In this study, near field effect of plasmonic nanoparticles on the photocatalytic performance of TiO2 nanotubes in range of sunlight, have been studied. TiO2 nanotubes have been synthesized by using anodization. In order to improve photocatalytic properties of TiO2 nanotubes, the gold nanoparticles have been coating with two different method (spin coating and deposition precipitation) on TiO2 nanotubes. Photo catalyst behavior of samples, represent 44% increasing in photocatalytic activity of TiO2 nanotubes in spin coating method of gold nanoparticles, and 143% increasing in deposition precipitation method. Photocatalytic activity increased significantly in the second method, mainly due to the influence of gold nanoparticles into TiO2 nanotubes that causes a greater volume of nanotubes are influenced by increasing the near filed by gold nanoparticles. But in the case of spin coating, gold nanoparticles are just one layer on the top of the nanotubes and they have little influence. So in this case, plasmonic upgrade occure for less volume of TiO2 nanotubes.
