| titleOfInvention | Nitrogen-silver doped nano TiO2Method for preparing powder |
| abstract | Nitrogen-silver doped nano TiO 2 A preparation method of powder, belonging to the field of materials. The method comprises the following steps: adding silver nitrate into ethanol, and stirring to obtain a mixed solution A; dropwise adding tetramethylammonium hydroxide to the mixed solution A under stirring, and continuously stirring to obtain a mixed solution B; dropwise adding isopropyl titanate into the mixed solution B under stirring, and continuously stirring to obtain sol; immersing a copper plate at the bottom of the sol, aging for 10-12 h, drying at 60-80 ℃ for 20-22 h to obtain the copper plate with the surface covered with colloid, introducing 500-600A direct current for 15-25 min to obtain sintered colloid attached to the copper plate, scraping, and grinding to obtain the nitrogen-silver doped nano TiO 2 And (3) pulverizing. The method has the advantages of simple synthesis process, mild reaction conditions, greatly shortened sample sintering time, better sintered shape, more stable structure, greatly reduced production cost, good repeatability and capability of preparing the nitrogen-silver doped TiO 2 The degradation rate of the photocatalyst to methylene blue is obviously improved. |
