摘要：
The Cu@Pt/C nanocomposites have been synthesized via two-step reduction method. Electrochemical observations showed that the Cu@Pt/C had better electrocatalytic activity for the reduction of hydrogen peroxide than Pt/C, with a wide linear range between 0.50 mu M and 32.56 mM, a high sensitivity of 351.3 mu A mM(-1) cm(-2), and a low detection limit of 0.15 mu M (signal/noise = 3). Furthermore, the sensor based on Cu@Pt/C has potential applications due to its excellent long-time stability, good reproducibility and acceptable selectivity. (C) 2017 Elsevier B.V.
