Title: Water purification

Abstract

Production of decontaminated water from contaminated water using a vessel, an inlet to the vessel wherein the contaminated water is introduced into the vessel, an outlet to the vessel wherein the decontaminated water is removed from the vessel, a plasmonic-photocatalyst membrane connected to the vessel, plasmonic nanoparticles or nanostructures connected to the plasmonic-photocatalyst membrane, and a source of ultraviolet light that directs ultraviolet light onto the vessel, the plasmonic-photocatalyst membrane, the plasmonic nanoparticles or nanostructures, and the contaminated water to produce the decontaminated water from the contaminated water.
