OVERPOTENTIAL AND SELECTIVITY IN THE ELECTROCHEMICAL CONVERSION OF CO2 INTO FUELS

摘要

The invention provides a catalyst and method for producing hydrocarbons from a carbon dioxide source comprising carbides, in particular one or more metal carbides. The one or more metal carbides are formed with one or more elements selected from the group consisting of molybdenum, titanium, tungsten, iron, and tantalum. In one embodiment, the one or more metal carbides are nanostructures. In another embodiment, the one or more metal carbide nanostructures are supported by a carbon substrate. In a further embodiment, the one or more metal carbides nanostructures is dimolybdenum carbide. In still another embodiment, the carbon substrate is graphene or graphene oxide. In another embodiment, the dimolybdenum carbide nanostructures are supported by the graphene or graphene oxide substrate.
