Abstract
On page 452, column 1 (lines 12?23) reads: H2 and CO chemisorption show an uptake of 0.91 molH2 molPd?1 and 0.61 molCO molPd ?1, respectively (Table 1, Supporting Information S6). Considering a 1:1 CO/Pd stoichiometry,32 the dispersion from CO chemisorption (D?CO) equals 61%, in a reasonable agreement with the dispersion from TEM (D?TEM 70%; Supporting Information S9).32 While H2 chemisorption is not effective for a determination of the metal dispersion of Pd nanoparticles due to the formation of a stable bulk hydride with larger particles (2.6 nm),32 a comparison of the H2 uptake and D?CO would correspond to approximately three hydrogen atoms per surface Pd.
