Hollow TiO2 nanotubes were synthetized by ALD coating MWCNTs templates. Implementation of thin layer buffer improves deposition of TiO2 on surface of MWCNTs. A thin Al2O3 layer gives structural stability for thin TiO2 coatings. TiO2 anatase is the only crystalline phase present after template removal. Through surface engineering, is possible fabricate conformal thin TiO2 nanotubes.
