Methanol is a valuable chemical itself or can be converted to other chemicals. It also can be used as a fuel or can be converted to hydrocarbon fuels. Interest has grown recently to produce methanol by hydrogenation of CO2 instead of by today’s conventional processes that primarily use CO. If CO2 is taken from a bio-power plant and hydrogen produced from renewable electricity (by electrolysis of water), the chemicals or fuels produced via methanol are carbon-neutral. They are referred to as electro-fuels and chemicals. However, methanol synthesis from CO2 is challenging due to the relative inertness of CO2 compared to CO.
Metal-Organic Framework (MOF) materials have great potential as catalysts or selective gas adsorbents due to their versatile porous structure including metal complexes. The combination of a metal complex with known potential for catalyzing CO2 hydrogenation with a suitable MOF structure could be a superior catalyst for methanol synthesis from CO2.
