Understanding the electrocatalytic activity of PtxSny in direct ethanol fuel cells
(2011)
In the present work, the activity of PtxSny/C catalysts towards ethanol, acetaldehyde and acetic acid electrooxidation reactions is investigated for each one separately by means of cyclic voltammetry. To this purpose, a ...
High surface area tungsten carbide microspheres as effective Pt catalyst support for oxygen reduction reaction
(2009)
In the present work, the preparation of high surface area (256 m2 g-1) tungsten carbide microspheres (TCMSs) by the aid of a simple hydrothermal method is realized and the performance of the Pt electrocatalyst supported ...
Ordered mesoporous tungsten carbide/carbon composites promoted Pt catalyst with high activity and stability for methanol electrooxidation
(2014)
The current anode materials used for direct methanol fuel cells (DMFCs) are expensive and not sufficiently durable for commercial development. One of the major challenges lies in the development of an inexpensive, efficient ...
