THE STUDY OF PHOTOCATALYTIC OF Zn^(2+)-DOPED IN TiO_2 NANOPARTICLES IN PHOTOCATALYZING THE DEGRADATION OF RHODAMINE B

用水热法制备了掺杂Zn2+的TiO2纳米粒子,研究了Zn2+离子掺杂的TiO2纳米粒子悬浮液光催化降解罗丹明B的能力.结果表明,Zn2+的掺杂使得TiO2纳米粒子悬浮液光催化降解罗丹明B的能力大大提高,Zn2+离子的掺入量有一最佳值使光催化降解罗丹明B的能力达到最大值.

The Zn2+doped in TiO2 nanoparticles were prepared with hydrothermal method, and the effects on the ability of TiO2 in photocatalyzing degradation of rhodamine B(RB) were studied. The results showed that the doping of Zn2+ in TiO2 nanoparticles made the pheotocatalytics of TiO2 in photocatalyzing the degradation of (RB) enhance, showing a great increase of the rate constant(k) and the initial reaction rate(rini).
