含钛高炉渣作为一种光催化材料其量子利用率以及对太阳能的利用率都很低,考虑到稀土元素由于其特殊的电子结构在形成氧化物时具有良好的半导体特性,其金属氧化物的掺杂能在一定程度上改良含钛高炉渣的光催化性能的特点,将掺杂稀土氧化物的含钛高炉渣用于紫外线照射条件下亚甲基蓝溶液的降解试验中,并通过射线衍射(XRD)、扫描电子显微镜(SEM)等分析手段检测寻找最佳稀土元素掺杂量。试验结果表明:稀土元素CeO2,Y2O3的最佳掺杂量分别为0.5%、1.0%,此时其对亚甲基蓝的降解率分别达到72.2%、74.0%。
Titanium-containing blast furnace slag as a photocatalytic material its quantum efficiency and utilization of solar energy are very low, taking into account the rare earth elements due to its special electronic structure in the formation of oxides have good semiconductor properties, the metal oxide Doping can improve the photocatalytic performance of titanium-containing blast furnace slag to some extent. The rare-earth oxide-containing titanium-containing blast furnace slag is used in the degradation of methylene blue solution under UV irradiation. The effects of XRD, , Scanning electron microscopy (SEM) and other analytical means to detect the best amount of rare earth elements doping. The results show that the optimal doping amount of CeO2 and Y2O3 are 0.5% and 1.0%, respectively. At this time, the degradation rate of methylene blue reaches 72.2% and 74.0% respectively.
