“…14 For the synthesis of small (r10 nm) transition metal oxide clusters, solution based methods are often used, such as sol-gel techniques, microemulsions, micelle/reverse micelle methods or precipitation. [15][16][17][18][19][20][21][22][23] A disadvantage of all these techniques is the inevitable impact onto the product shape, structure and purity. An alternative approach is based on the evaporation of vanadium oxide with lasers, but has undesired side effects such as the production of highly reactive fragments, charged complexes and other unwanted by-products.…”

“…17,18 To prevent aggregation, NPs must be stabilized by the use of capping agents such as (water-soluble) polymers, quaternary ammonium salts, surfactants, ligands or polyoxoanions, providing electronic and/or steric protection. 19,20 In this context, ionic liquids (ILs), dened as low temperature molten salts, have emerged as one of the most important and the most investigated media for the synthesis of metal NPs. [21][22][23][24] Moreover, an advantage of using ILs is that stabilizing additives such as ligands, polymers and supports are not required.…”

“…Thermal decomposition of the metal organic Pt-precursor released volatile fragments of the organic ligands, which can be removed from the reaction mixture under reduced pressure to give ligand-free Pt-NPs with little contamination [55][56][57][58]. The Pt-NPs should then attach to the thiol groups on the graphene surface and/or use the -SH functions as nucleation centers.…”
