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.
