• Co (0) are observed because most of the Co nanoparticles are surrounded by the spinel oxide and carbon matrix. The C 1s spectrum shows three peaks (Figure 6D) correlated with several types of C species (C–C at 284.6 eV, C=N/C–O at 286.6 eV, and O–C=O at 289.0 eV) [40], indicating that nitrogen-doped
