CO tolerance and durability study of PtMe(Me = Ir or Pd) electrocatalysts for H2-PEMFC application
(2021)In the present work, carbon supported PtMe (Me = Ir or Pd) electrocatalysts, with different atomic ratios (Pt/Me (20 wt%) = 3:1, 1:1, 1:3), are thoroughly investigated towards CO tolerance and durability, as anode and ... -
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 ... -
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 ... -
Oxygen reduction and hydrogen oxidation reaction on novel carbon supported PdxIry electrocatalysts
(2018)In the present work Vulcan XC-72 carbon supported Pd, Ir and PdxIry (with x:y atomic ratios of 3:1, 1:1, 1:3) electrocatalysts are thoroughly investigated for the reactions of hydrogen oxidation (HOR) and oxygen reduction ... -
PdxRuy/C binary catalysts for glucose electrooxidation
(2013)PdxRuy/C (x:y=1:2, 1:3, 2:1 and 3:1) electrocatalysts are prepared by a modified pulse microwave assisted polyol method and are studied for glucose electrooxidation in alkaline media. The effects of glucose's concentrations ... -
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 ... -
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 ...
