此处,我们报导万用的策略制作 -Au/ceria nanowire (NW ) 联网在一个连续流动系统在 situ 认识到 p-nitrophenol 的连续减小的三维的三聚氰胺海绵(MS ) 。这个系统证明了是高活动和稳定性。有大表面区域的 ceria NW 网络能稳定在 ceria NW 上驱散的微小的 Au nanoparticles,它被 dip-coating 在 MS 的框架上装载,并且提高在 ceria NW 网络和 Au nanoparticles 之间的 synergistic 效果,导致为催化申请的极其高的活动和好稳定性。有高活动和稳定性的便宜原料和催化剂可以使这三维的 MS-Au/ceria 成为在工业或另外的地为连续催化反应申请答应的 NW 合成材料。
英文摘要:
Herein, we report a versatile strategy to fabri- cate three-dimensional melamine sponge (MS)-Au/ceria nanowire (NW) networks to realize in situ continuous reduction of p-nitrophenol in a consecutive flow system. This system has proven to be high activity and stability. The ceria NW networks with large surface area can stabi- lize tiny Au nanoparticles dispersed on the ceria NWs, which are loaded on the framework of MS by dip-coating, and enhance the synergistic effect between ceria NWs networks and Au nanoparticles, leading to extremely high activity and good stability for catalytic application. The low-cost raw materials and catalyst with high activity and stability may make this three-dimensional MS-Au/ceria NWs composite material promising for continuous cat- alytic reaction application in industry or other fields.
