中文摘要：

通过NH3等离子体后处理引入N使其进入到ZnO晶格中,制备出了N掺杂的纳米ZnO光催化剂。通过测试,研究了该样品的结构性质、表面形貌和在不同催化剂浓度、不同反应物浓度、氧气等条件下光催化降解甲基橙的降解效率。分析结果表明,N的掺杂提高了光催化剂的光催化效率。

英文摘要：

The nano-ZnO was grown by electrochemical deposition method. In order to introduce N,the NH3plasma post treatment was used. X-ray diffraction spectroscopy analyses indicate that N doping can not disturb the structure of ZnO. No additional peaks are observed in the sample.X-ray photoelectron spectroscopy analyses also indicate that N atoms permeate into the ZnO lattice and replace the O sites without changing the wurtzite structure. N doping enhances the separation efficiency of the photogenerated electron and hole,thereby improving the catalytic efficiency of the photocatalyst.
