中文摘要:
      铁酸铋是一种钙钛矿型半导体光催化剂,因具有合适的光学带隙,良好的化学稳定性及可见光吸收性等特点而备受青睐。然而,铁酸铋的光生电子空穴对复合率高,载流子效率较低,导致其光催化活性较弱,限制了其实际应用。在概述铁酸铋结构和光催化机理的基础上,着重综述了贵金属沉积、半导体复合、金属离子掺杂等铁酸铋改性方法的作用机理与研究进展,探讨了铁酸铋光催化剂未来的研究方向。
英文摘要:
      Bismuth ferrite is a perovskite-type semiconductor photocatalyst, which is favored due to its proper optical band gap, good chemical stability and visible light absorption. However, the photogenerated electron-hole pair recombination rate of bismuth ferrite is high, and the carrier efficiency is low, which leads to the weakening of photocatalytic activity and limits its practical application. In this paper, based on the overview of the structure and photocatalytic mechanism of bismuth ferrite,the mechanism and research progress of bismuth ferrite modification methods such as precious metal deposition, semiconductor compounding, and metal ion doping are emphaticallyreviewed, and the future research directions of bismuth ferrite photocatalysts are discussed.
