| dc.description.abstract | Synthesis of silica material from oil palm shells as a source of silica and
glycerol as a template has been carried out. Silica was extracted by the alkaline
method using NaOH solution. Silica powder obtained is white by adding a template
in the form of glycerol with variations in weight of 2 g, 4 g, 6 g. A mixture of silica
and glycerol was calcined at 600°C for 3 hours and then characterized by FT-IR,
XRD and BET analysis. The FT-IR spectrum of silica from oil palm shells shows the
presence of Si-OH and Si-O-Si groups. The results of the XRD analysis have widened
diffraction peaks which indicate that the silica material is amorphous. BET analysis
results of palm shell silica showed pore size, pore volume and surface area of 10.21
nm, 1.168 cc/g and 18.617 m2/g, respectively. Preparation of silica material with
variations in the weight of the glycerol template, namely 2 g, 4 g, and 6 g. The BET
analysis results showed that the surface area was 20.043 m2/g, 29.274 m2/g, 34.695
m2/g, the pore volume was 0.0695 cc/g, 0.1144 cc/g, 0.0714 cc/g, respectively. and
pore sizes of 6.68 nm, 7.81 nm, 4.12 nm respectively which belong to the mesoporous
size. | en_US |
