Abstract
The present invention is directed to multifunctional nanomaterials for photothermal heating and catalytic applications. The present invention discloses a method of photothermally heating a solution. The present method also discloses a method of catalyzing a reaction. Both methods require a step of exposing a solution to at least one wavelength of the electromagnetic spectrum. A gold-iron oxide nanomaterial comprising an iron oxide substrate and discrete gold particles deposited on the substrate is also disclosed.
