| titleOfInvention | Oxygen-doped carbon nitride catalyst, preparation method and application thereof |
| abstract | The invention discloses an oxygen-doped carbon nitride catalyst, a preparation method thereof, and an application in photocatalytic ammonia production. The preparation method includes the steps: (1) calcining melamine to obtain g-C 3 N 4 , which is denoted as BCN; (2) calcining BCN for a second time to obtain g-C 3 N 4 with high specific surface area, which is denoted as HCN; (3) The HCN and the H 2 O 2 solution are mixed uniformly and then placed in a microwave digestion apparatus for constant temperature digestion, and the solid is washed and dried to obtain the oxygen-doped carbon nitride catalyst. In the invention, the specific surface area of the g-C 3 N 4 catalyst is increased by a simple secondary calcination method, and oxygen atoms are doped into the g-C 3 N 4 structure in combination with the microwave hydrothermal method, and the g-C 3 N 4 photocatalyst is The ammonia production performance was greatly improved, reaching 3.98mmol·g -1 ·h -1 , which was 6.22 times that of the unmodified g-C 3 N 4 catalyst. |
