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 ...
Two-step sequence for synthesis of efficient PtSn@Rh/C catalyst for oxidizing ethanol and intermediate products
(2012)
PtSn@Rh/C-HT catalysts were designed and synthesized by a two-step sequence synthesis: Rh was firstly deposited on the carbon support and then PtSn through microwave assisted polyol method, followed by the heat treatment ...
Efficient and poison-tolerant PdxAuy/C binary electrocatalysts for glucose electrooxidation in alkaline medium
(2014)
Carbon supported PdxAuy binary catalysts for glucose electrooxidation and detection were prepared by a modified pulse microwave assisted polyol method. The physico-chemical properties were obtained by X-ray diffraction ...
Glucose electrooxidation in alkaline medium: Performance enhancement of PdAu/C synthesized by NH3 modified pulse microwave assisted polyol method
(2015)
Lack of highly efficient and stable electrocatalysts for glucose electrooxidation is a bottleneck for the real application of glucose fuel cells and electrochemical sensors. Herein we report the synthesis of the PdAu/C ...
Direct ethanol fuel cells: The effect of the cell discharge current on the products distribution
(2010)
In the present work the results of the continuous and on-line product analysis during a Direct Ethanol Polymer Electrolyte Membrane Fuel Cell operation (DE-PEMFC) are presented. The effect of both cell discharge current ...
Study of the products distribution during a direct ethanol PEM fuel cell operation
(2011)
In the present work the effect of both cell discharge current and operating temperature on (a) the ethanol conversion, (b) the reaction products distribution and (c) the reaction yield towards each released product, during ...
The effect of microwave operation parameters on the electrochemical performance of Pt/C catalysts
(2011)

A facile soft-template synthesis of ordered mesoporous carbon/tungsten carbide composites with high surface area for methanol electrooxidation
(2012)
Ordered 2D hexagonal mesoporous carbon/tungsten carbide (OMC/WC) composite nanomaterials have been successfully synthesized for the first time by the soft-template method with ammonium metagungstate as tungsten precursor ...
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 ...
