Mesoporous core–shell nanostructures with controllable ultra‐large open channels in their nanoshells are of great interest. However, soft template‐directed cooperative assembly to mesoporous nanoshells with highly accessible pores larger than 30 nm, or even above 50 nm into macroporous range, remains a significant challenge. Herein we report a general approach for precisely tailored coating of hierarchically macro‐/mesoporous polymer and carbon shells, possessing highly accessible radial channels with extremely wide pore size distribution from ca. 10 nm to ca. 200 nm, on diverse functional materials. This strategy creates opportunities to tailor the interfacial assembly of irregular mesostructured nanounits on core materials and generate various core–shell nanomaterials with controllable pore architectures. The obtained Fe,N‐doped macro‐/mesoporous carbon nanoshells show enhanced electrochemical performance for the oxygen reduction reaction in alkaline condition.

从不规则介孔结构的纳米单元的界面组装大/中孔纳米壳的一般形成。

介孔核-壳纳米结构在其纳米壳中具有可控的超大开放通道，引起了人们的极大兴趣。然而，软模板定向的协同组装到具有高度可及的孔（大于30 nm，甚至大于50 nm到大孔范围）的中孔纳米壳仍然是一个巨大的挑战。在这里，我们报告了一种精确定制的分层宏观/中微孔聚合物和碳壳涂层的通用方法，该方法具有高度可及的径向通道，并且孔径分布范围从ca到ca。10 nm至大约 200 nm，在各种功能材料上。这种策略创造了机会，可以在核心材料上定制不规则介孔纳米单元的界面组装，并生成具有可控孔结构的各种核壳纳米材料。得到的铁
