Photocatalyst, Method Of Preparing The Same, Decomposer For Organic Compound Using Photocatalyst, And Device For Organic Waste Disposal Using Photocatalyst

摘要

A photocatalyst according to example embodiments may include a porous metal oxide and an oxygen vacancy-inducing metal. A portion of the oxygen vacancy-inducing metal may be included in a lattice of the porous metal oxide, while another portion may be exposed at the surface of the porous metal oxide. The porous metal oxide may be a divalent or multivalent metal oxide. The oxidation number of the oxygen vacancy-inducing metal may be smaller than the oxidation number of the metal of the porous metal oxide.
