   Amido-amino functionalized halloysite stabilized copper nanoparticles (aah-CuNPs) were synthesized through one-pot protocol by a wet chemical method using hydrazine as reducing agent. The nanocomposite formed was stable in dry ethanol. The composition and binding nature of the nanocomposite were studied using FT-IR, DRS-UV, EDAX and powder XRD techniques. The morphological features of the composite were obtained from HRSEM analysis. The thermal stability of the copper nanocomposites was studied using TGA analysis. The prepared nanocomposite displayed broad spectrum antimicrobial activity, and it was very effective in Ullmann aromatic amination reaction.
