摘要：

A facile voltammetric sensor based on MnO2 nanorods/electro-reduced graphene oxide composite modified glassy carbon electrode (MnO2NRs-ERGO/GCE) was proposed for the detection of Rhodamine B (RhB). The MnO2NRs-ERGO/GCE was fabricated by a facile drop-casting approach followed by a potentiostatic reduction technique. A well-shaped oxidation peak of RhB was observed at the MnO2NRs-ERGO/GCE, and the response peak current was 17-fold and 2-fold higher than that of bare GCE and ERGO/GCE respectively, attributing to the synergistic electrocatalytic e...
