| titleOfInvention | A preparation process and system of high pyridine nitrogen doped activated carbon |
| abstract | The invention relates to the technical field of nitrogen-doped activated carbon, in particular to a preparation process and system for high-pyridine nitrogen-doped activated carbon. The preparation process is to dope carbon materials with polyvinylpyridine as a nitrogen source under heating conditions to obtain high-pyridine nitrogen-doped activated carbon, including the following steps: 1) Preparation of polyvinylpyridine, which is recorded as ppl‑1 ; 2) Preparation of carbonized precursor, the carbonized precursor is recorded as yk-1; 3) Preparation of high pyridine nitrogen doped activated carbon: KOH, ppl-1 and yk-1 are mixed, and under N 2 atmosphere, the mixture is used The temperature was programmed to activate, and the activated sample was thoroughly washed several times with hydrochloric acid to remove inorganic salts, then washed with distilled water until the pH was neutral, and finally dried to obtain high pyridine nitrogen activated carbon. In the present invention, by replacing traditional nitrogen sources such as ammonia gas, ammonia water, melamine or G - C3N4 with polyvinylpyridine synthesized from vinylpyridine, nitrogen - doped activated carbon with a higher proportion of pyridine nitrogen functional groups can be obtained, and The cost is lower. |
