一步法制备Fe掺杂ZnWO4光催化剂及其固氮性能
One-step fabrication of Fe-doping ZnWO4 photocatalyst and its nitrogen fixation performance
摘要
Abstract
Fe-doped ZnWO4(Fe-ZWO)photocatalysts with flower ball structure were synthesized by one-step solvothermal method.The catalysts were characterized by XRD,SEM,DRS and electrochemistry.The photocatalytic activity of Fe-ZnWO4 samples was determined by Nessler's reagent method with aerating nitrogen gas during the experiment.The results showed that the band gap of ZnWO4 was narrowed,the separation efficiency of its photogenerated carriers was improved and the nitrogen fixation performance of the photocatalyst was effectively enhanced doping with Fe ions.5％Fe-ZnWO4 sample obtained the highest photocatalytic nitrogen fixation activity with the molar ratio of doped Fe ions to ZnWO4 of 0.05∶1.The rate of nitrogen fixation could reach 140.91 μmol/(g·h)after 2 h of light irradiation,which was 8.9 times higher than that of ZnWO4.After three cyclic tests,the 5％Fe-ZnWO4 sample remain good photocatalytic nitrogen fixation activity.关键词
