| titleOfInvention | Preparation method and application of SrTiO3/Cu2O heterojunction composite nano material |
| abstract | Novel SrTiO 3 /Cu 2 The preparation method of the O-junction composite nano material comprises the following steps: dissolving (tetra) isopropyl titanate and strontium chloride hexahydrate in acid respectively, mixing, adjusting the pH value to 3-4, heating to 90 ℃, and preserving heat for 3 hours; then heating to 400-500 ℃, and preserving heat for 4-6 hours; obtaining SrTiO 3 A catalyst; stirring and dissolving copper acetate dihydrate in glycol monomethyl ether at 35 ℃, stirring, performing ultrasonic treatment for 60 minutes, and then adding SrTiO 3 Stirring a catalyst, adding a sodium hydroxide solution, adjusting the pH value to 10-14, and stirring for 10 minutes at 50 ℃; adding sufficient glucose solution, and reacting for 1-1.5 hours; cooling to room temperature, and performing centrifugal separation to obtain a precipitate solid. SrTiO of the invention 3 /Cu 2 SrTiO in O heterogeneous composite catalyst 3 And Cu 2 The heterojunction is formed by O, the application of the electron and the hole is facilitated, the heterojunction catalyst degrades organic dye wastewater under visible light, and particularly the photocatalytic degradation efficiency of methylene blue organic solution reaches 92%. |
