PHOTOCATALYST COMPOSITION OF MATTER

摘要

There is described a photocatalyst composition of matter comprising a support material. A surface of the support material configured to comprise: (i) a first catalytic material for catalyzing the conversion of H2O to H2 and O2, and (ii) a second catalytic material catalyzing reaction of hydrogen with a target compound. The photocatalyst composition of matter can be used to treat an aqueous fluid containing a target chemical compound, for example, by a process comprising the steps of: (i) contacting the aqueous fluid with the above-mentioned photocatalyst composition of matter; (ii) contacting the aqueous fluid with radiation during Step (i); (iii) catalyzing the conversion of water in the aqueous fluid to H2 and O2 with the first catalytic material; and (iv) catalyzing reaction of the target chemical compound in the aqueous fluid with hydrogen from Step (iii) in the presence of the second catalytic material to produce a modified chemical compound.
