Abstract
Ag–Pd bimetallic nanocrystals
(NCs) with tunable compositions and narrow size distributions were
produced by a one-pot synthesis. The NC growth process was investigated
by time-dependent TEM, XRD, and UV–vis studies. In the hydrodechlorination
of 4-chlorophenol, the AgPd<sub><i>x</i></sub> (<i>x</i> = 2, 4, 6, 9, 19) showed pronounced composition-dependent
catalytic activities, leading to the AgPd<sub>9</sub> catalyst with
excellent activity
