A thermal neutron and an X-ray photon get into a fight....who's winning 🤠🤠? Read about using neutron versus anomalous X-ray diffraction for occupancy determinations in heterobimetallic clusters in our new paper out in JACS. pubs.acs.org/doi/10.1021/jac…

Happy to share the final work from my PhD! We built a robot to automate collection of electrochemical reaction rate data and used it to investigate CO2 reduction mechanisms at several immobilized metal tetrapyrroles. pubs.acs.org/doi/10.1021/acs…

We found evidence of complex rxn mechanisms involving phenomena such as V-dependent mixed control. These manifested as apparent reactant order dependencies that changed dramatically with applied V, and were only discernable with kinetic data collected over many rxn conditions.

We designed a robot to collect CO2RR rate data over a wide range of conditions (30+). Results suggest complex electrocatalytic phenomena like coverage effects & mixed control are prevalent even amongst well-known immobilized metal tetrapyrrole catalysts 👇pubs.acs.org/doi/10.1021/acs…

Very happy to share a highlight of my PhD! As a design strategy for developing a new C-C bond forming electrocatalyst, we sequentially “electrified” a thermochemical hydroformylation (HFN) catalyst to access analogous electrochemical reactivity. doi.org/10.1021/jacs.4c02992

As we dream about further expanding the types of reactions we can facilitate electrochemically, perhaps we can think about leveraging thermocatalytic precedent in this very direct and experimentally tangible way!
