical CO2 for metal nanoparticle synthesis. This new approach for the preparation of organic-functionalized inorganic nanoparticles relies on the reduction of a metal precursor in a CO2-containing insoluble polymer. Reduction of the metal with H2 leads to small nanocrystals stabilized by the p...
متن کاملPopulation Balance Modelling of Zirconia Nanoparticles in Supercritical Water Hydrothermal Synthesis
Like any other precipitation process, in supercritical water hydrothermal synthesis (SWHS), the need to improve product quality and minimize production cost requires understanding and optimization of Particle Size Distribution (PSD). In this work, using Population Balance Equation (PBE) containing nucleation and growth terms, the reactive precipitation of zirconia nanoparticles prepared by ...
متن کاملHydrothermal synthesis of inorganic-organic hybrid gadolinium hydroxide nanoclusters with controlled size and morphology.
A series of gadolinium hydroxide [Gd(OH)3] nanoclusters having different morphologies was synthesized in the presence of 3,4-dihydroxy hydrocinnamic acid (DHCA), an organic modifier, under subcritical water conditions. These well-shaped Gd(OH)3 clusters are composed of many nanorods in a parallel orientation, rather than a disordered aggregation of nanorods, which are linked together by organic...
متن کاملIntroduction, synthesis procedures, and applications of organic-inorganic hybrid nanoflowers in biosciences
Organic-inorganic hybrid nanoflowers with flower-like morphology are new nanostructures comprising organic and inorganic components. In general, the organic component of hybrid nanoflowers mostly consists of proteins, DNA, RNA, plant extracts, metabolites, and natural polymers; and the inorganic component composes of various metal phosphates, including copper, calcium, manganese, iron, zinc, co...
