“…This leads to degradation in the performance as well as low durability of fuel cells. 5,6 Considerable efforts have been devoted to the development of alternative electrocatalyst supports. The discovery of the one dimensional allotrope of carbon, carbon nanotubes by Iijima in 1991 7 opened a new era in science and engineering.…”

The development of inexpensive and highly active ethanol electro-oxidation electrocatalysts is a great challenge. Here, we report a novel material consisting of platinum dispersed on a bi-metal oxide grown carbon nanostructure as an ethanol electro-oxidation electrocatalyst. The carbon nanostructure has been synthesized by the catalytic chemical vapour deposition of acetylene precursor over Fe-Sn-O particles. Platinum (Pt) nanoparticles have been decorated on a bi-metal oxide grown carbon nanostructure (CNS-FSO) by the polyol reduction technique. The suitability of the electrocatalyst for ethanol electro-oxidation is examined by cyclic voltammetry and amperometry techniques. Pt supported on CNS-FSO exhibited a higher catalytic activity towards ethanol electro-oxidation in comparison to commercially available platinum on Vulcan XC-72 and platinum nanoparticles decorated functionalized multi walled carbon nanotubes. This superior activity can be attributed to the unique properties of CNS-FSO as well as the synergic effect between platinum and CNS-FSO.

“…In recent years, many electrocatalysts such as Pt-based bimetallic electrocatalysts [4][5][6][7][8][9], tri-metallic electrocatalysts [10][11][12] and multi-metallic electrocatalysts [13] have been investigated by many investigators. However, most of preparation methods are too complicated to satisfy the requirement of mass production.…”

This work presents investigations on preparation of 20 wt. % Pt0.5Pd0.5/C nanoelectrocatalysts by electroless and their electrocatalytic properties. The 20 wt. % Pt0.5Pd0.5/C nanoelectrocatalysts were prepared by electroless successfully. The optimum experimental conditions of the main effect factors in preparing the PtPd nanoelectrocatalysts are [Pt2+ or Pd2+] =2-10g/L, [HCHO] =10-20g/L, temperature: 40-60°C, the dosage of protection reagent: 1-3 % of the platinum and palladium content, the agitation rate 400-500r/min. The characterization of 20 wt. % Pt0.5Pd0.5/C was performed with cyclic voltammetry (CV) and transmission electron microscope (TEM), respectively. Particles of PtPd are distributed symmetrically on C by TEM, of which are very small and the average granularity is less than 3nm. The nanoelectrocatalysts have high stabilization and lots of catalysis nuclei through CV.
