报道了一种以海绵为模板制备金/二氧化铈纳米线三维材料的普适方法,实现了在连续流动体系中对对硝基苯酚的原位连续还原.该催化系统展现了高的反应活性和稳定性.具有高比表面积的二氧化铈纳米线网络不仅能够使金纳米颗粒稳定分散而防止团聚,而且能够增强二氧化铈纳米线网络与金纳米颗粒之间的协同效应,从而带来高的反应活性和稳定性.低成本原材料和高活性及稳定性的催化剂使得三维海绵-金/二氧化铈纳米线网络结构具有应用于工业生产和其他领域中实现连续催化反应的潜力.
A universal method for preparing gold / ceria nanowire three-dimensional materials using sponge as a template was reported, and in situ continuous reduction of p-nitrophenol was achieved in a continuous flow system. The catalytic system exhibited high reactivity And stability. Ceria nanowire networks with high specific surface area not only enable stable dispersion of gold nanoparticles to prevent agglomeration but also enhance the synergistic effect between the network of ceria nanowires and gold nanoparticles, resulting in high The low cost of raw materials and high activity and stability of the catalyst makes the three-dimensional sponge-gold / cerium dioxide nanowire network structure has the potential to be used in industrial production and other fields to achieve continuous catalytic reaction.
