| titleOfInvention | Nano composite oxide sensitive material for formaldehyde and benzene |
| abstract | The invention relates to a nano composite oxide sensitive material for monitoring formaldehyde and benzene. The nano composite oxide sensitive material is a nano powder material consisting of the components in percentage by mass: 50-60 percent of Bi2O3, 20-30 percent of TiO2 and 15-25 percent of MnO2. A preparation method comprises the steps of co-dissolving bismuth salt, titanium salt and manganese salt in a citric acid aqueous solution, performing ultrasonic oscillation until the solution is clarified, adding a proper amount of ethylene diamine tetraacetic acid disodium under high-speed stirring to keep the solution clarified, continuing to stir, dropwise adding ammonia water to adjust the pH value of the solution, stewing, aging, filtering and drying the product, performing full grinding, and roasting in a box type resistance furnace to obtain the powder material consisting of the Bi2O3, TiO2 and MnO2. A formaldehyde and benzene catalysis luminous sensor made of the composite oxide sensitive material provided by the invention is wide in linear range, high in selectivity and high in sensitivity, and can monitor the formaldehyde and the benzene in air on line without influence by coexistence substances. |
