  • Array of titanium dioxide nanostructures for solar energy utilization
    Patent number: 8920767
    Abstract: An array of titanium dioxide nanostructures for solar energy utilization includes a plurality of nanotubes, each nanotube including an outer layer coaxial with an inner layer, where the inner layer comprises p-type titanium dioxide and the outer layer comprises n-type titanium dioxide. An interface between the inner layer and the outer layer defines a p-n junction.
    Type: Grant
