Raman spectra were performed by using a Witec/alpha 300R confocal microscope with a 532-nm laser at atmospheric conditions. The XPS was performed using a PHI 5000 X-ray photoelectron spectrometer equipped with a monochromatic using Al Kα radiation (hν=1486.6 eV), and the peaks were ...
This is consistent with the results of Raman spectra (Figure 2b). As can be seen, all the MoxC@N-C display two typical carbon peaks located at 1351 cm-1 (D band) and 1594 cm-1 (G band), which are attrib- uted to the crystal defect or disordered graphite, and graphitic lattice ...
