NanoEmulsion for Nanotechnology Size-Controlled Synthesis of Pd (II)Nanoparticles via NanoEmulsion Liquid Membrane

Abstract

Palladium nanoparticles with low polydispersity were fabricated via emulsion globules of various sizes with same sauter mean diam. has been proposed for this purpose. In this paper, the important variables affecting sauter mean diam. of the emulsion drops, including injection method of emulsion, stirring speed, oil phase viscosity, compn. of inner water phase and solute permeation rate are also systematically investigated of HCl/Co (III) dicarbolide/xylene/HCl forming (PdCl4)-2 in the presence of span 80/85 as the surfactants. The particle size, ranging from 3.2 to 4.2 nm, was optimized be controlled by variation of the surfactant, the agitation time and the concns. Nano emulsions were prepd. using the spontaneous emulsification mechanism as non-equil. systems. XRS, SEM and surface area were used for anal. and the optimized coditions of nanopalladium was 2.5, 1.1 and 0.1 for O/S, glouble diam. and polydispersity resp. The studies on optimization methods for nano-emulsion gloubles be a required. [on SciFinder(R)]
