Mesoporous nanocomposite aerogel of Au-TiO2 benefits from unique morphological properties of aerogels, intrinsic physical and chemical properties of TiO2 and plasmonic effects of Au nanoparticles is considered to be used as SERS substrate. In this research the Au-TiO2 nanocomposite aerogel was prepared by synthesizing titania gel and loading it with Au nanoparticles and then supercritical drying of composite gel with CO2. The performance of this material for being used as SERS substrate was established by using crystal violate (CV) as test molecule. The lowest concentration of CV detectable by this substrate was 10-9 M
Keywords: Titania aerogel, noble matal, plasmonics, nanocomposites, SERS.
