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 Reaction over PtFeM (M = Mo, V, W) Alloy Electrocatalysts: Role of the Compressive Strain Effect on Pt
(2019)The high level loading requirement of platinum and the sluggish oxygen reduction kinetics - catalyzed by platinum-based electrocatalysts - create major bottlenecks for cost-effective application of fuel cell technology. ... -
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 ... -
Single-atom catalysis for zinc-air/O2 batteries, water electrolyzers and fuel cells applications
(2022)We summarize the latest progress achieved in precious and non-precious carbon based single-atom catalytic active sites, including Pd, Pt, Ir, Ru, Rh, Au, Fe, Co, Mn, Zn, Sn, and Cu, aiming at facilitating metal-air/O2 ... -
Ternary Mo2NiB2 as a Superior Bifunctional Electrocatalyst for Overall Water Splitting
(2022)Transition metal borides are considered as promising electrocatalysts for water splitting due to their metallic conductivity and good durability. However, the currently reported monometallic and noncrystalline multimetallic ... -
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 ... -
Very low Pt-Pd based electrocatalysts for oxygen reduction reaction
(2015)In the present manuscript very low-platinum electrocatalysts, Pd97Pt3/C, Pd98Pt2/C, Pd99Pt1/C and pure Pd/C are prepared and examined for oxygen reduction reactions (ORR) with the rotating electrode technique. From the ...
