In this study, we synthesized uniform Au nanoparticles (NPs) within the pore channels of Fe3C@NG via a simple chemical method. The resulting Fe3C/Au@NG composite catalyst was characterized, and its catalytic performance in the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) in aqueous solution under mild conditions was studied. Field emission transmission electron micrograph results revealed uniformly distributed Au NPs inside the pore channels of Fe3C/Au@NG, and this composite catalyst exhibited excellent catalytic performance and good reusability for 4-NP reduction and is easy to synthesize. Therefore, magnetically recoverable Fe3C/Au@NG appears to be a promising catalyst for the reduction of 4-nitrophenol.

高效且可回收的Fe3C / Au @ NG催化剂,用于还原4-硝基苯酚

在这项研究中,我们通过一种简单的化学方法在Fe 3 C @ NG的孔道内合成了均匀的金纳米颗粒(NPs)。对所得的Fe 3 C / Au @ NG复合催化剂进行了表征,研究了其在温和条件下将4-硝基苯酚(4-NP)还原为4-氨基苯酚(4-AP)的催化性能。场发射透射电子显微照片结果表明,Fe 3 C / Au @ NG孔道内部的Au NPs分布均匀,该复合催化剂表现出优异的催化性能和对4-NP还原的可重复使用性,并且易于合成。因此,可磁回收的Fe 3 C / Au @ NG似乎是还原4-硝基苯酚的有前途的催化剂。
