| 摘要 | The size, morphology, and structure of a Bi nanoparticle can significantly affect its photocatalytic performance. In this study, core shell structured Bi@amorphous Bi2O3 nanospheres were synthesized through a one-step solvothermal method, and the reaction mechanisms on NO removal were proposed. It was found that Bi nanoparticles can generate charge carriers by surface plasma resonance (SPR) under visible light irradiation, while the surface amorphous Bi2O3 layer can facilitate the charge carriers' separation. The Bi@ Bi2O3 sample with the synthesis time of 18 h exhibited superior visible light photocatalytic activity for NO degradation, attributed to the suited size and suitable amorphous Bi2O3 layer. O-center dot(2)-, O-1(2), and (OH)-O-center dot radicals were identified as the main reactive species involved in the photocatalysis processes. Moreover;the enhancement mechanisms of photocatalytic NO removal over Bi@Bi2O3 samples were discussed. This study demonstrated that the fabrication of core shell structured Bi@Bi2O3 is a good strategy for effective air pollution control. |
