Abstract:
Carboxylated pillar[5]arene functionalized silver nanoparticles(CP5A-AgNPs)were successfully prepared by Creighton method.The prepared CP5A-AgNPs composites were characterized by ultraviolet-visible absorption spectroscopy(UV-Vis),infrared spectroscopy(FT-IR)and transmission electron microscopy(TEM),etc.TEM results showed that when the molar ratio of CP5A to AgNO3 was 1:10,the prepared CP5A-AgNPs had good dispersion and uniform particle size,with an average particle size of 4.05 nm.The catalytic degradation ability of CP5A-AgNPs toward two kinds of organic dyes,Rhodamine B(RhB)and methyl orange(MO)was further investigated.The results showed that the degradation rates of these two dyes by CP5A-AgNPs were 99.91%and 98.83%respectively,and CP5A-AgNPs exhibited good cyclic catalytic ability.The catalytic efficiencies in the fifth cycle were 91.06%and 98.45%,respectively.In addition,the performance of functionalized silver nanoparticles using monomer compound of CP5(CMA)as stabilizer(CMA-AgNPs)was compared.The results showed that CP5A-AgNPs had strong catalytic degradation activity to RhB and MO,and had good recycling catalytic ability.
