Herein, small Co nanoparticles (NPs) encapsulated in N-doped double-shelled carbon nanocages grafted with thin carbon nanotubes (Co@CNTs@DSCNCs) were synthesized from yolk-shell bimetallic zeolitic imidazolate framework (BMZIF). For HER electrocatalysis, they exhibit higher activity (η = 214 mV) and more favorable kinetics than Co@CNTs@PC (PC = porous carbon) with thick CNTs and large Co NPs derived from solid BMZIF cubes.
在此，通过蛋黄壳双金属沸石咪唑酯骨架（BMZIF）合成了包裹在接枝有细碳纳米管的N掺杂双壳碳纳米笼中的小钴纳米颗粒（NPs）（Co@CNTs@DSCNCs）。对于析氢电催化，它们表现出比由实心BMZIF立方体衍生的具有厚碳纳米管和大钴纳米颗粒的Co@CNTs@PC（PC = 多孔碳）更高的活性（η = 214 mV）和更有利的动力学。
