| titleOfInvention | Low-temperature catalytic luminescence sensitive material of formaldehyde and ammonia |
| abstract | The invention relates to a low-temperature catalytic luminous sensitive material of formaldehyde and ammonia, which is characterized in that Pt atoms are doped with Fe 2 O 3 、In 2 O 3 And V 2 O 5 To form the composite powder material. The preparation method comprises the following steps: mixing malic acid water solution of ferric salt with citric acid water solution of indium salt and ammonium metavanadate, adding glucose and isopropanol, then adding chloroplatinic acid, rotationally evaporating to remove one third of water, then adding agar powder while keeping a certain temperature and continuously stirring until the solution is clear, and naturally cooling to form gel. Drying the gel, roasting in two stages and naturally cooling to obtain Pt atom doped Fe 2 O 3 、In 2 O 3 And V 2 O 5 To form the composite powder material. The gas sensor made of the sensitive material provided by the invention can work at a lower temperature and can detect trace formaldehyde and ammonia in the air on site at high sensitivity without being interfered by other common coexisting molecules. |
