Catalyst preparations used in this study

Preparation	Initial loadinga	Final loading (wt%)	Total metal (wt%)a
A	1% Pd	6.6% Pd/8.4% Pt	15%
B	2% Pd	7.6% Pd/8.4% Pt	16%
C	5% Pd	11% Pd/9% Pt	20%
D	1% Pt	5.6% Pd/9.4% Pt	15%
E	2% Pt	5.6% Pd/10.4% Pt	16%
F	5% Pt	6.0% Pd/14% Pt	20%

^aProportions are in wt% not atomic ratios; atom amount of Pd is approx. twice as much as that of Pt (respective atomic weights are 106.4 and 195.09).
