| titleOfInvention | A kind of preparation method and application of porous hexagonal boron nitride with high specific surface area |
| abstract | The invention relates to a preparation method of porous hexagonal boron nitride with high specific surface area, comprising the following steps: (1) adding 50% ethanol aqueous solution after mixing boric acid, melamine and sodium dodecylsulfuric acid, heating, cooling, washing with water, Dry to obtain the dried floc; (2) Add ammonium sulfate to the dried floc after grinding to obtain a mixed powder; (3) Put the mixed powder into an alumina crucible and put it into a tubular furnace; Vacuumize the tube furnace cavity; (5) pass high-purity nitrogen into the tube furnace cavity; (6) carry out high-temperature calcination, first heat from 50°C to 300°C, and keep it for 1h; then heat it to 1100°C, keep it for 2h; then heat it to 1460°C , keep it warm for 4 hours, and take it out after the temperature in the tube furnace cavity is cooled to room temperature, that is, porous hexagonal boron nitride. The invention also discloses the application of the porous hexagonal boron nitride. The preparation process of the invention is simple, and the obtained product has a high specific surface area, and can be applied in many fields such as air pollution, water pollution, catalytic reaction and the like. |
