- Аннотация: One-dimensional single crystalline TiO2nanorod arrays with different lengths were prepared by control-ling the hydrothermal cycles, which were successfully sensitized with CuInS2quantum dots by assemblylinking cycles, and their optical absorption properties and photoelectrochemical properties were investi-gated. 6 m-TiO2nanorod electrodes with the CuInS2quantum dots sensitization of three linking cycleshad the best photoelectrochemical properties and short-circuit current density, such as the short-circuitcurrent density are 27.3 times higher than that of pure 6 m-TiO2nanorod electrodes. The reason maybe attributed to the suitable internal surface area of TiO2nanorod, with the increasing of the adsorptioncontent of CuInS2quantum dots to generate much more photo-induce electrons. Moreover, it will alsoenhance the interface connection between TiO2nanorod and FTO conducting substrate, which favors toreduce the recombination of photo-induced electron–hole pairs.
