In this current research work, the sol-gel method was employed to synthesise, characterize and evaluate photocatalytic activity of bismuth ferrite (BiFeO3, BFO) doped with two distinctive components consisting a rare earth element Gadolinium (Gd) transition metal Copper (Cu). The dopant concentrations were systematically varied different weight percentages (wt.%) denoted as Bi1-xGdxFe1-yCuyO3 (where ‘x’ = 0.10, 0.15 0.20 wt.%, where ‘y’ 0.05, wt.%). Subsequently, characterizations prepared samples conducted using an array cutting-edge analytical techniques including X-ray diffraction (XRD), filed emission scanning electron microscopy (FE-SEM), energy dispersive analysis (EDAX), transmission (TEM). XRD results indicated that presence small impurity peaks found in both Gd-doped BFO GdCu-doped BFO. FE-SEM TEM provided confirmation material observed spherical shape, elemental compositions also confirmed through EDAX analysis. degradation Rhodamine B dye under influence visible light irradiation carried out revealed varying times, specifically, for Gd Cu-doped (Gd Cu 0.1 wt.%) achieved almost 98% occurred 30 minutes.
