Enhanced Photocatalytic Degradation Activity of BiFeO3 Microspheres by Decoration with g-C3N4 Nanoparticles

In this work, the g-C3N4 nanoparticles decorated BiFeO3 microspheres composites (g-C3N4/BiFeO3) were successfully synthesized by hydrothermal treatment of g-C3N4 nanoparticles together with BiFeO3 microspheres. The SEM and HRTEM observation indicate that the C3N4 nanoparticles with size of 30-50 nm are well decorated on the surface of BiFeO3 microspheres. The photocatalytic activities of the samples are investigated by the degradation of methylene blue (MB) under the irradiation of simulated sunlight. The as-prepared g-C3N4/BiFeO3 composites exhibit remarkable enhanced photocatalytic activity ...
