A nanoarchitectured photoelectrode based on TiO 2 inverse opals and CdS quantum dot sensitization is used for solar hydrogen generation. The 3D percolated periodical pore structure of TiO 2 inverse opal provides a high surface area for sensitizer loading plus a good electrical transport path and intimate contact with the electrolyte, all of which contribute to the photoelectrochemical performance. The inverse opals provide a unique platform for further hybridization with other photoactive nanostructures and enhancement of light manipulation.
