The purpose of this research is preparation of titanium dioxide nanotubes modified with nickel nanoparticles as a photocatalyst sensitive to visible light. For this purpose, at first, titanium dioxide nanotubes was synthesized on the surface of titanium using electrochemical anodizing; then by immersion of prepared nanotubes in an aqueous solution of nickel nitrate, film of nickel nanoparticles on the surface of the nanotubes were produced. Morphology and crystal structure of the resulting films were studied using scanning electron microscopy and X-ray diffraction. To determine the composition and confirmation the presence of nickel nanoparticles, we used from energy dispersive X-ray spectroscopy (EDX). Then, photocatalysts efficiency of obtained nano-catalysts for the removal of methylene blue dye was performed. Photocatalytic test results showed that produced nanocatalysts have good activity.
