Abstract:
Carbon dioxide conversion and recycling into chemicals and fuels is integral to reducing the adverse effects of human activities on the environment. Dry reforming of methane with CO2 (DRM) is a potentially significant process to convert CO2 and natural gas on a large scale into syngas, that can be used as a chemical/ fuel precursor or as a source of hydrogen. However, the commercial application of this process is yet to be achieved, because of limitations of current heterogeneous catalysts in terms of stability and catalytic activity. This talk will highlight developments in innovative catalyst design with tailormade morphologies and compositions to enhance catalytic activity and inhibit onstream deactivation for dry reforming catalysts. Examples drawn from our work on bifunctional core-shell catalysts will emphasize how catalyst design can sometimes be used to modulate fundamental reaction mechanism and pathways and thereby, significantly enhance the catalyst performance. Insights will be provided on fundamental catalytic structure-property relations for DRM observed experimentally on single atom catalysts, along with comments on the future direction of catalyst development in this field.
