Tuesday publication post! Have you ever thought about what a structural metamorphesis of Mo-based zeolite imidazole framework-8 (Mo-ZIF-8) looks like at the nanoscale under diverse gaseous atmospheres? The authors of this newest work have looked at zeolite imidazole frameworks (ZIFs) under a reductive atmosphere using the #AtmosphereAX.

In this study, the structural transformation of Mo-related materials—Mo2C, Mo nanoparticles, Mo nanoclusters, and even Mo single atoms (Mo-SAs) on porous N-doped carbon (PNC) was investigated under reductive atmosphere at various temperatures.

But that’s not all! Our study doesn’t stop at oAbservation; it dives deep into understanding the underlying mechanisms driving this evolution. Besides in situ imaging, the authors also looked into the performance of Mo-related materials/PNC in the electrochemical nitrogen reduction reaction (NRR). The Mo-SA/PNC materials showed a remarkable NH3 yield rate and Faradic efficiency at a potential of -0.2 V versus reversible hydrogen electrode.

These findings are great guidelines for the rational design in metal-based metal-organic frameworks and their practical application.

The video shows the decomposition of Mo-ZIF8 in a hydrogen/argon environment.
