---

ABSTRACT
TiO2 is the most widely used material in the photocatalysis process, one of which
is to degrade phenol waste. To increase the adsorption ability and photocatalyst
compatibility, TiO2 was added with carbon-based materials namely graphene and
cocoPAS surfactant which help to disperse graphene. The addition of Fe3O4
magnetic material is also expected to facilitate the separation of the catalyst by
using an external magnet. The purposes of this research are to synthesize and
characterizing graphene/TiO2/Fe3O4 composite and to obtain
graphene/TiO2/Fe3O4 composite for separation of phenol photodegradation
results. This research started with the modification of graphene with cocoPAS
surfactant, synthesis of Fe3O4, synthesis of graphene/TiO2/Fe3O4 composite with
various amount of Fe3O4 in composite (0.3, 0.5 and 0.7 grams), performance test
of the composite using phenol, and magnetic separation test. Composite were
characterized using SEM, XRD, FTIR, BET analysis and UV-Vis
spectrophotometer. SEM analysis results show the composite morphology. The
surface area of graphene/TiO2/Fe3O4 composite is 38 m2/g with the average size
of TiO2 anatase, rutile, and magnetite crystals are 22.49, 25.9 and 22.4 nm
respectively. Anatase and rutile fractions obtained were 85% and 15%. In the
composite, there are O-H, Fe-O, Ti-O-Ti, Ti-O-C, and C-C bonds at 3185 cm-1,
615 cm-1, 510.44 cm-1, 1557 cm-1, and 1651 cm-1 respectively, which show the
composite constituent bonds. Degradation percentage of graphene/TiO2/Fe3O4
composite with mass variations of Fe3O4 in composites 0.3, 0.5, and 0.7 grams
respectively are 45.3%, 43.3% and 36.2% with the magnetic separation test for
60, 45 dan 23 minutes. The higher the mass of Fe3O4 in graphene/TiO2/Fe3O4
composites, the faster the separation time needed, but the composites performance
to degrade phenol is decreased.
Keywords: Photocatalytic, magnetic composite, cocoPAS, photodegradation,
phenol.
