| titleOfInvention | A method for preparing magnetic titanium nanomaterials from agricultural straws |
| abstract | The invention belongs to the technical field of functional materials, and provides a method for preparing magnetic titanium nanomaterials by using agricultural straws, which comprises the following steps: S1, using crop straws as raw materials to prepare biochar; S2, preparing Fe by wet chemical co-precipitation method 3 + -NH sol; S3, adding the biochar obtained in step S1 and the titanium source to the Fe 3 + -NH sol obtained in step S2, performing ultrasonic stirring and centrifugal separation successively, and using the solid obtained by separation Ionized water is washed to neutrality, then rotary evaporation is performed to form a solid paste, then dried, and finally ground to obtain magnetic titanium nanomaterials. In step S1, the crop stalks are corn stalks, and the stalk leaves are retained; the corn stalks with the retained leaves are pulverized and ground through an 80-mesh sieve, and then carbonized by the oxygen-limited temperature control method, wherein the carbonization temperature is 300°C, 500°C, One of the 700 ℃, carbonization time 2h, to obtain biochar. |
