报道了一种基于N掺杂碳包覆TiC纳米纤维阵列（TiC@CNx nfa）的Cr（VI）灵敏电化学传感器。含有CNx外壳的丰富电催化活性位点、高导电性的TiC芯以及TiC@CNx与基体钛合金之间良好的电接触，使该电极具有优异的电化学传感性能。该电化学传感器对Cr（VI）的检测灵敏度为0.88 μA μM−1cm−2，检出限为4.0 nM (S/N=3)，线性范围为0.2 ~ 24.1 μM，具有良好的选择性和抗干扰性。
A sensitive electrochemical sensor for Cr(VI) detection based on N‐doped carbon coated TiC nanofiber arrays (TiC@CNx NFAs) is reported. The abundant electrocatalytic active sites contained CNx shell, highly conducting TiC core, and good electrical contact between the TiC@CNx and underlying Ti alloy endow this electrode with the excellent electrochemical sensing properties. The developed electrochemical sensor shows remarkable determination activity towards Cr(VI) with a high sensitivity of 0.88 μA μM−1cm−2, a low detection limit of 4.0 nM (S/N=3), a wide linear range from 0.2 to 24.1 μM, good selectivity and anti‐interference property.
