Understanding the geometric and basicity effects of organic polymer modifiers on Ru/TiO2 catalysts for CO2 hydrogenation to hydrocarbons†
Modifying inorganic catalysts with basic organic moieties effectively enhances their CO2 hydrogenation activity through CO2 activation, but the effect on C–C coupling rates and selectivity is not as straightforward. In this contribution, we report the encapsulation of Ru/TiO2 catalysts with uniform, conformal, nitrogen-containing polymer overlayers with controllable basicity and morphology. We demonstrate that while basic moieties greatly promote CO2 conversion, it is the morphology of the overlayer that has a significant role in C–C coupling and the production of higher hydrocarbons.
