The investigation of the electrocatalytic effect of nanocomposites polyaniline films modified with platinum.

Abstract

Polyaniline (PAni) is relatively stable in the air even at very high temperatures. His indomitable nature is due to its instability, fragility, high pH dependence of the conductivity and electrochemical activity of the environment, and limitation of application. Therefore, efforts to change the structure of PAni have been made to deal with these problems. Between copolymers and composites, the yen has been considered as an important way to improve its properties. The use of conductive polymers as a support for catalytic platinum particles for the oxidation of hydrogen ions and small organic molecules has been the focus of many researchers, usually platinum is used as an ideal catalyst for these processes. The main reason for studying such composite materials is their extraordinary electrocatalytic activity, which is comparable to platinum electrode or even much more .
