Composition-Dependent Catalytic Activity of Bimetallic Nanocrystals: AgPd-Catalyzed Hydrodechlorination of 4‑Chlorophenol

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_<i>x</i> (<i>x</i> = 2, 4, 6, 9, 19) showed pronounced composition-dependent catalytic activities, leading to the AgPd₉ catalyst with excellent activity
