| Abstract: | By the co-precipitation method, γ-Fe\-2O\-3 base material has been made. The effects of many dopants on the H\-2 sensitivity were investigated. Especially, the γ-Fe\-2O\-3 gas sensor doped with Ag\-2O was studied in detail. At last, the high sensitivity and selectivity gas sensor of H\-2 and LPG was made with the Ag\-2O dopant and the surface-decorating-coat of Al\-2O\-3 doped with PtO. |
