which replaced the toxic acids and amines to avoid polluting the environment.
Besides, Sargassum thunbergii is so abundant across the coast of China that the
photocatalyst can be mass prepared with low cost. This method can be regarded as
the exploration on green synthetic technology and has potential of further research.
The synthesized material displayed excellent catalytic performance, showing 96%
degradation rate under mild conditions. Except the methods mentioned above, there
are several other ideas such as hydrothermal method and co-participation method,
etc., which facilitate the wide application of rGO–Fe 3 O 4 as photocatalyst.
10.2.3 Graphene/Other Iron (Hydr)oxide Composite
as Photocatalyst in Fenton Reaction
In addition to the above composites, other iron (hydr)oxides have also been incorporated with graphene to prepare highly effective photocatalysts for Photo-Fenton
reaction. For instance, ZnFe 2 O 4 [69], MnFe 2 O 4 [70], and CoFe 2 O 4 [71] with spinel
structure have attracted much attention for their visible light-driven photoactivity.
