title: Fe3N-Co2N Nanowires Array: A Non-Noble-Metal Bifunctional Catalyst Electrode for High-Performance Glucose Oxidation and H2O2Reduction toward Non-Enzymatic Sensing Applications.
abstract: Among reported electrode materials, a nanoarray is an attractive architecture for molecular detection because of its large specific surface area and easy accessibility for target molecules. Here, a new Fe3N-Co2N nanowires array grown on carbon cloth (Fe3N-Co2N/CC) is reported as a non-noble-metal bifunctional catalyst electrode for high-performance glucose oxidation and H2O2reduction. As an electrochemical non-enzymatic sensor for glucose detection, Fe3N-Co2N/CC shows a fast response time of 8 s, a low detection limit (LOD) of 77 nm (signal/noise=3), and a high sensitivity of 4333.7 μA mm-1cm-2. As an H2O2sensor, it shows a LOD of 59 nm (signal/noise=3) and a sensitivity of 2273.8 μA mm-1cm-2with a response time of 2 s. In addition, the proposed sensor is stable with high selectivity, specificity, and reproducibility, and its application for real sample analysis has been successfully demonstrated.
