Abstract
The effects of copper nanoparticles (CuNP) dispersion on the optical and electrical properties of mesoporous SBA-15 like silica were investigated. Full characterization of the resulting SBA-15-Cu through X-ray diffraction (XRD), thermogravimetry analysis (TGA), scanning electron microscopy (SEM), energy dispersion X-ray fluorescence (ED-XRF), diffuse reflectance (DRS) and Fourier Transform Infrared spectroscopy (FT-IR) revealed marked changes in the structure properties after copper incorporation. Slight decrease in the optical band gap energy in the SBA-15-Cu was also noticed. The shifts towards higher wavelengths are attributed to change in the acceptor capacity level induced by iron nanoparticles. Measurements of Z' and Z" in temperature showed an improvement in proton mobility of SBA-15-Cu. Deeper insights in the capacitance and conductance by impedance spectroscopy measurements over a wide range of frequencies at various temperatures suggest that CuNPs interaction with SBA-15 surface and silanol deprotonation can be, at least partly, responsible for conductance improvement. The above properties make these materials to be regarded as efficient materials for potential applications in electronics.
