Anodization Parameters Influencing the Growth of Titania Nanotubes and Their Photoelectrochemical Response
Figure 7
Comparison of photocurrent density at 1.0 V (versus Ag/AgCl) of as-anodized and calcined TNTs prepared in pH 4 electrolytes (a) at different electrolyte temperatures and (b) using different voltage ramps prior to constant voltage of 20 V. All the photocurrent measurements were obtained using 10 ppm methyl orange solution from 300 W halogen lamp at scan rate of 20 mV/s.
