Abstract :
The research paper describes the synthesis of silver nanoparticles in nonaqueous AOT [bis (2-ethylhexyl) sulfosuccinate sodium salt] reverse micellar solution. Complete description of the reverse micellar system is glycerol-AOT-n-heptane reverse micelle where AOT molecules act as surfactant molecule, glycerol as non aqueous polar core solvent and n-heptane as nonpolar hydrocarbon which acts as the dispersion medium. In this study I have used glycerol as nonaqueous polar solvent which was used to create the AOT surfactant core of the reverse micelle and then incorporated silver ion (Ag+) using silver nitrate (AgNO3) salt as precursor material responsible for metal nanoparticle formation. Freshly prepared hydrogen gas (H2) is used as reducing agent to reduce silver ion (Ag+) to silver zero (Ag0) state. Formation and precipitation of large particle was restricted by the cage like templating structure of reverse micelle. I have selected hydrogen gas as reducing agent because of its mild nature and also wanted to minimize the perturbation of natural reverse micelle environment
