The role of Sn in Pt–Sn/CeO2 catalysts for the complete oxidation of ethanol

Pt and Sn Doped Sputtered CeO2 Electrodes for Fuel Cell Applications

“…It exhibits a Pt 4f 5/2 -4f 7/2 doublet at 72.9 eV corresponding to Pt 2+ [6] and a doublet shifted by 1.4 eV to higher binding energy (BE) corresponding to Pt 4+ [3]. A small peak at 71.8 eV is assigned to the Pt 0 state.…”

“…Pt-cerium oxide systems have been reported to be significantly active catalysts for CO oxidation [1], hydrogen production [2], oxidation of ethanol [3] and decomposition of methanol [4]. High activity for the water gas shift reaction was predicated on the presence of cationic platinum [5,6] in cerium oxide.…”

“…Pt-oxide materials such as Pt-RuO 2 [7] or Pt-SnO 2 [8] and Pt-CeO 2 [9][10][11][12][13] have been reported as promising anode materials for polymer membrane fuel cells (PMFC). Furthermore, the addition of Sn has an important effect on the electronic structure of Pt and its adsorption and reaction properties [3,[14][15][16][17][18][19][20].…”

Influence of the Addition of a Second Metal on the Catalytic Performance of Pt-Beta Agglomerated Catalyst in the Hydroisomerization of n-Octane

“…This peak appeared in the zone of the Pt reduction in the monometallic catalyst. However, the reduction peak of Pt in this catalyst shifted to higher temperature, indicating that the reduction of platinum was depressed by the addition of tin [16]. The second one appeared at temperatures nearby the Sn species that were hardly reducible and could be due to Sn species that did not interact with Pt [17].…”

Remarkable promotion effect of trace sulfation on OMS-2 nanorod catalysts for the catalytic combustion of ethanol

“…Catalytic oxidation is considered to be the most effective technology for this purpose, because VOCs can be oxidized to CO 2 over certain catalysts at much lower temperatures than in thermal oxidation. There are two main types of conventional catalysts used for ethanol oxidation reactions: noble metals (Avgouropoulos et al, 2006;Mitsui et al, 2008;Tang et al, 2005) and metal oxides (Idriss and Seebauer, 2000;Li et al, 2011;Ye et al, 2006;Trawczyñski et al, 2005;Luo et al, 2000). Taking account of economic factors and catalytic properties, recent studies on catalytic oxidation of ethanol have been more focused on metal oxide-based catalysts.…”
