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.

Key words: β-cyclodextrin, catalysis, gold nanoparticles, molecular selectivity, organic-inorganic hybrid materials
