摘要: 对氨基苯酚在医药和显影等领域有重要应用，利用催化还原法将废水中的毒性较高的对硝基苯酚(4-NP)转换为对氨基苯酚(4-AP)具有重要意义。本文利用超长一维结构的铁酸铋纳米纤维(BiFeO3 NFs)为载体，采用原位还原法负载Ag纳米粒子，其负载量约为2.27%。实验表明，BiFeO3/Ag NFs在8 min内催化4-NP还原为4-AP，其转化率为98.3%。根据反应动力学曲线获得BiFeO3/Ag NFs的动力学速率常数kapp为0.295 min−1。这种优异的性能这是由于Ag具有更高的功函数，能够与BiFeO3形成异质结构，有效促进界面电子快速转移到半导体BiFeO3，有效提高了催化剂的催化活性。此外，BiFeO3 NFs的特殊结构也使其具有良好的循环稳定性，制备的复合催化剂在3次循环使用后经过8 min对4-NP的还原率依然可以达到96.7%，这种循环使用性能良好且性能优异的一维结构催化剂有望在有机染料等污染物处理等领域表现出优异的潜力。
Abstract: It is of great significance to convert highly toxic p-nitrophenol (4-NP) in wastewater into p-aminophenol (4-AP) via the reduction method. In this study, ultra-long one-dimensional bismuth ferrite nanofibers (BiFeO3 NFs) were used as the support, and Ag nanoparticles were loaded by the in-situ reduction method with a loading capacity of approximately 2.27%. Experimental results show that BiFeO3/Ag NFs can catalyze the reduction of 4-NP to 4-AP within 8 minutes, achieving a conversion rate of 98.3%. The apparent kinetic rate constant (kapp) of BiFeO3/Ag NFs obtained from the reaction kinetic curve is 0.295 min−1. This excellent performance is attributed to the higher work function of Ag, which can form a heterostructure with BiFeO3, effectively promoting the rapid transfer of interfacial electrons to the semiconductor BiFeO3 and thus significantly enhancing the catalytic activity of the catalyst. In addition, the special structure of BiFeO3 NFs endows it with good cyclic stability. After 3 cycles of use, the prepared composite catalyst still maintains a reduction rate of 96.7% for 4-NP within 8 minutes. This one-dimensional structured catalyst with excellent performance and good reusability is expected to exhibit great potential in the treatment of organic dyes and other pollutants.
