Photocatalytic degradation of Rhodamine B dye under visible light using Cerium-Cobalt CO-doped bismuth ferrite nanoparticles

The present study designates the photocatalytic degradation efficiency of RhB dye using cerium-cobalt co-doped BiFeO3 nanoparticles. Nanoparticles of Ce0.1CoxBi1-xFe2O3 (0 ≤ x ≤ 0.2) have been facilely synthesized via sol-gel auto-combustion method. FESEM analysis revealed the irregular-shaped nanop...
