Design and synthesis of dodecahedral carbon nanocages incorporated with Fe3O4

Dodecahedral carbon nanocages modified with Fe₃O₄ NPs (Fe₃O₄/C NCs) were constructed using ZIF-8 as template and polydopamine as carbon source. The NCs display controllable feature structures with Fe₃O₄ NPs homogenously distributed, which enriched the function of the C NCs.
