Counter-ion effects of silver salt on the production yield of silver nanoparticles in alcohol reduction process

- Silver nanoparticles were prepared with silver salts of various counter-ions via alcohol reduction process.
- Reduction degree of silver ions was very much dependent on the kinds of counter-ions.
- Inorganic silver salts containing fluoride (AgF, AgPF6, and AgBF4) showed a high reduction yield.
