Abstract
ABSTRACTThe aim of this study was to investigate the application of modified clay as a support in the synthesis of silver nanoparticles. Silver nitrate (AgNO3) was used as the silver precursor in several concentrations (0.005 M, 0.01 M, 0.02 M, 0.05 M, and 0.1 M) to obtain Ag-MMT purified and modified clay nanocomposites. The properties of nanocomposites were also studied as a function of the concentration of the reducing agent, sodium borohydride (NaBH4). It was observed through X-ray Diffraction that the MMT purified structure was gradually exfoliated with increased concentrations of AgNO3, while the modified clay structure remained intact. As observed through UV-vis spectra, samples of Ag+-MMT were reduced with NaBH4 to produce Ago and its particle diameter is dependent on the concentration of NaBH4.
