Sept 23: GECAT invited webinar

In relation with the Young Researcher Award from the Catalysis division of the French Chemical Society, I was invited to present our latest results at the "Jeudis du GECAT", a national webinar series that appeared in 2020 and is very successful amongst colleagues. This was a great exchange with the broad catalysis community, thanks all for your feedbacks.

Article on Nickel-Cobalt NanoFLP

Very happy to share our first publication proposing the concept of NanoFLP, that is, nanoparticles as partners in Frustrated Lewis Pairs. We investigated the activation of Si-H bonds by Lewis acid NiCo nanoparticles and a series of phosphines as Lewis base. We demonstrate the key effect of the Tolman cone angle on the success of the reaction, which strongly suggests that we achieved the formation of a NanoFLP in the colloidal solution. This is the key concept of ERC Starting Grant NanoFLP, a project that started in 2018. Read the paper.

Did you say NanoFLP?

We have been proposing for a while to use metal nanoparticles as partners in Frustrated Lewis Pairs. Now, we found that nickel-cobalt nanoparticles associated to well-chosen phosphines likely form such a pair, based on the correlation between Si-H bond activation and the Tolman cone angle of the phosphine: only a tiny range of steric hindrance is suitable, and it is related to the silane bulkiness. We believe we nailed it. Make your own opinion.

Molybdenum mapped out

Molybdenum is a key element of the energy transition. X-ray absortion spectroscopy at the L-edge is an amazing way to analyze it in solids, liquids, composites, etc. Here, we wrote some simple guidelines to interpret the data and we provided a consistent series of spectra for well-known, and less-know, Mo compounds. Read our map.

Green deal on nanocarbides

Here is a dream reaction: no solvent, no waste (except salt), no heat input. Check out how we produced a variety of metal carbide nanoparticles supported on graphite or acetylene black. We also discuss secondary formation of hydrides, metals and oxides using a simple adiabatic approximation.

Water matters

We revisited copper nanoparticles synthesis and showed that, depending on the precursor, the amount of water produced in situ is slightly different. This is enough to modulate the catalytic processes that consume the solvent and reducing agent of the reaction: oleylamine. Read how and why.

Amorphous nanoparticles on the spotlight

Many works focus on the electrocatalytic performances of crystallline metal phosphide nanoparticles. Using a new phosphorus donor, we produced amorphous FeP, we showed that the local structure is similar to these of the crystal, and we found it is more active for HER. Check it out.
