Electro-/Photocatalytic
Solar Fuel Generation
Metal-organic frameworks (MOFs) are a class of porous crystalline materials constructed from metal-based nodes and organic linkers. Due to their ultrahigh specific surface area, porosity, and well-defined structures, well-isolated active sites can be installed in a wide range of MOFs. One of our focuses is the design of water-stable MOF thin films tethered with spatially separated catalytic sites for a range of electrocatalytic applications, including hydrogen generation, oxygen evolution, and CO2 reduction. With the inclusion of light-absorbing organic linkers, these materials can also be utilized as photocatalysts for direct solar-to-fuel conversion.
