Title: A METHOD OF PREPARING METAL NANOCLUSTERS
Abstract:
The present invention relates to a method of preparing metal nanoclusters. The method comprises a step of mixing a miscible solvent with the aqueous precursors, before mixing with an organic solvent and reducing agent. The present invention also relates to metal nanoclusters and use thereof in electrodes. The nanoclusters contain 1 -80 metal atoms and is protected by 1 -80 ligands. The metal atoms are preferably gold, silver, or copper, and the ligands are preferably selected from hydrophobic ligands benzeneselenolate, 4-tert-butylbenzenethiolate, cyclohexanethiolate, 2- phenylethanethiolate, 4-methylbenzenethiolate, and triphenylphosphine.
