| 英文摘要 | SrTiO(3)particles with different morphologies can be produced by hydrothermal reaction route using P25 TiO2, Sr(OH)(2)center dot 8H(2)O, NaOH, and mineral acid as the starting materials in the presence of dilute nitric acid solution and heated at 220 degrees C for 24 h. The dilute nitric acid was replaced by the dilute hydrochloric acid or dilute sulphuric acid, and the reaction time was fine adjusted, and this eventually lead to the formation of nanoparticles or mixing of cubes and nanoparticles. Pure SrTiO(3)can be obtained by changing the mineral acid to nitric acid or hydrochloric acid and adjusting the reaction time from 24 to 40 h. The mineral acid in the synthetic parameter was changed to sulfuric acid, and the synthesized SrTIO(3)sample contained SrSO(4)impurities. The electrochemical investigations confirmed that the performance of SrTiO(3)rhombus particles in terms of rate capability was significantly higher as compared to the SrTiO(3)nanoparticles or mixing of cubes and nanoparticles. Photocatalytic activity test indicated that the SrTiO(3)rhombus particles exhibited an exceptional photocatalytic activity for the removal of congo red dye under simulated sunlight irradiation than that of other SrTiO(3)samples. The variation tendency of photocatalytic activity for different SrTiO(3)samples can be ascribed to the synergistic effects of impurity concentration, energy band, adsorbed oxygen concentration, optical absorption coefficient, charge carrier utilization and separation efficiency, and crystal surface exposure. |
