The effects of adsorption of boron containing molecules on the optical properties and reactivity of colloidal silver particles (4 nm diameter) were studied. The absorption spectra of silver particles surface modified by tetraalkoxyborones are significantly different from that of the primary silver sol. A decrease and broadening of the surface plasmon absorption band are accompanied with the formation of a distinct long-wavelength absorption band. The Fermi potential of silver particles complexed on their surface by tetraethoxyborone is shifted towards a negative potential, and lies between - 0.2 and + 0.153 V.
