Stable platinum nanocrystals with small diameters (1.0–2.3 nm), that are stable for a long time, with narrow size distributions were easily and reproducibly prepared without any additional stabilizers in glycol, glycerol, the ionic liquids (ILs) 1-n-butyl-3-methyl-imidazolium tetrafluoroborate [BMIm][BF4] and N-butyl-N-trimethyl-ammonium bis (trifluoromethylsulfonyl ) imide [N4111][NTf2] or diphenylmethane (CH2Ph2) by thermal, photolytic or microwave ...
