Catalytic processes often occur at solid-liquid interfaces, and understanding what's going on there is challenging. To do this, we used OE-DNP NMR. We could also gain a molecular understanding of catalyst leaching process, a common issue in hererogeneous catalysis. @jacs.acspublications.org
DNP NMR at solid-liquid interfaces is now possible!
In this collaborative work we applied Overhauser DNP to a supported catalyst to gain molecular understanding of interfacial chemistry. @jacs.acspublications.org @ethz.ch

Surface Enhanced Nuclear Magnetic Resonance Spectroscopy at Solid–Liquid Interfaces Using Overhauser Dynamic Nuclear Polarization
While solid–liquid interfaces are ubiquitous, detecting the associated surface sites under ambient conditions remains a grand challenge. Here, we demonstrate an approach to efficiently enhance the NMR...

This great collaborative work is finally out! Proud to see how the advancement of our understanding of 195Pt NMR signatures enables to describe heterogeneous catalysts in such detail.
Are Single Atom Catalysts (SACs) Single-Sites? Not really according to our latest development in 195Pt ssNMR, now out in @nature.com . Our methodology enables to understand the nature and distribution of the coordination environment of Pt SACs! www.nature.com/articles/s41...

13C Chemical Shift of N-Heterocyclic Carbenes in Coinage Metal(I) Complexes and Clusters: trans-Influence and Spin–Orbit Coupling
N-Heterocyclic carbenes (NHCs) are versatile ligands in organometallic chemistry, prized for their strong σ-donating and tunable electronic properties. They are used to stabilize a wide range of motif...

This was a lot of fun! A nice example of how an equation can be used to tackle a long-standing problem in chemistry.
In this work we show how solid-state deuterium NMR can be used to gauge metal-hydride distances in molecular and surface sites, where neutron diffraction techniques are challenging! You find our work in @jacs.acspublications.org
