Abstract
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.
期刊介绍：
Reviews in Analytical Chemistry publishes authoritative reviews by leading experts in the dynamic field of chemical analysis. The subjects can encompass all branches of modern analytical chemistry such as spectroscopy, chromatography, mass spectrometry, electrochemistry and trace analysis and their applications to areas such as environmental control, pharmaceutical industry, automation and other relevant areas. Review articles bring the expert up to date in a concise manner and provide researchers an overview of new techniques and methods.
