Herein, we develop new photocatalysts based on the graft of three different cyclodextrins (α-CD, β-CD and γ-CD) on MoS₂/g-C₃N₄ composites (CDs/MoS₂/g-C₃N₄) for the removal of glyphosate and Cr (VI) from simulated agricultural runoff. CDs/MoS₂/g-C₃N₄ show remarkably enhanced photocatalytic activities for glyphosate degradation and Cr (VI) reduction compared to pristine MoS₂/g-C₃N₄. In addition, γ-CD/MoS₂/g-C₃N₄ exhibits the highest hydrophilicity and photocatalytic activity among these three different cyclodextrins grafted MoS₂/g-C₃N₄. The mechanistic investigation indicates that cyclodextrins can not only increase the accumulation of glyphosate and Cr (VI) onto the surface of CDs/MoS₂/g-C₃N₄ but also facilitate the fleet separation of photo-induced electron-hole pairs. In summary, these results collectively imply that the graft of cyclodextrins could be an effective strategy to improve the photocatalytic efficiency of MoS₂/g-C₃N₄ composites for the removal of glyphosate and Cr (VI) from simulated agricultural runoff.]]> Wed 04 May 2022 15:10:42 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:53200 Fri 17 Nov 2023 12:04:28 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38432 Fri 10 Sep 2021 14:50:32 AEST ]]>
