“…Therefore, reduced GNO presents two inherent advantages; firstly the electrical conductivity of reduced GNO is almost similar to that of GN and secondly, its residual oxygen functionalities sometimes help to adsorp the analyte. Especially, the oxygen functionalities of GNO have been utilized for the adsorption of uranium [9][10][11][12][13][14][15].…”

Composites of layered double hydroxides( LDHs) and graphene (G) are excitingn anomaterials because of their uniques urface structures and excellent physicochemical properties. Such materials offer the advantages of both components,t hat is, the large surfacea rea and ample functional groups of graphene and the outstanding layered structure and ion-exchangeability of layered double hydroxides, whilst effectively avoiding the coagulation of graphene and the instability of pristine layered double hydroxides,a nd they have been widelyi nvestigated for applications in water remediation. This Minireview begins by summarizing the most common methods for the synthesis of G@LDH composites, including hydrothermalt reatment, coprecipitation, and in situ growth. Then, we review the adsorption and catalytic ability of G@LDH materials in the removal of contaminants from water,s uch as heavy metal ions, radionuclides, dyes, and other organic pollutants. Finally,w ed iscusst he challenges and offer ap erspective on the directions of future research of G@LDH composites.

Enrichment of U VI is an urgent project forn uclear energy development. Herein, magnetic graphitic carbon nitride nanosheets were successfully prepared by in situ anchoringo fp yrrhotite( Fe 7 S 8 )o nt he graphitic carbon nitride nanosheet (CNNS), whichw ere used for capturing U VI .T he structural characterizations of Fe 7 S 8 /CNNS-1 indicated that the CNNS could prevent the aggregation of Fe 7 S 8 and the saturation magnetization was4 .69 emu g À1 ,w hich meant that it was easy to separatet he adsorbent from the solution. Adsorption experiments were performed to investigate the sorptionp roperties. The results disclosed that the sorption data conformed to the Langmuir isotherm model with the maximum adsorptionc apacity of 572.78 mg g À1 at 298 K. The results of X-ray photoelectron spectroscopy (XPS) demonstrated that the main adsorption mechanism are as follows:U VI is adsorbed on the surface of Fe 7 S 8 /CNNS-1 through surfacec omplexationi nitially,t hen it wasr educed to insoluble U IV .T hereby,t his work provideda ne fficient and easy to handle sorbent material for extractiono fU VI .Supporting information and the ORCID identification number(s) for the author(s) of this article can be found under: https://doi., Fuel Process. Technol. 2001, 71,99.Scheme2.Aschematic diagram of the use of Fe 7 S 8 /CNNSf or the adsorption and reduction of uranium(VI).
