摘　　要：Nd2Cu2O4+δnanosheets were synthesized via coordination complex method(CCM)by using[NdCu(3,4-pdc)2(OAc)(H2O)5]·6.5H2O(1,3,4-pdc=3,4-pyridinedicarboxylic acid)as the precursor.Compared to the particles prepared by SSM(simple solution method),Nd2Cu2O4+δprepared by CCM showed leaf-like morphology composed of nanosheets with an average thickness of 50~80 nm and a BET surface area up to 17.9 m^2/g.The Nd2Cu2O4+δsamples exhibit selective adsorption towards malachite green(MG)with significant Qm(maximum adsorption capacity)values reaching up 1.55 g/g at room temperature,and the thermodynamic parameters of adsorption process were obtained.In addition,the properties of selective adsorption of the prepared samples were investigated by temperature change tests.
