氨氧化反应(AOR)是一种环境友好的电化学制氢技术。目前，开发低成本、高性能、坚固耐用的AOR催化剂是提高氨电解槽整体效率的关键。在这里，我们报道了一种新型的独立的三维(3D)多孔掺氮石墨烯气凝胶(NGA)的合成和表征，作为一种高性能和坚固的AEC制氢的电催化剂。在纯水溶剂中，以氧化石墨烯(GO)和聚氧丙烯二胺D400为前驱体，通过自组装工艺制备了具有三维随机排列的多孔骨架结构的NGA基片。然后，通过简单的电沉积方法将铂纳米簇状结构均匀分散并嵌入到NGA上。所制备的铂/非金属氧化物整体式材料具有较高的氨电氧化活性。
Ammonia oxidation reaction (AOR) is an environmentally friendly electrochemical technology for hydrogen production. Nowadays, exploiting low-costing, high-performance and robust catalysts for AOR is essential to improve the overall efficiency of ammonia electrolysis cell (AEC). Here, we report the synthesis and characterization of a novel free-standing three-dimensional (3D) porous N-doped graphene aerogel (NGA) anchored with Pt nanocluster (Pt/NGA) monolithic material as a high-performance and robust electrocatalyst for hydrogen production from AEC. The NGA substrate was facilely fabricated through a self-assemble process into the randomly arranged 3D porous backbone structure with graphene oxide (GO) and poly(oxypropylene)diamine D400 as precursors in a pure water solvent. Then, the Pt nanocluster-like structures were uniformly dispersed and embedded onto NGA through the simple electrodeposition method. The as-prepared Pt/NGA monolithic materials exhibited a higher ammonia electro-oxidation activity wit...
