AbstractLead(II) is a highly toxic upon accumulation in the human body and a thorough cleanup of this pollutant in water resources has become a rising worldwide concern. In this study, multi-functional nitrogen-doped carbon-MoS2 (NC-MoS2) nanohybrid composite was successfully synthesized by a step-by-step approach and applied as an effective heavy metal ions adsorbent. Scanning electron microscopy and energy dispersive X-ray spectrometer analysis presents multilayer irregular nanosheets and reveals the uniform distribution of C, N and O elements in the fabricated nanomaterials, respectively. Powder X-ray diffraction, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy confirm the functionalization of oxygen-containing functional groups arising from the nitrogen-doped carbon. Particularly, the NC-MoS2 possesses an excellent adsorption capacity (439.09 mg g(-1)) for Pb(II), which attributes to the integrated physicochemical adsorption resulting from the oxygen-containing functional groups on the surface of nanohybrid composites. The as-prepared NC-MoS2 exhibits good chemical stability and can be reused 7 times with a slight fading over 80% during cycling, which is essential for its practical applications. All of these demonstrate that NC-MoS2 can be an efficient material for selectively removal of Pb(II), which suggest its great potential in the utilization of environmental cleanup.
