摘要

我们证明了精确控制合成pH值可以选择性地合成促氧化纳米酶或抗氧化纳米Cu簇（CuNCs）。值得注意的是，调节生长温度可以将其催化活性从促氧化纳米酶转变为抗氧化纳米酶。这种可调性可能使远程控制铜纳米酶的催化活性成为可能。

Extremes meet: changeover between pro- and antioxidant activities of Cu-based nanozymes†

We demonstrate that precise control of the synthetic pH enables the selective synthesis of either pro-oxidant Cu nanoclusters (CuNCs) or antioxidant CuNCs. Notably, modulating the growth temperature of CuNCs can switch their catalytic activity from a pro-oxidant to antioxidant nanozyme. This tunability may make it possible to remotely control the catalytic activities of Cu nanozymes.
