Abstract

A series of N-doped graphene oxide materials were prepared via a simple one-step hydrothermal method using graphene as a raw material, acetonitrile, ethylenediamine, N,N-dimethylformamide as nitrogen sources. Their photocatalytic degradation performance was investigated using Methyl orange (MO) as the model compound. The chemical physical properties were characterized by Fourier transform infrared spectroscopy (FTIR) and ultraviolet spectrophotometry (UV–Vis). The photocatalytic degradation test showed that N-graphene (1 : 40) obtained from N,N-dimethylformamide exhibited the best performance and could be completely degraded within 300 min. The degradation rate still remained above 90% even after three cycles demonstrated N-GO(D) has a good stability. The characterization results confirm that N-doping can stabilize the oxygen functional groups on graphene oxide surface, and also broaden the band gap and expand the photoresponse range of graphene.
