Synthesis and Characterization of Shape Controlled Platinum Metal Catalyst

Abstract

The catalytic and electro catalytic properties was determined by using size and shape of platinum nanoparticles . To produce well defined and controllable shapes of platinum nanoparticles and improve their performance in terms catalytic activity and selectivity many chemical methods has been developed. Synthesis of colloidal platinum nanoparticles in three different shapes by using polyol synthesis method, Polyvinylpyrrolidone (PVP) as a reducing agent in first method. Ethylene glycol has been used as a solvent and addition of silver ions for enhances the crystal growth. Sodium borohydride has been used as the reducing agent in the second method. Most of the papers silver nanoparticles were synthesized. In this paper we try the potassium chloroplatinate has to be reducing platinum nanoparticles by sodium borohydride. The same methods to be using a silver nitrate is convert to silver nanoparticles by using the same reducing agents
