Abstract
A facile strategy to fabricate Co/Co<sub>9</sub>S<sub>8</sub> nanoparticles-encapsulated in carbon nanotubes, on an N-doped porous graphene sheet (Co/Co<sub>9</sub>S<sub>8</sub>@CNTs) <italic>via</italic> pyrolysis of a mixture of Co(NO<sub>3</sub>)<sub>2</sub>, melamine and <sc>l</sc>-cysteine is reported.
