The doped bismuth ferrites have got tremendous attraction owing to its ideal properties for photocatalysis application. We have fabricated the novel lanthanum and manganese co-doped BiFeO3 (namely BLFMO)/graphene nanoplatelets (GNPs) nanohybrid for photocatalysis with easy and effective synthesis routes namely the co-precipitation (C-hybrid) and hydrothermal (H-hybrid) processes. The H-hybrid showed crystalline structure with lower band-gap than the C-hybrid samples. However, C-hybrid showed higher dye degradation (92%) due its higher surface area (55 m2/g) and the fine incorporation of BLFMO nanoparticles into the GNPs which enhanced the surface adsorption. This is verified from more degradation in dark conditions for these samples. The proposed nanohybrids are novel for photocatalytic application fabricated through the low cost routes which show higher efficiency for practical applications.
