In the present work, we show that fully functional self-organized TiO2 nanotube layers can be electrochemically grown with an unprecedented growth rate if lactic acid (LA) is used as an additive during anodization. The main effect of LA addition is that it allows performing nanotube growth at significantly higher anodization voltage than in the LA free case, and this without dielectric oxide breakdown (鈥渂urning鈥?. As a result, for example, 15 渭m tube thick nanotube layers, suitable for a use in dye-sensitized solar cells (DSSCs) can be grown in 45 s and 7 渭m tubes suitable for water splitting can be grown in 25 s.
