摘要: We present a novel and straightforward approach to fabricate large-scale robust free-standing TiO2 nanotube (TNT) membranes. Simply by blowing N2 gas onto as-anodized TNTs that are wetted with methanol, TNT membranes produced. The also provides homogeneous honeycomb-like Ti substrates after the detachment of Through second anodization following blowing, comprising hexagonally close-packed regularly ordered clear open ends can be achieved. Characterization using Raman spectroscopy high-resolution transmission electron microscope reveals anatase crystalline graphitic carbon embedded in bottom surface
