摘要

摘要基于氧化亚铜负载的银修饰还原氧化石墨烯纳米复合材料，构建了一种非酶促H2O2传感器。结果表明，该传感器对H2O2具有良好的检测性能，检测限为0.34 μM，检测范围为1 ~ 310 μM。石墨烯与银和氧化亚铜的结合提高了传感器检测H2O2的灵敏度，具有良好的重复性、选择性和稳定性。该纳米复合材料的合成方法为石墨烯基纳米复合材料的绿色制备提供了新思路，也为构建新型电化学传感器平台提供了新方法。

Preparation of cuprous oxide-supported silver-modified reduced graphene oxide nanocomposites for non-enzymatic electrochemical sensor

Abstract We constructed a non-enzymatic H2O2 sensor based on cuprous oxide-supported silver-modified reduced graphene oxide nanocomposites. It was found that the sensor exhibited good performances for sensing H2O2 with a detection limit of 0.34 μM and a wide detection range of 1–310 μM. The combination of graphene with silver and cuprous oxide improved the sensor’s sensitivity for detecting H2O2, with good repeatability, selectivity, and stability. The synthesis method of this nanocomposite provides a new idea for the green preparation of graphene-based nanocomposites and a new method for the construction of a new electrochemical sensor platform.
