In this report we examined the ability of some natural and synthetic polymers to serve as a catalyst and a template for the polycondensation of silicon and titanium dioxides from their water-soluble precursors – tetrakis (2-hydroxyethyl) orthosilicate (THEOS) and titanium bis(ammonium lactato) dihydroxide (TiBALDH). The catalytic potential of these polymers was estimated spectrophotometrically, and the size, shape and elemental composition of the resulting structures were determined by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). It was shown that albumin and polyethyleneimine can be used to obtain SiO2 and TiO2 particles, respectively. Such homopolymers as the poly-D- and poly-L-lysine efficiently catalyze the synthesis of both silicon and titanium nanocomposite materials.
