摘要：

The aim of the present paper is to test the capability of nonstoichiometric CuO as a conductance sensor material. The surface conductivity changes in CuO were measured in the presence of various donor-acceptor couples. The influence of water and oxygen was investigated as well as NO2 and CO. NO2 had a very high sensitivity. Kinetic schemes of surface reactions are also reported and discussed. (C) 2003 Elsevier B.V. All rights reserved.
