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… More >
