在水热自组装石墨烯结构的基础上，采用纳米粒子诱导蚀刻的方法，首次成功制备了具有分层孔排列的合理设计的石墨烯纳米网组装泡沫（GMF）。新开发的GMF为开发高性能功能器件提供了新的材料平台。特别是，N- s共掺杂的GMF电极对氧还原反应（ORR）表现出优异的电催化活性，优于以往报道的大多数石墨烯基ORR催化剂。
Rationally designed graphene nanomesh assembled foam (GMF) with hierarchical pore arrangement has been successfully fabricated for the first time by a site-localized nanoparticle-induced etching strategy on the basis of hydrothermally self-assembled graphene architecture. The newly developed GMF provides a new material platform for developing high-performance functional devices. Specially, the N- and S-codoped GMF electrode exhibits excellent electrocatalytic activities for oxygen reduction reaction (ORR), better than most of the graphene-based ORR catalysts reported previously.
