The introduction of rare earth elements into TiO 2 can effectively improve the electron-hole separation of TiO 2 and prolong the visible light response of TiO 2. Cerium (Ce) shows variable valence ...

The performance of a fuel cell—a device that converts chemical energy into electrical energy—depends on how well the ions can move through the cell's material. Most current fuel cells operate at high ...

Copper-doped titanium dioxide represents a versatile photocatalytic material that extends the light response of pure TiO2 into the visible region while enhancing charge separation and redox activity.

Titanium dioxide (TiO2) nanotubes have emerged as a versatile nanomaterial platform for energy conversion and storage technologies. Typically fabricated by electrochemical anodization of titanium in ...
