Description
Summary:Nanomaterials based on metal oxides are considered. Special attention is given to adsorption, because this step determines physicochemical properties of nanostructured materials. The main processes are considered that occur on the surface of metal nano-oxides in the course of adsorption and the nature of chemoresistance. A model is presented that explains the increasing sensitivity of semiconductor sensor materials with a decrease in the grain size. The potential of the use of metal and metal oxide nanoparticles in catalysis and photocatalysis is discussed. Examples are given for the selective synthesis of α-mercaptopyridine on the surface of TiO 2 with supported silver nanoparticles with a diameter of
