A new way for synthesizing porous composite with cobalt species and N-doped carbon nanotubes (NDCNTs) was reported here by using cobalt salts and melamine mixtures as precursor. The Co(O)x/NDCNTs exhibited good activity of electrocatalytic O2 production. Furthermore, after reduced by H2, the Co–NDCNTs showed strong absorption of visible light and high catalytic activity of H2 production, which is 598.5 μmol g−1 h−1 under the visible light (λ > 420 nm). The results suggested that supramolecular preorganization of melamine monomers may be a promising method of synthesizing two-dimensional N-doped carbon nanotube with Co particles in it. The morphologies should be beneficial for the charge transport and separation. This work can encourage further synthesize new efficient noble-metal-free photocatalysts or electrocatalysts.
