摘要This paper describes heterogeneous 3-D nanotubular arrays of CdS-TiO2 fabricated by sensitizing anodized 3-D arrays of TiO2 nanotubes with CdS nanoparticles. The radial distribution of heterogeneous arrays on the circumference of Ti wire renders them capable of collecting visible light from any direction. In surroundings where reflection visible light is artificially made by a reflector, the photocurrent output of heterogeneous 3-D arrays is enhanced by similar to 69% at 0 V potential (vs. Ag/AgCl) in a standard three-electrode cell. Based on quantitative measurements of photocurrent output of 3-D arrays under known irradiation intensity from two opposite directions simultaneously, the irradiation intensity of artificial reflection light in our system was determined to be similar to 58 mW cm(-2). By optimizing the length of TiO2 nanotubes and deposition of CdS nanoparticles, heterogeneous 3-D arrays collect direct incident light and artificial reflection light to generate a photocurrent output (normalized to the direct irradiation area) of similar to 13.2 mA at 0 V potential (vs. Ag/AgCl) under 100 mW cm(-2) simulated full light.
