采用热分解方法制备了4种电极钛基金属氧化物:Ti/Sn O2+Sb2O3、Ti/Sn O2+Sb2O3/Sn O2+Ir O2、Ti/Sn O2+Sb2O3/Sn O2+Ru O2和Ti/Sn O2+Sb2O3/Sn O2+Ce O2.X-射线衍射分析表明Ti/Sn O2+Sb2O3/Sn O2+Ce O2电极的Ce O2晶体结构完好,连续工作较长时间电极表面没有明显析氧.使用该电极电解氧化氨氮模拟废水(降解2 h),氨氮模拟废水从高浓度(500 mg·L-1)降解为较低浓度(180 mg·L-1),降解效率可达64%,电解活性最佳.
Four kinds of Ti-based metal oxides were prepared by thermal decomposition method: Ti / Sn O2 + Sb2O3, Ti / Sn O2 + Sb2O3 / Sn O2 + Ir O2, Ti / Sn O2 + Sb2O3 / Sn O2 + Ru O2 and Ti / SnO2 + Sb2O3 / SnO2 + CeO2.X-ray diffraction analysis showed that the CeO2 crystal structure of Ti / SnO2 + Sb2O3 / SnO2 + CeO2 electrode is intact and there is no obvious oxygen evolution on the surface of electrode for long time The electrode was used for the electrochemical oxidation of ammonia-simulated wastewater (2 h), and the ammonia-nitrogen simulated wastewater was degraded from high concentration (500 mg · L-1) to lower concentration (180 mg · L-1) optimal.
