"Bifunctional heterogeneous pair site catalyst" Prof Phillip Christopher, UCSB
Read moreSeminar at IRCELYON
Internal Webinar
Metal catalysts are used for fuel and chemical manufacturing. It is often suggested that heterogeneous metal catalyzed reactions proceed through bifunctional mechanisms where multiple components of the catalyst act cooperatively to facilitate chemical transformations. However, the distribution of potential active site structures on heterogeneous catalysts and required non mean-field kinetic descriptions makes assigning bifunctional mechanisms challenging. We overcome these limitations by synthesizing supported atomically dispersed Rh-WOx pair site catalysts. The relative simplicity of the pair site structure and sufficient description by mean-field modelling enables correlation of experimental kinetics to first principles based microkinetic simulations. Rh-WOx pair sites exhibit a bifunctional ethylene hydroformylation mechanism involving the cooperative reduction of WOx to form the active site, transfer of ethylene from W to Rh, and Rh-W interfacial dissociation of H2. The bifunctional mechanism enables stable >95% selectivity at a product formation rate of > 0.1 gpropanal/cm3/hr in gas phase ethylene hydroformylation. Our results demonstrate that heterogeneous atomically dispersed pair site catalysts enable emergent bifunctional reaction pathways that exhibit high activity and selectivity for reactions exclusively performed in industry using homogeneous catalysts.
