One of the topics being currently investigated in our laboratory is the development of nanometric tools for catalysis. These tools are based for example on carbon nanotubes (CNTs) which have attracted considerable interest in the field of nanotechnology due to their unique properties and have emerged as promising supports in heterogeneous catalysis. Indeed, metallic assemblies on nanotubes are consistent materials which show better catalytic properties than catalysts prepared on other forms of carbon. In addition, CNTs are electronically active and are able to stabilize transient higher oxidation states of the supported metals. These intrinsic properties make CNTs ideal platforms for metallic catalyst particles. Our group has been involved in the supramolecular assembly of metallic nanoparticles on carbon nanotubes. In this regard, we developed an original layer-by-layer approach for the robust anchoring of metals on CNTs and used of the resulting nanohybrids in the catalysis of organic transformations and energy related processes. The synthetic chemistry of Gold (e.g. Angew. Chem. 2011, 50, 7533, Chem. Commun. 2014, 50, 15251, Catal. Sci. Technol. 2016, 6, 6476), Palladium (Catal. Sci. Technol. 2015, 5, 2388, ChemCatChem 2015, 7, 2318), Ruthenium (Chem. Commun. 2015, 51, 1739, ChemCatChem 2016, 8, 1298), Rhodium (Catal. Sci. Technol. 2015, 5, 4542, Chem. Eur. J. 2015, 21, 7039, ChemCatChem 2017, 9, 2091), and non-noble Nickel (Chem. Select 2017, 2, 5891) was accordingly investigated. Gold nanohybrids were also valorized in energy related applications such as the oxygen reduction reaction (Nanoscale 2015, 7, 17274), or the conversion of CO2 into fuels (ChemSusChem, 2016, 9, 2317).
