摘要：

An in situ strategy has been developed to directly grow Au nanoparticles (NPs) on the surfaces of Cu2O nanocubes by exposing Cu2O nanocubes to diluted HAuCl4 solution at room temperature. The sensing performances of the Cu2O nanocubes toward ethanol and acetone improved significantly after the growth of the Au NPs.
