Abstract
Official abstract text for this publication.
A multicomponent photocatalyst includes a reactive component optically, electronically, or thermally coupled to a plasmonic material. A method of performing a catalytic reaction includes loading a multicomponent photocatalyst including a reactive component optically, electronically, or thermally coupled to a plasmonic material into a reaction chamber; introducing molecular reactants into the reaction chamber; and illuminating the reaction chamber with a light source.
First claim
Opening claim text (preview).
What is claimed: 1. A multicomponent photocatalyst comprising: by a reactive component chemically attached to a plasmonic material coprecipitation methods, wherein the reactive component is a transition metal alloyed at the surface of the plasmonic material, thereby producing a surface alloy of the reactive component with the plasmonic material to form a surface alloy particle, wherein the bulk of the surface alloy particle is plasmonic material and substantially all of the reactive component is present at the surface of the surface alloy particle. 2. The multicomponent photocatalyst of claim 1 , wherein the plasmonic material is selected from gold (Au), silver (Ag), copper (Cu), aluminum (Al), alloys thereof, TiN, or doped semiconductors. 3. The multicomponent photocatalyst of claim 1 , wherein the plasmonic material is a 2-dimensional material. 4. The multicomponent photocatalyst of claim 1 , wherein a molar ratio of the plasmonic material to the reactive component may be between 1000:1 to 10:1 in the surface alloy. 5. The multicomponent photocatalyst of claim 1 , wherein the plasmonic material has a plasmon resonance at a wavelength between 180 nm and 10 microns. 6. The multicomponent photocatalyst of claim 1 , wherein the plasmonic material has a plasmon resonance at a wavelength between about 380 nm-760 nm of the electromagnetic spectrum. 7. The multicomponent photocatalyst of claim 1 , wherein the plasmonic material has at least one dimension with a size between about 1 nm and 300 nm. 8. The multicomponent photocatalyst of claim 1 , wherein the reactive component is a metal, semiconductor, insulator, single atom species, ionic species, organic molecules, metal complexes, or atomic cluster species. 9. The multicomponent photocatalyst of claim 1 , wherein the reactive component has at least one dimension with a size between an atomic diameter of a metal or ion and 100 nm.
