A selective etching approach to pore structure control of polymeric precursors: creating hierarchical porous N, P co-doped carbon nanospheres for semi-solid-state supercapacitors

In this work, utilizing a dynamic imine exchange, we develop a selective etching strategy to construct porous polymer nanosphere precursors, which can be subsequently carbonized into hierarchical porous carbon nanospheres (PCNPs) co-doped with both N and P elements. Our strategy to construct polymer...
