摘 要: 本文通过对稀土氧化镧不同掺杂量,不同锻烧温度的样品光催化活性的研究显示,适量的稀土氧化镧掺杂有利于提高TiO_2的光催化活性;而关于稀土镧提高TiO_2光催化活性的机理有异于有关报道。 The effect of La2O3 content and calcinating temperature on the photocatalytic activity of La2O3 doping TiO2 was investigated in this paper.The study showed that the addition of appropriate amount of La2O3 is effective for improving the photocatalytic activity of TiO2, but its mechanism wasn' t as the same as some report.
