In class of TMDs, MoS 2 is comprehensively explored as a co-catalyst due to the extraordinary activity for photocatalytic activity of organic dye degradation. But the catalytic activities of MoS 2 are generated through S ions on depiction edges. Also numerous of S ions existed on basal planes are catalytically inactive. The insertion of external metals in MoS 2 organism is extensive way for activation of basal planes surface to enhance concentration of catalytically active sites. For this purpose, nanoparticles of Nickel (Ni) doped MoS 2 are prepared by hydrothermal technique. Structural and morphological analysis are characterized by XRD and SEM, respectively. XRD results showed that Ni is completely doped into MoS 2. SEM showed that pure MoS 2 has sheet like structure and Ni doped MoS 2 has mix disc and flower like structure. Band gap energy was observed in declining range of 2.30-1.76 eV. The photocatalytic activity of pure MoS 2 and Ni doped MoS 2 were evaluated by degrading MB and RhB dyes under UV light irradiation. MB dye degradation of MB was 71% for pure MoS 2. For 1% to 5% Ni doping in MoS 2 , MB dye degradated from 85% to 96%. It means that MB dye degradation of MB was enhanced continuously by increasing the concentration of Ni doping. RhB dye degradation of RhB was 62% for pure MoS 2. For 1% to 5% Ni doping in MoS 2 , the RhB dye degradated from 77% to 91%.
