文摘

Gd-C-TNSs with high stability and recycle usability were prepared by two-pot method. Gd2O3 loading results in the structure changes of TNSs and increase of the Ti3+ ions. Modified CDs leads to obvious increase of optical absorption ability and red shift. Appropriate amount of Gd2O3 nanoparticles and CDs improve the separation of charges. Gd-C-TNSs exhibit excellent synergistic photocatalytic activity for Cr(VI) and RhB.
