摘要：In the present investigation, silver decorated and bismuth doped α‐Fe2O3 (Ag/Bi‐Fe2O3) was successfully synthesized using the co‐precipitation method. The size, shape, surface area, and magnetic properties were characterized by XRD, FE‐SEM, EDX, BET, VSM, and UV‐Vis‐DRS techniques. The synthesized nanoparticles were used as a photocatalyst for the degradation of rose bengal (RB) dye under simulated solar light irradiation. Ag/Bi‐Fe2O3 showed the better photocatalytic activity of 97.11 % within 135 min when compared to Bi‐Fe2O3 and Ag‐Fe2O3. The superior photo‐catalytic activity of Ag/Bi‐Fe2O3 was mainly ascribed to visible light absorption and the suppression of photo‐generated electron‐hole recombination. Ag/Bi‐Fe2O3 was found to be a stable photocatalyst during recycling experiments. Besides, the magnetic property of Ag/Bi‐Fe2O3 makes it an ideal candidate for separation and recovery during recycling.The schematic diagram of electron‐hole transfer process in Ag/Bi‐Fe2O3 under simulated solar light irradiation.
