A Simple CNT Supported Electrocatalysts Preparation Method by Electro-Reduction

Abstract

We developed a novel preparation method of carbon nanotube supported catalysts based on the electrochemical reduction process. Our method doesn't require any organic solvents and additives such as ethylene glycol and surfactants because this is water based process. First, Pt hydroxide nanoparticles are deposited on the hydrochloric acid treated carbon nanotube to prepare so-called pre. Pt/CNT sample. The catalysts with various wt% are prepared through the reduction by applying the potential to our pre. Pt/CNT samples. The obtained catalysts show higher electrochemical active surface area than the commercial Pt/C catalysts.
