The present investigation focused on the photocatalytic degradation of acetamiprid in aqueous solutions under visible light over bare ZnO as well as N- and N-GO-doped photocatalysts. The synthesised materials were characterised using SEM, TEM, XRD, nitrogen sorption, photoluminescence, UV-Vis, FTIR and electrochemical impedance spectroscopy techniques. The obtained results pointed out the high photocatalytic performances of the N-GO-ZnO allowing complete degradation of the acetamiprid after 5 hours of reaction at ambient temperature. Under otherwise the same operating conditions, 12, 38 and 68% conversion were reached in the absence of any photocatalyst, over the bare ZnO and N-doped ZnO materials, respectively.
本研究聚焦于在可见光下，以裸露的ZnO以及氮掺杂和氮-氧化石墨烯（N-GO）掺杂的光催化剂对水溶液中啶虫脒的光催化降解。使用扫描电子显微镜（SEM）、透射电子显微镜（TEM）、X射线衍射（XRD）、氮吸附、光致发光、紫外-可见光谱（UV-Vis）、傅里叶变换红外光谱（FTIR）和电化学阻抗谱技术对合成材料进行了表征。所得结果表明，N-GO-ZnO具有高光催化性能，在室温下反应5小时后可使啶虫脒完全降解。在其他相同操作条件下，在无任何光催化剂、裸露的ZnO和氮掺杂ZnO材料上，转化率分别达到了12%、38%和68%。
