SYNTHESIS AND CHARACTERIZATION OF POLY DEOXY CHOLIC ACID ENCAPSULATED COPPER NANOPARTICLES AND ITS CATALYTIC APPLICATION

摘要

The poly (deoxycholic acid) encapsulated copper nanoparticle has been synthesized through condensation polymerization at ambient temperature by using NaBH_4 as reducing agent and ascorbic acid as surface productive agent at basic pH. The rate of the nanoparticle formation will be optimized by varying the concentration of polymer and metal salt. The dye formation depends on the pH, nature of 4 -AAP and the medium. Characterization of newly synthesized copper nanoparticles was analyzed by using UV- vis spectroscopy. FT-IR spectra of the dye formed between aniline and 4-AAP in the presence of copper catalyst was recorded in KBr. The mechanism has been proposed with the help of its kinetics effects. The size of the nanoparticles has been confirmed by TEM analysis.
