MULTIVALENCE PHOTOCATALYTIC HETEROGENEOUS MATERIALS FOR SEMICONDUCTORS

摘要

Described herein are heterogeneous materials comprising a p-type semiconductor comprising two metal oxide compounds of the same metal in two different oxidation states and an n-type semiconductor having a deeper valence band than the p-type semiconductor valence bands wherein the semiconductor types are in ionic communication with each other. The heterogeneous materials enhance photocatalytic activity.
