DNA-templated silver and silver-based bimetallic clusters with remarkable and sequence-related catalytic activity toward 4-nitrophenol reduction†
Abstract
Herein, we report the excellent catalytic activity of DNA-AgNCs toward 4-nitrophenol reduction and a strategy for improving their catalytic performance by forming bimetallic clusters (Ag–Pd, Ag–Au and Ag–Pt). The analogous influence of sequences on the catalytic activity of these nanoclusters is disclosed, which is quite different from their erratic fluorescence properties.
