We develop a composite photoanode by sensitizing TiO 2 nanorod arrays with PbS quantum dots (QDs) and CdS QDs. Benefitted from additional introduced PbS QDs and CdS QDs onto TiO 2 , the absorption of the composite photoanodes are broaden from UV to visible region. The experimental results showed tha...
