利用NaBH4L-半胱氨酸(L-Cys),采用一种简单的还原方法合成了L-Cys-β-CD@AuNPs纳米粒子.研究了L-Cys-β-CD@AuNPs对4-硝基苯酚和4-硝基-1-萘酚的还原催化活性,结果表明:L-Cys-β-CD@AuNPs纳米粒子对4-硝基苯酚和4-硝基-1-萘酚的还原活性不同,由于β-环糊精(β-CD)与不同客体分子的选择性结合,对不同底物具有不同的催化活性.实验结果表明,L-Cys-β-CD@AuNPs对4-硝基-1-萘酚的还原反应效率优于对硝基苯酚.

L-Cys-β-CD@AuNPs nanoparticles were synthesized by a simple method of the reduction of HAuCl4 with NaBH4and L-Cys-CD. The catalytic activity of L-Cys-β-CD@AuNPs nanoparticles for the catalytic reductions of 4-nitrophenol and 4-nitro-1-naphthol was researched in detail. Because of the selective binding of β-cyclodextrin (β-CD) to different guest molecules, L-Cys-β-CD@AuNPs exhibits diverse catalytic activities for different substrates. The experimental results prove that L-Cys-β-CD@AuNPs shows better catalytic efficiency for the reduction of 4-nitro-1-naphthol than p-nitrophenol.
