Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The adsorption of water, methane and hydrogen on a nanocomposite surface based on nanosilica A‐300 modified by C₆₀ fullerene by absorption was studied by low‐temperature ¹H NMR spectroscopy. The thermodynamic characteristics, the size of the interface water clusters, and co‐adsorption effects of combustible gases, i. e. methane and hydrogen, were determined. The distribution of the adsorbed water clusters radii showed several maxima depending on the environment. In hydrogen atmosphere the maximum amount of water was detected in clusters with radii of less than 2 nm. It was found that in contrast to the original silica, the weakly polar organic compounds and water adsorbed on different parts of the SiO₂/C₆₀ nanocomposite surface.</p> </abstract>
