چکیده

In this current research work, the synthesis of copper (cu) doped and magnesium (mg) co-doped of befio3 (bfo), i.e bife1-xcuxo3 (where; x= 0.1, 0.15 and 0.2 wt.%) and bi1-ymgyfe1-xcuxo3 (where; y=0.05, 0.1 and 0.15 wt.%) were prepared by sol-gel method. the obtained samples were analyzed by various characterization techniques including x-ray diffraction (xrd), surface morphology examined by field emission scanning electron microscopy (fe-sem), and transition electron microscopy (tem). it was noted that cu (0.15 wt.%) doped bfo had notable photocatalytic activity for rhodamine (rhb) dye degradation when exposed to visible light irradiation. in addition to cu (0.15 wt.%) by adding mg (0.1 wt.% ) as a co-doping, exhibited higher photodegradation than the pure bfo, cu-doped bfo (0.1and 0.2 wt.%) and mg co-doped bfo (0.05 and 0.15 wt.%). here we reported a new driven photocatalyst by doping of cu and co-doping of mg into bfo simultaneously. these played a key role in hampering the recombination of electron-hole pairs hence the chance to increase dye degradation performance. these findings could be useful for developing affordable photocatalysts for wastewater purification.
