PEMBUATAN DAN KARAKTERISASI KATALIS ZnO/KARBON AKTIF DENGAN METODE SOLID STATE DAN UJI AKTIFITAS KATALITIKNYA PADA DEGRADASI RHODAMIN B
ABSTRACT: Composite catalyst
ZnO/Activated Carbon (ZnO/AC)
had been synthesized
successfully by solid state
method. Synthesis was
done by varying
the addition of
activated carbon (AC)
2%, 5%, and 10%
ZnO mass. Composite
catalyst were calcinated
at 400oC and
characterized by FTIR (Fourier
Transform Infra Red),
XRD (X-Ray Diffraction),
SEM (Scanning Electron Microscopy). Based
on the results
of FTIR, absorption
appeared in the
region wave number 1400-1600 cm-1,
which indicated stretching
of C=C was
assumed come from
AC. From the XRD results, it was known by the addition
of AC, not overly change the crystallinity and crystal size of
ZnO, the crystal
structure is hexagonal
(wurtzite). SEM images
showed AC prevented the
agglomeration of ZnO
that would expand
the surface area
of ZnO and
increased catalytic activity of
ZnO. For the results of the catalytic activity test, catalyst ZnO/AC was tested
on the degradation of Rhodamine
B solution (10
ppm) by UV
light irradiation, where
the increasing number of trains
the catalytic ability of ZnO also increased, it could be concluded that
activated carbon can support to increase the role of ZnO in degrading Rhodamine
B.
