摘要：

A novel electrodeposited CDs nanoparticle-modified highly-ordered TiO2, nanotube-array photoelectrode and its application to photoelectrochemical cells is reported. Results show formation of a thin, nanoparticulate Us layer, comprised of sphere-like 10-20 nm diameter nanoparticles, on the anodic synthesized TiO2 nanotube-array (inner diameter of 70 nm, wall thickness 25 mn and ca. 400 nm length) electrode. The resulting CdS-TiO2 photoelectrode has an as-fabricated bandgap of 2.53, and 2.41 eV bandgap after sintering at 350 degrees C in N-2 ambient. Photoelectrochemical properties are described in detail. (c) 2005 Elsevier B.V. All rights reserved.
