Özet

The reduction of metal nitrates (Cu(NO3)2 · 6H2O, AgNO3, and Ni(NO3)2 · 6H2O) by polyols under hydrothermal conditions at temperatures of 150-250 C was studied. The possibility of synthesizing copper, silver, and nickel powders with average particle sizes of 10 to 150 nm depending on the concentration of initial reagents, the temperature, and the nature of a reducer was established using X-ray diffraction analysis and atomic force microscopy. Lanthanide and alkali-earth nitrates were shown to form highly dispersed powders of metal carbonates with an average particle size of ∼23 nm under similar conditions. © 2013 Pleiades Publishing, Ltd.
