Mild and Low-Cost Synthetic Process for Monodispersive Platinum Nanoparitcles on Carbon Aerogel

Abstract:

A mild synthetic process using formic acid as the reduction agent was applied to prepare 40 wt% Pt/carbon aerogel (CA) electrocatalyst. The as-prepared sample was characterized by transmission electron microscopy (TEM) and electrochemical measurements. The results exhibit Pt nanoparticles with narrow particle size distribution are dispersed throughout carbon aerogel structure. Moreover, the Pt/CA catalyst has smaller Pt nanoparticle mean size than Johnson Matthey HiSpec^TM4000 (JM4000). The electrochemical measurement results indicate that the Pt/CA catalyst with Pt loading of 40 wt% possesses similar electrochemical surface area (ESA) value and oxygen reduction reaction (ORR) activity as JM4000.
