Facile Synthesis of Mn doped Bi2S3 Photocatalyst for Efficient Degradation of Organic Dye under Visible-Light Irradiation

•Mn doped Bi2S3 photocatalyst was prepared using hydrothermal method with different doping concentration of Mn 1%, 2%, 3% and 4%.•Physicochemical characterization of Mn doped Bi2S3 nanoflower were carried out•The photodegradation rate of 3% Mn-Bi2S3 is faster for Rhodamine B dye.•The photodegradation mechanism is also discussed in detail.
