Synthesis of PtRu nanoparticles from the hydrosilylation reaction and application as catalyst for direct methanol fuel cell
Article Abstract:
Nanosized Pt, PtRu, and Ru particles are prepared by the process of hydrosilylation reaction and the electrooxidation of liquid methanol on these catalysts is investigated at room temperature by cyclic voltammetry and chronoamperometry. It is concluded that some alloy catalysts have higher catalytic activities and better CO tolerance than the Pt-only catalyst, while Pt(sub 56)Ru(sub 44)/C displays the best electrocatalytic performance among all carbon-supported catalysts.

Microwave synthesis of polymer-embedded Pt-Ru catalyst for direct methanol fuel cell
Article Abstract:
A scalable fabrication process of polymer-imbedded Pt-Ru nanocrystals for direct methanol fuel cell (DMFC) application is described which is easily adapted to any conductive polymer soluble in polar organic solvents. Design and synthesis of novel conductive polymers is needed to enhance the catalytic properties of these hybrid materials.
