英文摘要: Precise detection and effectively eliminating mercury pollution in aqueous solutions remains an onerous task for protecting the public health and environment. In this paper, porous MoS2 composite aerogel-supported Au nanoparticles with strong mercury affinity have been fabricated to deal with this problem. Such composite aerogels are fabricated using graphene oxide (GO) doped MoS2 sheets as the feedstock by hydrothermal assembly and then the Au and Fe3O4 nanoparticles (NPs) embed between the GO-doped MoS2 sheets through coordination. The resultant porous Au/Fe3O4/MoS2CAs aerogel not only can sensitively detect mercury(II) in aqueous solution by a colorimetric method with a low detection limit (3.279 nM) but also can exhibit a super mercury adsorption capacity (similar to 1527 mg g(-1)) and fast desorption ability. After magnetic separation, the Hg2+ levels decreased from 10 ppm to 0.11 ppb within a few minutes, which is far below 2 ppb. In addition, Au/Fe3O4/MoS2CAs could be successively recycled more than 10 times with high removal efficiency (>95%). The excellent performance of the composition aerogel profits from its 3D interconnected macroporous framework as well as strong coupling between Au nanoparticles and MoS2 nanosheets, rendering it a potential detection and adsorbent material for mercury(II) from contaminated water for environmental remediation.
