“…. This has also been reported for ligands such as NHC-carbenes [87] or diphosphites [88] where structural modification of the backbone with bulkier groups led to smaller NPs. Multidentate ligands interact more strongly with the surface of the NPs and generally provide better stabilization, and smaller sizes, as can be observed for small dendrimers [89].…”

“…surface like the presence of incompletely reduced metal atoms as well as that of defects sites or smooth terraces. CO is further considered as a probe molecule to determine the location of coordinated ancillary ligands in particular when studying its mobility at the metal surface (see section 3.6.2) [87].…”

“…Indeed, preferential adsorption of the ligand on some facets or selected topological sites has consequences on the final morphology and reactivity of the NPs (vide infra) and is of outmost importance for catalytic applications (Fig. 8) [87], [208]. -the high reactivity of the target systems which explains why most studies have been carried out on the most stable MNPs i.e.…”

“…Whilst N-heterocyclic carbenes (NHC) were well-known as ligands in ruthenium complexes for olefin metathesis, the ability of carbenes to stabilise metal nanoparticles was first reported in ILs and then in conventional solvents [45], e.g. by using NHC carbenes [46][47][48][49].…”

Ionic Liquids (ILs) in Organometallic Catalysis

During the last decade, a great interest in the preparation of uniform nanocrystals has offered efficient synthetic strategies to precisely engineer metal, metal oxide and alloy at the nanoscale. Due to their physicochemical properties, ionic liquids (ILs) simultaneously demonstrated their potential in different areas such as nanocrystal synthesis, catalysis and energy. As a result, ionic liquids have been employed for the preparation of monodisperse nanocrystals and the control of their size. This chapter highlights the most promising methods for the synthesis of uniform nanocrystals in ionic liquids which act as a solvent, stabiliser, reducing agent and even precursor. As a result, successful preparations of nanoparticles in the presence of ILs are now available for both noble and earth-abundant elements such as gold, platinum, iridium, silver, palladium, ruthenium, rhodium, copper, nickel, cobalt and iron.The formation mechanisms of these nanocrystals are discussed as well as our mechanistic understanding in conventional organic and aqueous solvents. In addition, the IL approach is compared to leading methods in conventional solvents to make possible the identification of general principles for most metallic elements. By analogy with conventional solvents, these strategies can be adapted to the preparation of semiconductor nanocrystals. These achievements are going to drive the identification of relationships between the nature of ILs components, the physicochemical properties of ILs, the formation of nanocrystals in ILs and the resulting performances of these nano-objects.
