Hemin, a protoporphyrin IX with a similar peroxidase-like activity as peroxidase enzyme, is the active center of heme-protein which includes cytochromes, peroxidase, myoglobin and hemoglobin. With the excellent catalytic ability to H2O2 through the reversible transformation of Fe (II) to Fe (III),...

However, fine size particles create problems associated with recovery from the treated water. Therefore, it is highly desirable...
The comparative tests on MO discoloration in different systems revealed that Fe3O4/maifanite composite exhibited much higher Fenton-like catalytic activity than Fe3O4NPs and the heterogeneous Fentonlike reaction governed the discoloration of MO. Kinetic results clearly showed that MO discoloration ...
(Fig.3a). The catalytic activity of FeN4−C significantly enhanced after introducing isolated Fe−N4sites and the observed rate constants (kobs) increased by 4.2-fold compared with referential NC (Fig.3b). The poisoning tests conducted by potassium thiocyanate (KSCN) further support that Fe...
catalytic activity of PdO/CeO2 was tested in the heterogeneous Fenton‐like degra‐ dation of acid orange 7 (AO7) and salicylic acid (SA), both in the dark and under visible irradiation. Deposition of PdO accelerates the Fenton‐like degradation of SA, which reaches a maximum at 1.0 atom...
In recent years, it has been discovered that BiFeO3 exhibits Fenton-like catalytic activity, effectively catalyzing the generation of hydroxyl radicals (•OH), a strong oxidizing species, from H2O2 under non-illuminated conditions [21]. Further investigations into the mechanism of Fenton-like ...
