Tin– and Titanium–Oxygen Nanostructures on the Various Hydr(oxides) Surfaces

Tin– and titanium–oxygen nanostructures were synthesized by molecular layer-by-layer deposition from the gaseous phase onto various substrates (SnO₂, SiO₂, AlOOH) using (in the course of synthesis) hydroxyl and methoxy surface groups. The electrokinetic (electrokinetic potential, isoelectric point) and adsorption (adsorption of potential-determining ions, the point of zero charge) properties of prepared composites were studied as a function of pH of NaCl background solutions. Synthesis conditions that make it possible to obtain (on the boehmite substrate) nanostructures with electrosurface characteristics similar to the properties of corresponding bulk oxides were determined.
