Abstract:
Series of materials and devices based on metal oxide (hetero)nanostructures consisting of surface controlled quantum dots and rods building-blocks have been fabricated utilizing low-cost and large scale aqueous chemical growth. The electronic structure and basic structural, optical, and photoelectrochemical properties of such novel visible light-active oxide semiconductors based on vertically oriented quantum rod-arrays have been thoroughly investigated. Doped and/or quantum dot sensitized bundle of iron oxide quantum rods which by intermediate band effects enable a full visible absorption profile while still being stable against photo-corrosion for efficient and low cost solar hydrogen generation by direct water splitting at neutral pH allowing therefore the use of the largest free natural resource on Earth, that is seawater, as unique electrolyte...
