Abstract

We proposed a new approach on preparing titania or titanate nano- or micro-rod arrays on metallic titanium (α-Ti) surfaces by coating a layer of sodium tetraborate or potassium metaborate on titanium substrates and subsequent thermal treatment. Thin-film X-ray diffraction analysis indicated that the sodium tetraborate gave rutile (TiO2: PDF# 21-1276) micro-rod array. The potassium metaborate, in contrast, yielded a potassium titanate (K2Ti6O13: PDF# 40-0403) nano-rod array. The rods in the arrays grew almost perpendicular to the substrate surface.
