CRYSTALLIZATION AND CHARACTERIZATION OF CHROMIUM-CONTAINING SILICALITE-1
ABSTRACT: Chromium-containing
silicalite-1, designed CrS-1, was synthesized by the hydrothermal method and characterized
by XRD and FTIR techniques. The objectives of the research are to study the
synthesis of CrS-1 and investigate the effect of crystallization temperatures
and times toward its character. All samples of CrS-1 crystallized in
orthorhombic structure and Pnma space group. The phase observed in the XRD patterns
of CrS-1 synthesized from 150 to 190oC for 11 days showed only
MFI-type phase. The CrS-1 prepared under static condition for 1 day at 150 o C
indicated -SiO 2 phase, on the contrary, the
samples conditioned for 2 to 8 days at 150oC are only MFI
phase.
