| titleOfInvention | A kind of preparation method of ultrasensitive room temperature hydrogen sensor |
| abstract | The invention discloses a preparation method of an ultra-sensitive room temperature hydrogen sensor. The method firstly takes DNA, deionized water, 2-[(2-aminoethyl)amino]ethanesulfonic acid sodium salt and acetic acid, mixes and stirs magnetically for 2 hours, Obtain a homogeneous solution A; get the graphene oxide aqueous solution and add one of palladium dichloride, hexahydrate nickel nitrate or hexahydrate cobalt nitrate and graphene oxide to deionized water, and ultrasonically make the palladium dichloride all dissolve, The obtained clear solution was added to solution B, and hydrazine was added, and the magnetic stirring was continued to make the solution evenly mixed; the obtained mixed solution was poured into the reactor for hydrothermal reaction, and then the hydrothermal reaction product was washed with deionized water The washed reaction product is rapidly frozen with liquid nitrogen, put into freeze-drying equipment for freeze-drying, and finally the gas-sensitive material; the hydrogen sensor of the present invention does not require any heating, can work directly at room temperature, and the detected hydrogen concentration can be as low as 50ppb, and Response time is short. |
