Abstract:
Sonochemical reduction of copper nitrate, using 20 kHz ultrasound in aqueous solutions in the presence of urea, led to the formation of layered copper hydroxy nitrate nanosheets, as evidenced by scanning and transmission electron microscopy images. Fourier-transform infrared, X-ray diffraction, and X-ray photoelectron spectroscopy analyses were used to characterize layered Cu2(OH)3NO3 nanosheets. The ultrasound-assisted progressive hydrolysis of urea and in situ formation of Cu(0) through the sonochemical reduction process induced homogeneous nucleation and crystallization of layered Cu2(OH)3NO3 nanosheets.
