Abstract

A 6x6 matrix of anodization experiments was planned and designed to obtain a tubular matrix of TiO2 where we can observe and identify exactly how the morphology is influenced by voltage and time under an organic electrolyte and using graphite as cathode, even identify the time-lapse where nanograss is introducing in our nanotubular matrix. The anodization process consisted of an organic electrolyte of ethylene glycol, deionized water and NH4F, six different voltages and a time lapse from 1 to 6 hours. After the anodization, the whole set of anodized samples were rinsed with deionized (DI) water and dried under heat gun (low temperature), no samples were cleaned in ultrasonic bath because we wanted to preserve the nanograss structure if it was there. The anodized samples were annealed to obtain the crystalline anatase phase. Optical characterization was performed by Raman spectroscopy to identify the increases in signal intensity, associated with the presence of nanotubes or nanograss. The morphological characterization was performed with scanning electron microscopy to visually verify the presence and density of the nanotubes, morphological structure (radial and length dimensions) and if nanograss was in there.
