Fig. 4.3 Schematic illustration of the proposed two-phase model, when a is defined as first
minimum of the correlation function and b as the first maximum of the interface distribution
function: a Lm is the most probable distance between the centre of gravity of an Ir (0) nanoparticle
and its adjacent region in the correlation function, and b can be estimated as the disordered ionic
liquid-phase thickness in the interface distribution function [18]
4–5) [24]. The worm-like Ir NPs are polycrystalline, resulting from the aggregation
of individual ‘spherical’ nanoparticles of around 1.9 nm. The volume of the polar
domains of the imidazolium ILs may be controlled by changing the size of the
anions and therefore the size of metal NPs prepared from ionic metal precursors.
For example, Ag NPs obtained by H 2 reduction of silver salts (AgX, X = BF 4 , PF 6 ,
OTf) dissolved in 1-n-butyl-3-methylimidazolium-based ILs (BMIm.X; X = BF 4 ,
PF 6 , OTf and NTf 2 ) and in the presence of n-butylimidazole have a size distribution
