Synthesis and characterization of silver/clay/starch bionanocomposites by green method

In this study, we report an effective process for preparing silver nanoparticles (Ag NPs) by using Green reduction method of AgNO3 in interlamellar space of Montmorillonite/Starch Bionanocomposites (MMT/Stc BNCs) suspension with moderate temperature. In here MMT, Starch, β-D-glucose and AgNO3 were u...
