Technical electrodes catalyzed with PtRu on mesoporous ordered carbons for liquid direct methanol fuel cells

Impact of the Various Catalysts (Pt, Pt-Ru) Deposited onto Carbon Support to the Slow Oxygen Reduction Reaction Kinetics

“…The size of C(Mo 2 C) crystallite (L a = 1.8 nm) is slightly higher compared with C(WC) (L a = 1.6 nm). The apparent crystallite sizes along c-and a-directions of the graphite structure could be calculated from the XRD data using Debay-Scherrer equations (9,10). The results of the XRD calculations agree with the analysis of Raman spectra for these carbons (12,13).…”

Carbon-Supported Pt-Based Alloy Electrocatalysts for the Oxygen Reduction Reaction in Polymer Electrolyte Membrane Fuel Cells: Particle Size, Shape, and Composition Manipulation and Their Impact to Activity

“…Interestingly, using Pd as the second metal in PtM/C catalyst was found not only to enhance the ORR activity but also to increase the catalyst's methanol tolerance. 259,260 Among various carbon-supported PtM nanoparticle alloy catalysts, core−shell structured alloy catalysts with M or PtM alloy as the core and Pt as the shell have been found to exhibit considerably higher performance for the ORR than pure Pt/C. Strasser's group 261,262 has synthesized a series of core−shell structured PtM/C (M = Co, Cu) catalysts with PtM alloy as the core and Pt as the shell through a dealloying process.…”

Oxygen Reduction Reaction in Alkaline Solution: Influence of Catalyst Loading and Carbon Support Characteristics

“…The Pt-nanoparticles were deposited onto the carbon support by the sodium borohydride reduction method (14,15). Commercially available modified carbon 20wt% Pt-VulcanXC72 ® (Fuel Cell Earth, LLC, Wakefield, Massachusetts, USA) was used as a reference material, named as Pt-V.…”
