摘要	A ZnO nanorod array with comparatively long nanorods was successfully prepared on a Ti substrate on a T by applying a. hydrothermal method twice. CdS nanoparticles with high crystallinity were deposited onto the surface of ZnO nanorods through a,galvanostatic electrodeposition method. CdS-sensitized ZnO nanorod arrays after being hydrothermally grown twice with the second growth time of 6 h possessed the best photoelectrochemical performance. The photoinduced current densities at a 0 V bias potential are 23.7 and 15.8 mA.cm(-2) under the illumination of simulated sunlight and visible light, respectively. The monochromatic incident photon-to-electron conversion efficiency values at the wavelength of 380-520 nm are in the range of 50-60%, which indicated its high photoelectric conversion efficiency. The contribution from visible light is significantly higher than that from UV light. The prepared photoanodes in the present work exhibit a potential application in photoelectrochemical hydrogen production from water reduction under sunlight.; A ZnO nanorod array with comparatively long nanorods was successfully prepared on a Ti substrate on a T by applying a. hydrothermal method twice.
