通过水热法合成了不同浓度Er3+掺杂Zn WO4纳米棒,并通过XRD、TEM和DRS等对其进行了表征。通过在模拟太阳光照射下光降解Rh B的速度来检测Zn WO4样品的光催化活性,研究了Er3+掺杂浓度对Zn WO4催化活性的影响。实验结果表明,当Er3+掺杂浓度为2mol%时,其光催化性能最好,因为引进Er3+后,Er3+加快了电荷分离效率。
Different concentrations of Er3 + doped Zn WO4 nanorods were synthesized by hydrothermal method and characterized by XRD, TEM and DRS. The photocatalytic activity of Zn WO 4 was detected by photodegrading Rh B under simulated solar irradiation and the effect of Er 3+ doping concentration on the catalytic activity of Zn WO 4 was investigated. The experimental results show that when Er3 + doping concentration is 2mol%, the photocatalytic performance is the best, because the introduction of Er3 +, Er3 + to speed up the charge separation efficiency.
