Photodegradation of Methylcyclohexane in Two Phases with Modified-titania Immobilized on Pumice

Slamet Slamet, Oktrianto Oktrianto, Agung Hendarsa, Ratnawati Ratnawati, Salim Mustofa


Abstract: The photocatalytic
degradation of methylcyclohexane (MCH) in two phases (aqueous and vapor) was
examined using modified titania that was immobilized on pumice and performed in
the system of a specific condition. The photodegradation system that
used a particular
configuration reactor and modified catalyst could facilitate the two-phase photodegradation of MCH simultaneously. The photocatalyst
was prepared by the mechanical mixing of urea and TiO2 P25 with mass
ratios of 1:3 and 2:3, respectively and then calcined at 350 and 450oC. This modified photocatalyst was then immobilized on
pumice and finally used for the
photodegradation of MCH. The
Infrared spectra studies revealed that modified titania with urea successfully
incorporated a
non-metal dopant within the TiO2 lattice. The catalyst that spread evenly across the surface of the pumice can
be seen from Scanning Electron Microscope (SEM) characterization. The loading of 7.5% mass photocatalyst that immobilized on pumice
degraded MCH in two-phases
simultaneously during a 120 minute period and can be considered the optimum
