Raman spectroscopyThe features of the Raman spectra of Co3O4 30‐nm nanoparticles depend strongly on their agglomeration state. When measured at low incident laser power, the spectrum of isolated nanoparticles corresponds to that found in bulk materials, whereas the agglomerated nanoparticles present a...

Fig. 15 depicts the Raman spectra of the graphite and the prepared GOs samples. Raman spectroscopy is widely used to gain insight into the structural information of carbon-based materials [[63], [64], [65], [66]]. The presence of CC bonds and conjugation leads to high Raman intensities....
1, the fabrication of NiMoSe/NF-2 was achieved through three sequential steps. Initially, (NH4)6Mo7O24•4H2O and Ni(NO3)2•6H2O were respectively, used as Mo and Ni sources to obtain the precursor of NiMoO4. The NiMoSe/NF-1 was then synthesized by calcining the NiMoO4 with S...
