[Know Tungsten] Doped Yellow Tungsten Oxide

Doped yellow tungsten oxide, also known as doped tungsten trioxide, is a good catalyst. Compared with the common yellow tungsten oxide, the photoelectric conversion efficiency and photoelectric catalytic activity of the doped tungsten trioxide have been improved. For example, Fe is doped to form Fe2O3 and Fe3+ can capture the photo electron, which inhibits the recombination of electron and hole.
