The results of study of anodic dissolution process of silver in alcoholic solutions of salts applied to the synthesis of nanoparticles of silver are presented. Silver electrode in alcoholic solutions of LiClO4 dissolves at anodic potentials, higher than 0.6 V. Silver passes to the solution in the form of soluble complexes. As a result of further processes (oxidation-reduction) in electrolyte metallic silver nanoparticles are acquired. The silver nanoparticles were indentified using spectroscopic techniques; SEM, TEM, XPS. The mechanism of the process is proposed.

Przedstawiono wyniki badań anodowego roztwarzania srebra w alkoholowych roztworach soli oraz możliwość wykorzystania tego procesu do syntezy nanoczastek metalicznego srebra. Elektroda srebrna roztwarza się w alkoholowych roztworach LiClO4 przy potencjałach anodowych wyższych od 0.6 V. Srebro przechodzi do roztworu w postaci rozpuszczalnych kompleksów. W wyniku wtórnych procesów (oksydacyjno redukcyjnych) w elektrolicie tworzą się nanocząstki metalicznego srebra. Nanocząstki srebra były analizowane przy pomocy technik SEM, TEM, XPS. W pracy zaproponowano mechanizm procesu syntezy.
