Abstract

Mn2+ doped ZnFe2O4 nanocrystals have been successfully synthesized by one-pot autocombustion method. The synthesized MnxZn1-xFe2O4 nanocrystals were characterized by XRD, FT-IR, HR-SEM, TEM, EDX, BET, DRS, PL, and VSM. The results indicated that the prepared spinel MnxZn1-xFe2O4 nanocrystals showed high crystallinity and uniform size distribution with particle-like morphologies. The present study leads to enhance the photocatalytic activity of MnxZn1-xFe2O4 with the addition of TiO2. Having established that spinel MnxZn1-xFe2O4 was photocatalytically active, the mixed oxide catalysts of MnxZn1-xFe2O4 -TiO2 were also tested for the photocatalytic degradation of 4-chlorophenol.
