摘　　要：硝基苯酚是工业和农业废水中常见的有机污染物之一。近年来,由于纳米金催化材料的优异催化性能,纳米金催化材料日益成为催化还原对硝基苯酚的一种高效、快速和环境友好的催化材料;合成高度分散、尺寸均一、稳定、易分离及可重复使用的纳米金催化材料是该领域的研究重点。本文以纳米金催化材料的整体结构为主线,归纳了纳米金催化材料的最新研究进展;重点讨论了纳米金催化材料的制备手段及其催化活性、稳定性、可回收性和可重复使用性;并对纳米金催化材料的发展方向和今后需解决的关键问题进行了展望。Nitrophenols are one of the most common organic pollutants in industrial and agricultural wastewater. In recent years, due to the excellent catalytic properties of nano-Au catalytic materials, as highly efficient, fast and eco-friendly catalysts, nano-Au catalytic materials have been widely applied to the reduction of 4- nitrophenol. Correspondingly, synthesis of highly dispersed, size controllable, long-term and recycleable nano- Au catalytic materials is the main stream of this field. Based on the overall structure of the nano-Au catalytic materials, this review summarizes the latest progress on this direction, especially for the preparative methods, catalytic performance, stability, recyclability and reusability. Finally, the remaining problems and the future developing prospects are also proposed.
