TiO2 photoelectrodes are made using the "dip-coating" technique with colloidal suspensions of TiO2 nanopowders. Two different commercial TiO2 powders are selected with nanocrystals having different porosity and somewhat different crystal structure. Photoelectrodes are characterized using a practical two-electrode photoelectrochemical cell arrangement. Differences in open-circuit photovoltage and short-circuit photocurrent are reported and explained based on initial powder characteristics. Differences in time response found are also explained. © 2002 Elsevier Science B.V. All rights reserved.
