| Abstract: | This chapter focuses on the functionalization of heterogeneous catalysts of group 8–10 by capping ligands. The synthetic approaches used for the introduction of ligands were particularly looked at, and according to the type of ligands, three main approaches were used: the colloidal formation of metal nanoparticles (MNPs) stabilized by ligands and their subsequent deposition over a solid support, the direct synthesis by colloidal formation of the ligand-capped active phase in the presence of the support, and the ligand functionalization of a previously synthesized heterogeneous catalyst. Depending on the aim of the study and the catalytic application, one of the synthetic strategies was selected. The ligands were shown to have a range of effect on the catalytic performance of the catalyst by tuning the electronic properties of the metal(s), the steric hindrance at the metal surface, or blocking some of the catalyst active sites. These modifications can therefore influence the activity, the selectivity, and/or the stability of the materials, and as such, ligand functionalization appears as a powerful method to fine-tune the properties of heterogeneous catalysts. |
