本文采用简单的水热法将平均直径为50 nm的ZnO纳米棒均匀地固定在碳布表面。沿（002）特定方向沿着原位生长的纳米棒具有单晶特征和柱状结构。基于ZnO纳米棒/碳布复合材料，制备了同时测定苯二酚异构体的自支撑电极。ZnO纳米棒/碳布电极具有良好的电化学稳定性、高灵敏度和高选择性。对苯二酚、邻苯二酚和间苯二酚的线性范围分别为2-30、2-45和2-385 μ M，相应的检测限（S/N = 3）分别为0.57、0.81和7.2 μ M。ZnO/碳布电极具有优异的传感性能，在独立式生物传感器和其他电化学器件的开发中具有很大的应用前景。
Herein, ZnO nanorods with an average diameter of 50 nm were uniformly anchored on the surface of carbon cloth directly by a simple hydrothermal method. The nanorods growing in situ along the specific direction of (002) have single crystalline features and a columnar structure. On the basis of the ZnO nanorod/carbon cloth composite, free-standing electrodes were fabricated for the simultaneous determination of dihydroxybenzene isomers. The ZnO nanorod/carbon cloth electrodes exhibited excellent electrochemical stability, high sensitivity, and high selectivity. The linear ranges of concentration for hydroquinone, catechol, and resorcinol were 2-30, 2-45, and 2-385 mu M, respectively, and the corresponding limits of detection (S/N = 3) were 0.57, 0.81, and 7.2 mu M. The outstanding sensing properties of ZnO/carbon cloth electrodes have a great promise for the development of free-standing biosensors and other electrochemical devices.
