Catalytic CO2 Hydrogenation and Off-gas Upgrading Strategies

Abstract

The steady increase of CO2 in the atmosphere owing to the excessive use of fossil fuels is seriously threatening the future of humankind by accelerating climate change. However, catalytic chemistry can turn this harmful greenhouse gas into a renewable source of carbon to provide an alternative feedstock for producing high-value hydrocarbon fuels, chemicals, and polymers as a carbon capture and utilization (CCU) strategy. Among the proposed CCU options, catalytic CO2 hydrogenation is attractive because the process is very similar to the well-established CO hydrogenation.
