Stanford University is partnering with Susteon to develop a “Modular System for Direct Conversion of Methane into Methanol via Photocatalysis.” This DOE project awarded under DE-FOA-0002006 aims to develop a process-intensified catalyst for photochemical conversion of methane to methanol. The project will overcome challenges associated with the high-temperature activation of methane by employing a novel photocatalytic methane activation step that takes place at a gas-water interface such that methanol can be formed at room temperature. Photons are used to excite hydroxyl radicals in aqueous media, which then excite methane molecules to form methanol on the catalyst surface. This project will identify and develop new catalysts and photoactive materials in combination with a proposed reactor design capable of converting associated natural gas to high-value products at remote sites throughout the United States.
