CO2 from combustion and industrial processes holds great potential as an abundant carbon feedstock for the synthesis of fuels and chemicals. CO2 can be hydrogenated to high value products using a renewable hydrogen source, generating carbon neutral fuels and chemicals. In current industrial processes CO2 is often present in the syngas feed or formed as a side product. Developing heterogeneous catalysts for CO2 conversion is thus critical for improving existing processes as well as transitioning to CO2 as a sustainable globally distributed carbon feedstock. We have investigated transition metal phosphide catalysts for the hydrogenation of CO, CO2 and their mixtures and have developed catalysts with high stability under changing feed conditions. Transition metal phosphide catalysts were found to be active for the synthesis of a range of products including methane, hydrocarbons, methanol and higher alcohols. Promoters were found to have a large impact on product selectivity. Transition metal phosphides are novel catalysts for CO2 activation and hold great promise for the utilization of CO2 as a new carbon feedstock.
