ZnO磁性纳米材料的制备以及光催化性能的研究
|
摘要
用一个简单的方法将Fe与ZnO掺杂,并研究了它的光催化性能。通过球磨机制备出高效率降解甲基橙的光催化剂,一部分归因于ZnO掺杂了Fe,一部分则是由于在高速研磨下样品颗粒尺寸变小,氧化锌纳米颗粒的反应速度约为普通氧化锌颗粒100~1000倍,尺寸越小光催化效果越明显[1]。而且通过球磨机掺杂制备的光催化剂可以循环使用。
Fe doped ZnO were prepared by a simple method, and studied the photocatalytic properties.Through the simple ball mill grinding, the elemental of Fe doping ZnO catalysts showed the higher degradation rates than that of pure ZnO,which was attributed to the Fe doping effects and due to the ball mill grinding, the particle size of the samples become smaller. The reaction speed of ZnO nanoparticles is about 100~1000 times of the normal ZnO particles, the size become smaller the effect of the light catalytic become more obvious[1]. And the photocatalyst can be recycled by doping with the ball mill.
