Abstract
The well-known high pressure high temperature (HPHT) method has been used for preparing diamond since 1986. This research introduces a new method for preparing diamond by using the global Hummer method after changing two main agents, namely, the frequency of ultrasound waves and the exposure time of these waves. The frequency was increased to 40 kHz, while the exposure time was increased to 2 h. It was found that applying the Hummer method on graphene oxide with an ultrasound exposure time of 20 min and 2 h can result in graphene oxide and nanodiamond (ND), respectively. The resulting ND began to grow after it was left for 10 days. The spectral properties of the diamond were characterized by using Ultraviolet-visible (UV-Vis) and Raman. The UV-Vis showed that the absorption peak at 220 nm is within the ultraviolet region, while the bandgap was found to be 5.6. The Raman confirmed the presence of the functional group for the diamond at 1332 cm−1 wavenumber. Moreover, the morphology property of the diamond and stages of diamond formation have been visualized by using scanning electron microscope (SEM) and optical microscope.
