Solar light driven enhanced photocatalytic efficiency of Graphene based composite of co-doped Bismuth Ferrite (Ba0.5 Bi0.5 Nd0.5 Fe1.5 O3/Gr0.375) for Crystal Violet and Paracetamol

Different dyes and drugs used in industries when released without any treatment in water bodies cause water pollution. There is a need of synthesizing cost-effective and efficient photocatalyst for their degradation. Herein, Ba and Nd co-doped bismuth ferrite BFO (Ba_0.5 Bi_0.5 Nd_0.5 Fe_1.5 O₃) and BFO@G (Ba_0.5 Bi_0.5 Nd_0.5 Fe_1.5 O₃/Gr_0.375) were successfully fabricated. X-ray Diffraction and Fourier Transform Infrared Spectroscopy were performed to confirm the synthesis of samples. Electrochemical measurements were carried out to further evaluate the characteristics of fabricated catalysts and R_ct values of 3.90 Ω and 2.06 Ω were observed for BFO and BFO@G. BFO@G showed 72.72 % degradation of CV and 80.26 % of PC. The composite material showed enhanced performance due to the integration of graphene which provide additional conductive pathways and reduces the rate of electron-hole pair recombination. This research contributes valuable insights into the development of efficient photocatalytic materials for environmental applications.
