Hello Dear Scientists, I have read with interest many articles named 'Influence of a sputtered compact TiO2 layer on the properties of TiO2 nanotube photoanodes for solid-state DSSCs' and many more. In my doctoral thesis, I coated Ti film with a thickness of 3 micrometers on FTO with a magnetron sputtering device. However, despite my many attempts with the anodization method, I could not meet the conditions to obtain TiO2 nanotubes. None of the articles specified the amount of ethylene glycol solution prepared, mixing speed and time, I would be very happy if you could share them with me. Otherwise, unfortunately, there is not enough material to make more experiments. I would really appreciate if you can help. Thank you.
