Abstract
A multi-walled carbon nanotube (CNT)-supported Pt–Ru nanocatalyst prepared by reverse microemulsion was studied for direct methanol electro-oxidation and compared with that made by polyol method. XRD and TEM characterization showed that the reverse micelles-synthesized alloyed particles attained a smaller average particle size and displayed a higher dispersion on the support with narrow size distribution. Results of cyclic voltammetry and chronoamperometry in 1 M methanol + 0.5 M sulfuric acid at room temperature revealed that the Pt–Ru/CNT catalyst synthesized by reverse microemulsion exhibited a much higher electro-catalytic activity than that based on polyol process.
