Synthesis of au, pd, pt or ag nano- or microcrystals via reduction of metal salts by cellulose in the ionic liquid 1-butyl-3-methyl imidazolium chloride |
| abstract |
The invention refers to a preparation method for nano- or microcrystals of Au, Pd, Pt or Ag comprising the steps of: a) preparing an ionic liquid mixture of cellulose and at least one metal salt selected form the group consisting of Au, Pd, Pt and Ag in l-butyl-3-methylimidazolium chloride; and b) (i) thermally inducing a reduction of the metal salt with cellulose by heating of the mixture to a temperature in the range of 50 to 250°C; or (ii) photoreduction of the metal salt by irradiation of the mixture with light having a wave length in the range of 200 to 800 nm. |
