Abstract
Carbon microspheres were prepared from waste cotton fibers by
hydrothermal carbonization (HTC) with the addition of copper sulphate in this
work. The important influence factors, temperature, concentration of copper
sulphate, resident time were explored here. The smooth and regular carbon
microspheres could be formed at 330°C with 0.15 wt% copper sulphate after 6 h
from waste cotton fibers. The crystal structures of cotton fibers were destructed in a
short resident time with 0.15 wt% copper sulphate from SEM images and XRD
patterns of solid products. This strategy provides a new, mild and efficient method
to prepare carbon microspheres from waste cotton fibers by HTC. FTIR spectra
verified that the abundant functional groups existed on the surface of synthesized
carbon microspheres. From XPS and element analysis results, the copper sulphate
participated in the forming process of carbon microspheres indeed. The presence of
copper sulphate in the carbon microspheres provided a possibility for the
application in antibacterial field. Besides, the catalytic mechanism of copper
sulphate on the hydrolysis and carbonization of waste cotton fibers were also
discussed. In conclusion, the copper sulphate is an efficient agent for preparing
carbon microspheres by HTC from waste cotton fibers.
