中文摘要:
      采用水热法制备了YBO3微米球。利用XRD、FESEM、TEM、XPS和UV-Vis等对样品的结构、形貌和光学性能进行了表征。在紫外光照射下,采用CHI660E电化学系统研究了样品的电化学性能,并通过罗丹明B的降解反应考察了样品的光催化活性。结果表明:YBO3微米球由纳米片自组装形成;与YBO3微米颗粒相比,YBO3微米球的吸收光谱发生明显红移,在紫外光范围内有较强的吸收;并且YBO3微米球具有较高的光电流和较小的载流子迁移阻力,光催化活性明显提高,40 min对罗丹明B的降解率达到90.9%。
英文摘要:
      A series of YBO3 samples were obtained by hydrothermal method. The microstructures, morphologies and optical properties of the samples were characterized by XRD, SEM, TEM, XPS and UV-Vis. The photocurrent and electrochemical impedance experimental were researched with CHI660E electro-chemical system and the photocatalytic activities of the samples were tested with the photocatalytic degradation of RhB. Results demonstrate that the YBO3 microspheres were self-assembled by nanosheets. Compared with the YBO3 microparticles, redshift phenomenon appears at the absorption edge for YBO-85 with the formation of nanosheets structure. Meantime, the YBO3 microspheres have strong absorption in the ultraviolet range, higher photocurrent and less carrier migration resistance. So, YBO3 microspheres can exhibit a excellent activity to photodegrade RhB under UV light irradiation. The degradation rate of RhB can reach 90.9% under 40 min irradiation time.
