摘要:A simple approach to produce mixed Cu/Cu 2 O nanocrystals having a specific morphology by controlling the reaction temperature during Cu/Cu 2 O nanocrystals synthesis. Other variables are kept constant, such as the amount of reactants, while the reaction temperatures is maintained at a predetermined temperature of 70° C., 30° C. or 0° C., which are used to produce different and controlled morphologies for the Cu/Cu 2 O nanocrystals. The reaction mixture includes a copper ion contributor, a capping agent, a pH adjustor, and reducing agent. The reaction mixture is held at the predetermined temperature for three hours to produce the Cu/Cu 2 O nanocrystals. The synthesis method has advantages such as mass production, easy operation, and high reproducibility.

摘要:The present invention relates to the technical field of animal feed production, and particularly discloses a preparation method using crystal modification in the synthesis of basic cupric chloride. The preparation method comprises the following steps: adding copper chloride into a reaction kettle at room temperature, then adding tap water, and fully stirring same until the copper chloride is completely dissolved; then adding a polymer crystal improver to the reaction kettle, and continuing to stir same after the polymer crystal improver is totally added; then adding a sodium hydroxide solution, continuing to stir same after the sodium hydroxide solution is totally added, and then leaving same to stand; then opening the bottom of the reaction kettle, transferring same to a vacuum suction filtration device for suction filtration to obtain a solid, cleaning same with tap water, and putting same into a drying box after suction filtration is completed, and drying same at a constant temperature; and subjecting the product resulting from drying to a simulated high-temperature and high-humidity test in a constant-temperature and constant-humidity test box. The preparation method is simple in terms of process and convenient to operate, has high yield and low cost, and causes no environmental pollution, and the prepared product is stable and hardly gets damp under high-temperature and high-humidity conditions.

摘要:Process for the synthesis of nanoparticles comprising oxidation sensitive metals, in particular copper comprising the following steps: n- Preparation and nucleation of citrate-capped Metal-hydroxide nanoparticles, n- reduction of the intermediate citrate-capped Metal-hydroxide nanoparticles to Metal 0 by reduction via NaBH 4 n Cu 0 nanoparticles with narrow size distribution are obtained by NaBH 4 -induced reduction of CuCl 2 ·2H 2 O in diethylene glycol. The course of the reaction essentially involves an intermediate formation of Cu(OH) 2 nanoparticles as well as the presence of citrate to control the nucleation of almost monodisperse and non-agglomerated Cu 0 nanoparticles. The citrate-capped Cu 0 nanoparticles of the invention are surprisingly stable against air oxidation. Via simple solvent evaporation, porous Cu 0 thin-films are prepared on glass substrates that exhibit bulk-like sheet resistances of 0.23 - 0.42 Ω â–¡ after vacuum sintering at 250 °C (bulk-Cu sheet under similar conditions with: 0.3 Ω â–¡ ). With these features the as-prepared, citrate-capped Cu 0 nanoparticles become highly relevant to electronic devices in particular thin-film electronics, thin-film sensors and high-power batteries.
