摘要：

Strong conductivity changes in ex-bismuth molybdate semiconductor material on exposure to minute levels of alcohol have been studied to demonstrate its use in breathanalyser. High bulk mobility of oxygen vacancies and rapid catalytic activity of palladium in reduction imparts it high sensitivity (similar to 10 ppm) for alcohol vapors.
