| titleOfInvention | Strontium sodium niobate material and preparation method and application thereof |
| abstract | The invention discloses a strontium sodium niobate material with a molecular formula of Sr 2‑x Na x NbO 4 Wherein x is 0.3-1.4. The preparation method comprises the following steps: (1) mixing 1-3 g of Nb 2 O 5 Adding the mixture into 6-8mol/L NaOH solution, stirring and mixing uniformly, heating to 120-180 ℃, and preserving heat for 2-3 hours to obtain a reaction product; (2) cooling the reaction product to room temperature, cleaning the reaction product, and drying the cleaned reaction product at 40-60 deg.C for 40-60min to obtain precursor Na 2 Nb 2 O 6 A molecular sieve; (3) weighing Na according to the molar ratio of 1 (0.5-2) 2 Nb 2 O 6 Molecular sieves with SrCO 3 Mixing and grinding to obtain mixed powder; (4) heating the mixed powder to 500-600 ℃, presintering for 4-6h, cooling to room temperature, and fully grinding; (5) and (4) heating the mixed powder treated in the step (4) to 600-800 ℃, and calcining for 8-11h to obtain the strontium sodium niobate material. The strontium sodium niobate material has good oxygen adsorption performance and photocatalysis performance, and has good industrial application prospect. |
