Highly active nanostructured silver tungstate for visible-light-driven photocatalysis is fabricated via an effortless and quick sonochemical pathway. Role of capping agent kind, concentration of tungsten source and time of sonication as efficacious variables has been explored for fabrication of silver tungstate through sonochemical pathway. The outcomes denoted successful fabrication of homogeneous silver tungstate nanoparticles with fine size in optimal circumstance (30 min of sonication, usage of SDBS and 0.01 mol of tungsten source). As-fabricated photocatalyst, the nanostructured silver tungstate has been identified with the aid of multiple techniques. The created silver tungstate micro/nanostructures employed to degrade diverse contaminants beneath visible light. Degradation yield of 94.23% for Acid red 14 and 96.31% for eriochrome cyanine R and 100% for Rhodamine B has been obtained with the help of the nanostructured silver tungstate (created in optimal circumstance) within 60 min. Further, nanostructured silver tungstate could completely destruct 2-naphthol within 15 min. No considerable decrement in performance was seeable within re-utilized experiments. The easy, effortless and quick fabrication of highly active nanostructured silver tungstate for visible-light-driven photocatalysis through sonochemical pathway may contribute efficient in environmental remediation.
