Biography

Prof. Abdelkrim El Kadib received his Ph.D. in 2004 from Université Paul Sabatier de Toulouse (LHFA), France. From 2005 to 2008, he worked as post-doctoral fellow at the Université de Pau et des Pays de l’Adour, Ecole Normale Supérieure de Chimie de Montpellier and Total Petrochemical (Belgium). He next moved to Queen’s University in Kingston (Canada), before joining iNANOTECH-MAScIR in Morocco as Associate Researcher. Presently, he is Full Professor at the Euromed University of Fes (Morocco) and a team leader of Hybrid Functional Materials. His research focuses on the synthesis and characterization of new organic–inorganic hybrid materials, including biomimetic and bioinspired hybrids, mesostructured organosilicates, and phosphorus-based metal oxide mesocrystals and their application in catalysis, energy conversion, and nanomedicine. Prof. El Kadib has published over 85 publications in high impact factor chemistry journals (most of them with IF > 5) and 9 patents

Abstract

Surface-reactive phosphorus-conjugated nanomaterials

Phosphorus plays an important role in our daily life as illustrated by the ubiquity of phosphorus-containing fragments in drugs and commodity materials. In chemistry, a vibrating activity was associated to the implementation of phosphine in coordination chemistry and catalysis, polyphosphazene in polymer-based flame-retardants, and metal phosphide in the next generation of energetic materials.

Owing to a set of exciting features, phosphorus-containing reagents emerged as powerful surface-coupling derivatives, allowing the transformation of solids with little allure to highly reactive materials. This comparatively recent approach outperforms the hitherto used conventional silylation achieved through post-grafting of alkoxy silyl derivatives.

In this context, we recently engaged a deeper understanding on surface functionalization of a variety of nanomaterials using phosphorus derivatives. This includes covalent dendritic framework,1 porous metal oxide,2 graphene sheets,3,4 cellulose nanocrystals5 and other nano-sized objects including tubular halloysite nanoparticles.

Interestingly, the presence of phosphorus imparts these nanomaterials with high surface-reactivity, outstanding thermal and chemical stability and even interesting biological response when these materials are used as antibacterial devices. Overall, the use of phosphorus as coupling agents provides a new channel of exciting possibilities in chemistry and material science and is suspected to broaden the library of available phosphorus-based materials.
