Acid-base (donor-acceptor) properties of solids and relations with functional properties

摘要

Distribution of active surface centers (DAC) spectroscopy is applied to study acid-base properties of solids. Surface characteristics of solid influences interface interaction in which this solid participates. Efficient approach to consider such interactions is to view them as acid-base ones, since acid-base interactions determine adsorption and bonding of organic molecules to solid surface. Paper describes application of method to study surface properties of components of luminescent materials, catalysts, gas sensors, proton membranes and polymer composites, and it was shown that their functional properties strongly depend on distribution of acid-base active surface centers.
