ABSTRACT
The self-organized TiO2 nanotube layers have attracted considerable scientific and technological interest over the past 10 years motivated for their possible range of applications including photocatalysis, solar cells, hydrogen generation and biomedical uses. The synthesis of 1D TiO2 nanotube structure is carried out by a conventional electrochemical anodization of valve Ti metal sheet. One of the major issues to extend the functional range of nanotubes is to coat homogeneously tube interiors by a secondary material.
The presentation will focus on detail on the coating of the nanotube arrays by various materials using ALD. The deposited materials influence strongly properties of nanotube layers. Experimental details and some very recent photocatalytic [1], solar cell [2], battery [3] and sensing [4] results will be presented and discussed.
