The Mn-doped MoS2 (Mn-MoS2) material is fabricated by a facile one-step calcination method. The Mn2+ content introduced into MoS2 is ranged from 1 wt% to 7 wt%. The X-ray diffraction (XRD) and scanning electron microscopy SEM results suggest that the doping of Mn2+ does not alter the crystal structure and the morphology of MoS2. However, it helps the Mn-doped MoS2 to exhibit stronger visible light absorption and higher magnetism. Especially, in the RhB degradation under visible light irradiation, better photocatalytic performance of the as-prepared Mn-doped MoS2 is observed compared to that of pure MoS2.
