Nano-copper oxide was prepared by utilizing photolysis method and characteristic by using FT-IR, XRD and SEM; the nano size was about 51 nm, environmental impact (pollution reduction) can be improved by using nanostructure particles in preventing corrosion, and nanocomposites have also proven to be an effective alternative to other hazardous and toxic compounds. The results of the current article indicated that the inhibition efficiency increases with increasing concentration of nano-oxide which is added to methyl orange, curcumin, the corrosion rate (CR), inhibition effectiveness were studied at different temperatures. The results showed an increase corrosion rate and a decrease in inhibition efficiency with increase temperature.
