Karakterisasi Katalis TiO2 dan TiO2/Karbon Aktif yang Diimobilisasikan Pada Pelat Titanium
ABSTRACT: Study of TiO2 and
TiO2 active carbon photocatalyst was done. Immobilization was carried out by
sol-gel process using titanium diisopropokside bis-acetylacetonato as titanium
precursor. The catalyst was characterized using XRD and SEM. The activity of
catalyst was tested using 10 ppm of pentachlorophenol (PCP) as a model of
organic waste. The test was done by irradiating PCP solution using UV lamp and
varying the catalysts of TiO2, and TiO2/C of 8/2 and 5/5. About 5 mL of sample
was taken out at interval time of 1, 2, 4, 6, 8 and 10 h iradiation followed by
the measurement of PCP residue and chloride ions. From the characterization
results it is known that calcined TiO2 andTiO2/C of 8/2 and 5/5 have anatase
structure and active as a catalyst. The activity results using PCP as an
organic waste showed that combination of TiO2 and active carbon would increase
the activity of the catalyst, but at high percentage of active carbon the
performance of the photocatalyst decreased.
