Abstract
- In this work, we synthesized bimetallic Cu nanowires@Pd (Cu NWs@Pd) by a facile replacement reaction. Benefiting from the structure anisotropy, the sensor constructed by Cu NWs@Pd with diameter of 40 nm exhibited a superior sensitivity (1363.7 ± 23.5 µA·mM<superscript>−1</superscript>·cm<superscript>−2</superscript>), which is ca. 11.06-folds higher than that for analogous Cu nanoparticles@Pd. Moreover, the synergistic effect of bimetallic metal enables the Cu NWs@Pd an enhanced sensor performance. At applied potential of 0.8 V vs Ag/AgCl, the sensitivity of Cu NWs@Pd is much higher than that of analogous Cu NWs. And the enhanced factor could reach 2.41. As 0.2 V vs Ag/AgCl was applied, detection range for the Cu NWs@Pd could up to 26.0 mM, which is ca. 1.37-folds for the pure Pd NPs. The preferable performance can be extended to the detection of H<subscript>2</subscript>O<subscript>2</subscript>. This work showed the non-enzymatic sensor with wide detection range and preferable sensitivity by Cu NWs@Pd, which would provide an efficient strategy to cope with the challenges for the commercialization of non-enzymatic sensor.
