| 摘 要： | 通过溶胶—凝胶法制备掺杂Co2+的纳米TiO2,并用XRD和TEM进行了分析和表征.以汞灯为光源,通过对罗丹明B的降解反应,考察了Co2+/TiO2的光催化活性.结果表明,Co2+的掺杂减小了TiO2颗粒的粒径,提高了TiO2的光催化活性,Co2+惨杂量为1.0%时的光催化活性最高.另外,本文还研究了催化剂投加量对罗丹明B光催化降解效率的影响.

| Abstract: | Co~(2 )-doped TiO_2 nanoparticles were prepared by sol-gel method and characterized by means of X-ray diffraction(XRD) and transmission electron microscopy(TEM).The activity of the prepared photocatalysts was investigated by degradation reaction of Rhodamine B radiated with mercury vapor lamp.Effects of amounts of TiO_2 and irradiation time on photocatalytic activity were also investigated.The results showed that the photocatalytic activity of Co~(2 )-doped TiO_2 was much higher than that of pure TiO_2 particles.The optimum value of the Co~(2 )/TiO_2 was 1.0% for the photocatalytic degradation of Rhodamine B. |
