Magnetic C@Fe3O4 microparticles was synthesized with magnetite (Fe3O4) as the
magnetic core and carbon nanotubes (CNTs) as carbon source via hydrothermal
method and applied as photocatalyst in degradation of methyl orange (MO). The
synthesized C@Fe3O4 is characterize with FTIR, SEM, TGA, XRD and BET. The results
show the peak which indicate the presence of bonding between Fe-O and the size of
the C@Fe3O4 is within 90–433 nm. The prepared C@Fe3O4 which synthesized with
three different mass of CNTs have amorphous carbon diffraction peak and all the
characteristic peaks of Fe3O4. The C@Fe3O4 which synthesized with 0.5g CNTs which
has BET surface area of 129.61 m²/g shows the highest degradation percentage of
MO which is 83%.
