Synthesis of CuO Nanocrystals in a Water-Isopropanol System
A facile method capable of preparing CuO nanocrystals has been developed in a water-isopropanol system. The different shapes of CuO nanocrystals can be obtained simply by adjusting the amount of adding water in the reaction system. Rod-like CuO nanocrystals with diameters of 5 nm and lengths of 20 nm, and spherical CuO nanoparticles with sizes of 5-8 nm can be formed. Furthermore, the obtained CuO product has a high surface area of 128 m2/g, which is very important for its applications especially in catalysts.
