Understanding Catalyst-Pore Wall Interactions
Interaction of immobilized catalysts with pore walls, known as surface collapse (SC), causes loss of catalytic efficiency. The goal of this project is to measure the extent to which immobilized species interact with the pore walls under catalytically relevant conditions. We do this by immobilizing Ru hydrides in porous supports and examining their activity and selectivity during CO2 hydrogenation. SC results in a change in activity and selectivity, enabling the measurement of the amount of SC in various solvents and temperatures. These results will be important to prevent deactivation via surface collapse in all catalytic projects within the CRC.
