In addition to activity and selectivity, stability of dilute alloy catalysts is also an important metric for their commercial applications. In this paper in @J_A_C_S we shed light on the factors that govern the stability of this class of materials.

New paper (rdcu.be/eIEO3) in @NatureCatalysis used first-principles neural network MD and interpretable ML to uncover simple predictive models for the stability of metal nanoparticles on oxide supports. We used the model to identify sinter-resistant supports for Pt.
Paper @J_A_C_S (@UMichChE ) describing how reactive chemical environment controls charge carrier selectivity and photovoltage at electrocatalyst/semiconductor junctions in solar water splitting. Critical for understanding these systems pubs.acs.org/doi/full/10.102…
Many desired reactions lack catalytic solutions. Co-optimizing membrane–catalyst functionalities at molecular level could improve performance. New article in @NatChemEng (@UMichChE) nature.com/articles/s44286-0… examine the integration strategies, focusing on shale-gas conversion.

We developed an additive manufacturing approach to co-optimize hierarchical membrane/catalyst systems for oxidative coupling of methane (match the transport and reaction rates). Published in Nature Materials. I hope this free link work rdcu.be/doqnf
Diversity of mechanisms that we discovered for relatively simple ethylene epoxidation reaction on Ag suggests that the richness and complexity of surface chemistry are likely a rule rather than an exception in heterogeneous catalysis pubs.acs.org/doi/full/10.102…

I'm officially a professor now! Best wishes to everyone starting new positions this year (inside & outside of academia)🙂
Our paper on Elucidating the Roles of Local and Nonlocal Rate Enhancement Mechanisms in Plasmonic Catalysis was recently published. Congrats Rachel pubs-acs-org.proxy.lib.umich…
