The transparent amorphous carbon thin films
(ACTF) were prepared through a batch acid spraying technique in the presence of cobalt silicate as a catalyst at low
temperature between 30 and 45 ◦C. Hence, the catalyst was
prepared using silica gel as a basic matrix and supporting material to produce ACTF. The produced active carbon
was characterized using XRD, FTIR, and Raman spectrum.
The high-resolution transmission electron microscope (HRTEM) and thermogravimetric analysis were used to analyze
the surface morphology and thermal stability of cellulose
and ACTF, whereas the surface area was calculated using
the standard iodine method. The results of Raman spectroscopy and TEM show the realization of ACTF suspension
with highest constitutional order and the lowest number of
layers with confirming of the succeed preparation of thin
ACTF layers in thickness and average size of 1 and 100mm,
respectively.In addition, under these conditions, the activated
carbons’ iodine value is 721.64 mg/g, and the yield ratio is
85.71% |
