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 ...
The effect of microwave operation parameters on the electrochemical performance of Pt/C catalysts
(2011)
In the present work, the effect of the microwave operation parameters on the heating behaviour of ethylene glycol (EG) solution and thereafter on the physicochemical and electrochemical properties of Pt/C catalysts have ...
Direct alcohol fuel cells: A novel non-platinum and alcohol inert ORR electrocatalyst
(2008)
In the present investigation, a series of binary PdxFey/C electrocatalysts for the oxygen reduction reaction (ORR) was synthesized in a very short time by employing a pulse-microwave assisted polyol method. The physico-chemical ...
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 ...
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 ...
Preparation of graphitic mesoporous carbon for the simultaneous detection of hydroquinone and catechol
(2013)
A graphitic mesoporous carbon (GMC) had been successfully synthesized using Ni-Fe layered double hydroxide (LDH) as both template and catalyst under a relatively low pyrolysis temperature. The techniques of X-ray diffraction, ...
Ceria promoted Pd/C catalysts for glucose electrooxidation in alkaline media
(2015)
Carbon support materials are modified by CeO2 through a microwave decomposition method, and then CeO2-C supported Pd catalysts are synthesized by a pulse microwave assisted polyol method. The content of CeO2 is appropriately ...
An investigation of WC stability during the preparation of Pt@WC/OMC via a pulse microwave assisted polyol method
(2015)
In the present work, the WC stability during the preparation of Pt@WC/OMC (Ordered Mesoporous Carbon) electrocatalysts, through a pulse microwave-assisted polyol method, is investigated by the aid of X-ray diffraction and ...
