Abstract

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.

基于石墨烯的共掺杂铋铁氧体（Ba0.5 Bi0.5 Nd0.5 Fe1.5 O3/Gr0.375）复合材料在太阳光驱动下增强对水晶紫和扑热息痛的光催化效率

工业中使用的各种染料和药物在未经任何处理的情况下排放到水体中会造成水污染。因此，需要合成具有成本效益的高效光催化剂来降解它们。在此，我们成功制备了钡和钕共掺杂的铋铁氧体 BFO（Ba0.5 Bi0.5 Nd0.5 Fe1.5 O3）和 BFO@G（Ba0.5 Bi0.5 Nd0.5 Fe1.5 O3/Gr0.375）。为确认样品的合成，进行了 X 射线衍射和傅立叶变换红外光谱分析。BFO@G 对 CV 和 PC 的降解率分别为 72.72% 和 80.26%。石墨烯为复合材料提供了额外的导电途径，并降低了电子-空穴对重组的速率，从而提高了复合材料的性能。这项研究为开发用于环境应用的高效光催化材料提供了宝贵的见解。

期刊介绍： Current Applied Physics (Curr. Appl. Phys.) is a monthly published international journal covering all the fields of applied science investigating the physics of the advanced materials for future applications. Other areas covered: Experimental and theoretical aspects of advanced materials and devices dealing with synthesis or structural chemistry, physical and electronic properties, photonics, engineering applications, and uniquely pertinent measurement or analytical techniques. Current Applied Physics, published since 2001, covers physics, chemistry and materials science, including bio-materials, with their engineering aspects. It is a truly interdisciplinary journal opening a forum for scientists of all related fields, a unique point of the journal discriminating it from other worldwide and/or Pacific Rim applied physics journals. Regular research papers, letters and review articles with contents meeting the scope of the journal will be considered for publication after peer review. The Journal is owned by the Korean Physical Society.
