Abstract
The nanocrystalline CuO powders with different microstructure were prepared by precipitation method using Cu (NO3)2 as copper raw material, water or ethanol as dispersants, and NaOH or NaOH-Na 2CO3 as precipitates. The structure, particle size and morphology of resulting CuO powders were characterized by XRD and TEM. Results indicated that the microstructure of resulting CuO powders depends on calcining temperature, dispersants and precipitates. TEM photographs reveal that the CuO particles produced using water as dispersant are ellipsoids with good dispersity, while the CuO particles produced using ethanol as dispersant are spherical shape with better dispersity. Compared with NaOH as precipitate, the CuO particles produced using NaOH-Na2CO3 as precipitate are smaller, but more heavily agglomerated. In addition, the catalysis of the nanocrystalline CuO powders on NH4ClO4 is investigated.
