Why is it important?

A novel composite of Fe0.01Ni0.01Zn0.98O nanoparticles (FNZPs) and conducting polymer polyaniline (PANI) was synthesized by in situ free radical polymerisation method. Iron/nickel co-doped zinc oxide nanoparticles (NPs) were synthesized by sol–gel technique. The NPs and Fe0.01Ni0.01Zn0.98O/polyaniline nanocomposites (FNZP/PANI) were characterized by FTIR, EDX, SEM, HRTEM, SAED, UV–Vis and XRD techniques. Optical and photocatalytic studies revealed that formation of composite further lowers the optical band gap of FNZPs, leading to enhanced visible light absorption. Admirable photodegradation efficiency against methylene blue dye (MB) was achieved for composites. The electrical conductivity was also enhanced. The antibacterial activity of the synthesized NPs and nanocomposites (NCs) against Escherichia coli (E. coli) bacteria was analyzed by optical density method
