The role of sodium surface species on oxygen charge transfer in the Pt/YSZ system
(Elsevier Limited, 2012-08-01)
The role of sodium surface species in the modification of a platinum (Pt) catalyst film supported on 8 mol% yttria-stabilised-zirconia (YSZ) was investigated under a flow of 20 kPa oxygen at 400°C. Cyclic and linear sweep ...
The role of low coverage sodium surface species on electrochemical promotion in a Pt/YSZ system
(Elsevier B.V., 2012-10-04)
The effect of sodium-modification on the catalyst and electrocatalytic properties of a platinum catalyst supported on a YSZ solid electrolyte was studied. Increasing the sodium coverage on the catalyst surface appears to ...
Influence of impurities and catalyst surface characteristics on the oxygen charge transfer reaction in the Pt/YSZ system
(Elsevier B.V., 2012-10-04)
Spillover processes (i.e. the migration of ionic species from the support to the catalyst and vice versa) are known to play a very important role in catalysis and electrocatalysis. These spillover processes can be influenced ...
