Fractal-percolation ZnO nanosystems were obtained in the form of interconnected nanowires with a close to stoichiometric elemental composition and with hexagonal lattice parameters suitable for zinc oxide. For the first time, the possibility of recognizing such reagents as acetone, methanol and methane-butane mixture is shown on the basis of studies of current-voltage characteristic in fractal-percolation ZnO nanosystems. The assumption that charge transfer and, as a result, current voltage characteristics are defined by radiuses of separate nanowires which it is less, than length of Debye screening is made. Thus the adsorption-desorption reactions of various reagents on the surface of the nanowires lead to the formation of clusters, various on a configuration, in turn provide current voltage characteristics, different in character.
