Ternary Pt–Ru–SnO2 hybrid architectures: unique carbon-mediated 1-D configuration and their electrocatalytic activity to methanol oxidation

Functionalizing Reduced Graphene Oxide with Ru‐Organometallic Compounds as an Effective Strategy to Produce High‐Performance Pt Nanocatalysts for the Methanol Oxidation Reaction

“…Furthermore, as has been indicated elsewhere, CO ads species poison the Pt catalytic sites, decreasing the catalytic activity of Pt/C electrocatalyst. The use of rGO has been considered as an attractive option to Vulcan, aiming to increase the tolerance of Pt to CO ads due to metal‐support interactions, which causes a shift in onset potential of the CO oxidation reaction towards more negative potentials . Then, the Pt‐active sites become free to continue with the reaction.…”

Anode Catalysts for Direct Methanol Fuel Cells in Acidic Media: Do We Have Any Alternative for Pt or Pt–Ru?

“…Yang et al synthesized SnO 2 @C core−shell nanochain 3D superstructures to be used as a support for Pt−Ru nanoparticles. 57 Since dissolution of SnO 2 creates tin ions, which catalyze redox coupling of Pt species, it is necessary to prevent or control the dissolution of SnO 2 in acidic media. A core−shell structure of SnO 2 @C and a sandwich structure of Pt−Ru− SnO 2 −C are beneficial for methanol oxidation in acidic media.…”

Electroless synthesis of two-dimensional sandwich-like Pt/Mn3O4/reduced-graphene-oxide nanocomposites with enhanced electrochemical performance for methanol oxidation

“…In addition, to mitigate the corrosion of the supports and improve the durability of the electrocatalysts, transition metal oxides such as TiO 2 [7,8], SnO 2 [9], CeO 2 [10,11] and MnO 2 [12] have been widely utilized as the support for noble metal nanoparticles, which is due to their remarkable resistance to acid or alkali, their excellent thermal stability under harsh working conditions, and also their ability to improve CO tolerance in methanol oxidation [11,13]. Among various transition metal oxide supports, Mn 3 O 4 is a potentially interesting electrocatalyst support material by its low cost, environmental compatibility, electrochemical and catalytic properties.…”
