Abstract
Herein, in this report, was developed a nano-hybrid of Fe3O4/Ag/GO nanoparticles (NPs), constituted of graphene oxide (GO) supporting flower-like Fe3O4/Ag NPs in the presence of citric acid surfactant. The citric acid-functionalized Fe3O4/Ag/GO nanoparticles were used for Horseradish peroxidase (HRP) immobilization. The immobilized HRP can be tested to remove 2, 4-dichlorophenols in the presence of H2O2, the degradation of 2, 4-DCP at pH 6 at 25°C and in the presence of H2O2 (0.8 mM) was for free and immobilized HRP of 40 % and 77 %, respectively. Moreover, immobilized HRP showed a high removal efficiency of ∼94% in the presence of 0.6 mM of H2O2,.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
