It was found that the rate of reductive sorption of molecular oxygen on dispersed silver-KU-23 sulfo-cation exchanger nanocomposites depends substantially on the ionic form (H+, Ag+, Na+ forms) of the nanocomposite.

It was established that the observed dependence is due to the influence of the composition of the medium in pores of the ion-exchange matrix, which serve as nanoreactors, on the rate of the chemical reaction between silver nanoparticles and dissolved molecular oxygen.
