Abstract:

As for the low yield and high consumption of electrolyte in conventional anodization for TiO2 nanotubes, several schemes were proposed to optimize the unit yield. The anode surface area per unit volume of electrolyte and the homogeneity of the electric field are found to affect the unit yield of well-structured TiO2 nanotube besides voltage, F- and water content, reaction time and temperature, etc. Experimental results show that the unit yield over the cylindric electrodes quadruples in comparison with conventional anodization, which is attributed to higher anode surface area and homogeneous electric field. And SEM image indicates that well-structured TiO2 nanotube arrays are fabricated. Thus it can be concluded that the unit yield could be increased by the method proposed in this paper and that our work provides a reference for the bulk preparation of TiO2 nanotube and the energy-saving and emission-reduction in the process.
