Gas sensitivity of ZnO-based ceramics to vapors of saturated monohydric alcohols

The sensitivity of electrical conductivity of ZnO-based ceramics to vapors of saturated monohydric alcohols was investigated. Its interconnection with physicochemical parameters of alcohols: molecular mass, entropy, Gibbs energy, enthalpy, the bond breaking energy of С–О and О–Н molecular bonds was analyzed. The selectivity of gas-sensitive properties toward vapors of saturated monohydric alcohols, seen in temperature, kinetic and concentration dependences of response was found. A model linking the sensor response, entropy and molecular mass was proposed.
