Abstract

In the present work, LaMnO3/Fe3O4 nanocomposites with different molar ratios (1:1, 1:0.5, 1:0.3, 1:0.1, and 1:0.05) have been successfully synthesized using the co-precipitation method. The prepared nanocomposites were characterized using X-ray Diffraction (XRD) and Vibrating Sample Magnetometer (VSM). The photocatalytic activity was evaluated using visible light irradiation. Methylene blue (MB) was used as a model of organic pollutant. The obtained nanocomposites exhibited much higher photocatalytic activity and stability than pure LaMnO3 under visible light irradiation. The result showed that LaMnO3/Fe3O4 with the molar ratio of 1:0.5 showed superior photocatalytic activity than others. The active species on photocatalytic activity was investigated by measuring the photocatalytic degradation in the presence of scavenger.
