The current study demonstrates the deposition of gold nanoparticles on nonwoven fibers in baby wipes (a mixture of synthetic fiber and cellulose fiber). Au3+ ions are first impregnated into the micronanopores of the nonwoven fibers and then reduced into gold nanoparticles using ascorbic acid as reducing agent. The structure and properties of the composite wipes with deposited nanoparticles were verified by electron microscopy, XPS, FTIR, surface enhanced Raman spectroscopy (SERS) and catalytic reduction tests. The nanoparticles immobilized composite baby wipes exhibited a good catalytic activity for the reduction of 4-nitrophenol to 4-aminophenol in presence of sodium borohydride and demonstrated significant SERS activity for Raman active analyte molecules.
