| Shrnutí: | Title screen The work considers the influence of the morphological characteristics of the AgNPs (form, sizes of silver nanoparticles (AgNPs), the average size of the area) from the composition of the reducing agent and their influence on the optical characteristics and electrochemical activity of the sensor based on the AgNPs to H2O2. The intensity of the optical spectra of absorption AgNPs and the electrochemical activity of the sensors based on them correlate with the size and shape of the particles. It is shown that the greatest electrochemical activity of H2O2 is possessed by AgNPs-based sensors obtained by using sodium citrate. The reason for increasing the electrochemical activity of the sensor based on the AgNPs obtained in the presence of the soft restorer of sodium citrate is an increase in the area of their active surface 1.3–2.7–3.3 μm2 due to the non-spherical form of particles (triangular, prismatic, pyramidal form), compared with spherical particles obtained using borhydridicitrate and borohydride-based reducing agents Текстовый файл |
