Facile hydrothermal synthesis of nanocomposites of nitrogen doped graphene with metal molybdates (NG-MMoO4) (M=Mn, Co, and Ni) for enhanced photodegradation of methylene blue

A facile one-pot hydrothermal synthesis of nanocomposites of nitrogen doped graphene with MnMoO4/CoMoO4/NiMoO4 is reported. The morphological and structural characteristics of prepared NG-MMoO4 nanocomposites have been characterized by Powder X-ray diffraction, Fourier transform vibrational spectroscopy, Scanning electron microscopy, Transmission electron microscopy and Thermal analysis. The molybdates are well-anchored and uniformly distributed on the surface of nitrogen doped graphene sheets. The nanocomposites exhibit excellent photocatalytic activity as demonstrated by photodegradation of methylene blue under Ultraviolet–Visible irradiation by using NG-MnMoO4 as catalyst.
