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.

摘要

在此，我们报道了 DNA-AgNCs 对 4-硝基苯酚还原的优异催化活性，并提出了一种通过形成双金属簇（Ag-Pd、Ag-Au 和 Ag-Pt）来提高其催化性能的策略。揭示了序列对这些纳米簇催化活性的类似影响，这与它们不稳定的荧光性质有很大的不同。
