L'Association Européenne de Cristallographie (ECA) organise depuis 2021 des "webinaires déjeuner". Les groupes d'intérêt spéciaux (SIG) et les groupes d'intérêt général (GIG) de l'ECA organisent à tour de rôle un webinaire adapté à la communauté des cristallographes au sens large. Le quatorzième webinaire sera diffusé le 6 octobre 2022 et le thème est Metal-Organic Frameworks as Platforms for Hosting Molecular and Bio-Catalysts for Carbon dioxide Hydrogenation. Dans le cadre de cette conférence, le Dr Mehlana soulignera également le rôle joué par l'AfCA dans la promotion de la science sur le continent africain. Inscriptions ici.
Organometallic compounds such as pincer complexes have been known to be highly active towards carbon dioxide hydrogenation. On the other hand, crystal engineering provide the design strategies for anchoring molecular complexes in metal-organic frameworks (MOFs). Combining these two areas would offer new materials which are highly active towards the conversion of carbon dioxide to high value chemicals. In our approach we have utilized diamine, diimine and pincer based complexes to build new MOFs with catalytic activity. Our research also explores new methods for introducing catalytically active sites in MOF pores. The successful synthesis of molecular catalysts inside MOF pores is confirmed by both spectroscopic and diffraction techniques. Results obtained from this work demonstrates that the introduction of molecular catalysts inside the MOF pores enhances the catalytic activity for the conversion of carbon dioxide to formic acid.
