| Abstract: | A molecularly imprinted polymer-supported gold nanoparticle (Au/MIP) catalyst, which has the characteristics of specific substrate recognition, was prepared by the template complex of 4-nitrobenzyl alcohol (4-NBA) and hydrogen tetrachloroaurate(III), where Au nanaoparticles were formed by the reduction with NaBH4 solution and captured by amino groups (-NH2) in the cavities of the MIP. The obtained samples were characterized with FT-IR spectroscopy, UV-Vis spectroscopy, and scanning electron microscopy. The ... |
