چکیده
Platinum deposited on dispersed materials has so far been the most demanded catalyst for creating cathodes a wide range of electrochemical power sources. This paper sets out to investigate effect carbon nanotube (CNT) modification by O, N, and P atoms structural, electrocatalytic, corrosion properties as-synthesized monoplatinum catalysts. The investigated Pt/CNTmod catalysts showed an increased electrochemically active platinum surface area electrical conductivity, as well catalytic activity in oxygen reduction reaction (ORR) alkaline electrolytes. improved characteristics Pt/CNT are explained alterations composition number groups, which formed CNT surface, their electronic structure. By sum main characteristics, Pt/CNTHNO3+N Pt/CNTHNO3+NP promising use cathode media.

Electrocatalytic oxidation of hydrogen peroxide and cysteine at a glassy carbon electrode modified with platinum nanoparticle-deposited carbon nanotubes.
A glassy carbon electrode modified with platinum nanoparticle-decorated carbon nanotubes (Pt-CNT/GCE) was prepared. The electrochemical behaviors for the catalysis oxidations of hydrogen peroxide and cysteine were studied. The Pt-CNT/GCE showed catalytic activity for electro-oxidation of hydrogen peroxide at 0.6 V in PBS (pH = 7.0) and for that of cysteine at 0.55 V in sulfuric acid medium (pH ...
