Abstrakt: A graphene microfiber (GF) modified with ultrafine Cu x O nanoparticles (Cu x ONPs/GF) has been fabricated by direct annealing of electrodeposited nano-sized copper-based metal organic frameworks (HKUST-1) and used as an electrode for nonenzymatic H 2 O 2 sensing. Benefiting from the unique microfiber architecture and synergetic effects, as well as strong coupling between components with many active sites and boosted electron transport, the Cu x ONPs/GF electrode shows prominent sensitivity, selectivity and long-term operational stability for the detection of H 2 O 2 . Further work successfully applied this Cu x ONPs/GF electrode to detection of H 2 O 2 in real samples such as milk and human serum. These results indicate that the Cu x ONPs/GF is a promising mini-sized sensor in electrochemical analysis.
