KINETICS OF SILVER NANOPARTICLES FORMATION IN THE PRESENCE OF NUCLEATION CENTERS
Journal Title: Праці Наукового товариства ім. Шевченка - Year 2017, Vol 48, Issue
Abstract
The kinetics of formation of silver nanoparticles via reduction of silver nitrate by hydrazine hydrate in the presence of added into the reaction medium silver nucleation centers with mean diameter 15 nm have been investigated using photocolorymetry method. It was shown that such process can be described using simple autocatalytic scheme A + B 2B. Kinetic parameters of silver nanoparticles growth have been calculated and it was found that obtained from the kinetic data values of concentrations of nucleation centers are in good agreement with the concentrations of silver surface atoms of added seeds. The possibility of stable controlling of size of obtaining silver nanoparticles by starting concentrations of silver nitrate and nucleation centers has been shown.
