CO tolerance of Pt3Sn(111) catalyst in ethanol decomposition.
CO tolerance is one of the crucial factors to protect catalysts against inactivation along ethanol decomposition processes. Herein, the intrinsic essence of CO tolerance and the effect of alloying element Sn in Pt3Sn(111) are investigated by combining periodic density functional theory (DFT) and microkinetic modelling. It is found that the most competitive route to CO proceeds via CH3CH2OH [righ...
