and •OH is generated at the same time. So the regeneration of Fe
3+ /Fe
2+ cycles
would make more strong oxidant •OH for the photocatalytic degradation.
15.4 Conclusions
In summary, we have briefly introduced the Fenton technology and specifically
clarified the mechanism of Fenton process. Besides that, the application of transition
metal dichalcogenides (such as MoS 2 ) in transistor, hydrogen evolution reaction
(HER), and heterogeneous Photo-Fenton process is also introduced. As a unique
representative of transition metal dichalcogenides, MoS 2 has been widely explored
as a cocatalyst for photodegradation of contaminants. MoS 2 has a broad promising
future in Fenton technology.
