摘要: Graphical abstract: Cobalt nanoparticles were prepared by a reduction process inside polymer pores. A porous network (polystyrene) was chosen as the template for synthesis of elementary cobalt high surface area are prone to oxidation. The preliminary studies reveal that is first formed with an oxide protective layer outside and upon repeating cycles, inner pores polymers opened which enhanced yield metallic cobalt. These embedded in ideal carbon nanotubes can act catalyst nanotube synthesis. concentration be tuned this technique cycling process. Highlights: {yields} Elementary synthesized polystyrene novel self protection achieved auto-shelling metal oxide. magnetisation coercivity could cycles.
