Zusammenfassung:	Photocatalysis is one of the versatile processes widely applied for the treatment of environmental water pollutant. In this work, NiS/Ag2MoO4 heterostructured nanocomposite (NCs) was synthesized via ultra-sonication assisted and chemical co-precipitation methods. The prepared particle was characterized using HR-TEM, SAED, EDAX, UV–vis DRS, XRD, nitrogen adsorption and desorption, PL, and XPS. The band gap of NCs was found to be 2.77 eV which facilitates the enhanced activity in visible region. The heterostructure formation between NiS and Ag2MoO4 have induced the separation of charges efficiently which caused the increase in photocatalytic performanc. The photocatalytic study reveals that NiS/Ag2MoO4 enhanced the degradation of MB (90.8%) relative to individual NiS and Ag2MoO4. The MB degradation followed pseudo first order reaction (R2
