  • 摘要: 通过可见光响应半导体的复合，成功提高了TiO2对芥子气模拟剂2-CEES降解的光催化活性.TiO2在掺杂1wt% LaVO4时可见光催化活性最高，LaVO4/TiO2在24 h后对甲苯的降解率仍然保持在70%以上，对0.24 g·L-1 2-CEES的太阳光催化降解率较商业化TiO2提高20%.
    Abstract: Coupled with visible light absorbing semiconductor, LaVO4 composite materials were prepared and applied successfully to improve the photocatalytic activity of TiO2. It was found that the composite of TiO2 1wt% LaVO4 had the best photocatalytic activity to degrade 70% toluene even after 24 h. The degradation rate of sulfur mustard mimicking agent (2-CEES) on LaVO4/TiO2 increased by 20% from commercial TiO2 under simulated sunlight.
