以高度有序的二氧化钛纳米管阵列为光阳极,研究了其对水中氨氮的光电催化去除。结果表明,二氧化钛纳米管阳极对总氨氮(TAN)的去除效率与施加的偏压密切相关。即使不调节pH,在偏置电位为1.0V的120min内,TAN(初始浓度为0.145 mM)的脱除率也超过99%。值得注意的是,TAN可以直接氧化成N2和NO3−-N,而不会积累NO2−-N的中间产物。同时,化学清除剂的存在揭示了光生空穴是TAN氧化的主要氧化物种。这项工作突出了光电催化在水溶液脱氨领域的潜在应用。
The photoelectrocatalytic removal of ammonia in water was investigated using highly ordered TiO2nanotube arrays as a photoanode. The results showed that the removal efficiency of total ammonia nitrogen (TAN) was closely related to the bias potential applied on TiO2nanotube photoanode. Even without an adjustment of pH, over 99% of TAN (initial concentration 0.145 mM) was removed in 120 min with a bias potential of 1.0 V. It is important to note that the TAN could be directly oxidized into N2and NO3−-N without accumulation of an intermediate product of NO2−-N. Meanwhile, the presence of the chemical scavengers revealed that photogenerated holes were the main oxidative species for the TAN oxidation. This work highlights the potential application of photoelectrocatalysis in the field of aqueous ammonia elimination.
