“CO2MET”: Rational Design of Functional Catalysts for CO2 Methanation
The global warming induced by the rising concentration of greenhouse gases (GHG) from anthropogenic activities is a threat that has become the primary focus of environmental research. Main attention is focused on the control of CO2 (ca. 82% of GHG) emissions, and the development of cost-effective CO2 capture and storage technologies is an urgent demand in the imperative transition to global carbon-free energy sources. To stimulate the economy of these technologies, the so-called valorisation of CO2 strategy prospects for new concepts and opportunities in CO2 utilisation, including the synthesis of a wide variety of value-added chemicals and energy carriers (fuels). Hence, CO2 conversion into fuels not only holds promise to prevent GHG emissions but also to contribute to meeting the rapidly growing global energy demand.
In this scenario, the catalytic CO2 reduction with H2 is a promising chemical transformation to produce energy carriers such as methane, CH4, synthetic natural gas (SNG). Indeed, SNG is a versatile fuel that can be easily stored and dispatched via the existing natural gas pipelines, offering significant advantages compared to gaseous or cryogenic H2.
