Another article out: Hydride formation on defective CeO₂ monitored by NAP-XPS

As a follow-up on our work about reduced ceria nanoparticles, we used near-ambient-pressure XPS to characterize the surface state under H₂ moderate pressure. We show that homolytic cleavege on Ce^(III) sites is the main activation path at 100 °C, forming a significant amount of surface hydrides. This is a key insight to further develop ceria as a self-standing catalyst for low-temperature hydrogenation reactions. Read the article.

Article out: Cerium(IV) as you never saw it

While the literature contains tens of protocols to prepare cerium oxide nanoparticles from Ce(III) precursors, there is still an open question regarding the time at which the cerium oxidation occurs and the role of hydroxide phases in this process. This article identifies an oxyhydroxide phase of Ce(IV) of the chemical formula CeO(OH)₂ as a key intermediate and proposes a crystal structure for it. Read the article.

New article: Influence of the Cobalt Active Site Neighbors in NiCo Nanocatalysts for Phosphine-Assisted Silane Activation

NiCo nanoparticles are active catalysts at room temperature for Si−H bond activation. We designed nanoparticles with a nickel core and a limited amount of cobalt surface sites to clarify which of the two metals was the active site and if the neighbouring atoms influenced the reaction efficiency. The trend in catalytic activity is consistent with cobalt being the active site, and it shows a higher activity when its immediate neighbours are cobalt atoms. Read the article.

New article: Phosphine-Catalyzed Activation of Phenylsilane for Benzaldehyde Reduction

Here, we studied the organocatalyzed hydrosilylation of benzaldehyde with a phosphine, introduced at 10 mol %, and phenylsilane at room temperature.

Very happy to share our first publication proposing the concept of NanoFLP, that is, nanoparticles as partners in Frustrated Lewis Pairs.
