Deposition of gold nanoparticles on titanium nanopits

Abstract

A necessity to obtain a new matrix for metal nanoparticles or quantum dots require to develop materials, which dimension could be easily controlled. The TiO2 nanotubes obtained via anodic oxidation of a titanium foil could be easily produced and their synthesis conditions as electrolyte composition, applied voltage, time of anodization directly influence on their dimension (Kobylański et al., 2018). Utilizing the surface of titanium created after removing of the NTs allow to obtain pits, which could be a space for deposited nanoparticles. Subsequently, it is possible to deposit the gold nanoparticles from their precursor by photodeposition or spin-coating method and finally, obtain the titanium matrix with the nanoparticles. The shape of gold nanoparticles depends on the experiment condition, but it is possible to obtain the triangle structures of gold (Carville, Neumayer, Manzo, Gallo, & Rodriguez, 2016; Ng, Razak, Aziz, & Cheong, 2014).
