| Abstract: | The structure of SnO2 and it' s gas sensitive principle for CO were stated simply in this article. Aimed at some disadvantages which occurred in gas sensing material for CO based on SnO2 generally such as high temperature of work and wasteful electricity, this article put forward several methods to reduce the work temperature of the gas sensing material: enlarging specific surface area, adding some suitable impurities and catalyzer. |
