Abstract

The acid–base properties of the surface of SiO₂ and Al₂O₃ nanoparticles obtained by various methods are characterized by the adsorption of acid–base indicators and dynamic pH-metry. The effects of the applied synthetic approaches (including liquid phase and plasma-chemical processes, as well as electric explosion) on the functional composition of the studied materials (predominance of Lewis or Brønsted acid or basic sites with different pK_a values) and properties of suspensions prepared using the synthesized nanopowders are studied.
