[Display omitted] •Fabrication of a heterostructure composite NiO-Fe2O3-RGO (NFR) by hydrothermal.•Collected dye solution at Handloom wastage in Andhra Pradesh.•NFR composite as photocatalyst for the degradation of handloom dye under visible light irradiations.•Antibacterial studies were conducted and showed effective results on E. Coli and S. aureus. Herein, we report that the fabrication of RGO based bimetal oxides, NFR (NiO-Fe2O3-RGO) composite can be used for degradation of industrial dye pollutants. In brief, the NFR ternary composite was achieved by hydrothermal route which is widely used nowadays for the preparation of nanomaterials. The prepared material was allowed to study in a detail for its optic, electric and spectroscopic properties using sophisticated analytical devices. The analysis results confirmed the pure phase of prepared NFR composite via hydrothermal route. Moreover, prepared NFR composite was examined for its photocatalytic efficacy over the degradation of handloom dye which is collected at Handloom wastage in Andhra Pradesh. The results were compared with other blend materials and found to be prepared NFR-10% composite was most effective as good photocatalyst for the degradation of handloom dye under visible light irradiations. The prepared NFR composites were studied and found that NFR-10% composite was the most effective photocatalyst for the degradation of solution dominantly 335 nm (80%) than 274 nm (71%) and 219 nm (22%). Antibacterial studies were conducted and showed effective results on E. coli and S. aureus. The analysis results stated that E. coli was the most effective by NFR-10% composite (16 mm) as well as S. aureus by NFR-5% composite (16 mm) at higher dilution. Put together we summarise that the prepared composites in this study were effective for the decontamination of handloom dye and pathogens from waste water.
