采用硬模板法制备了一种具有高比表面积（1600 m2/g）、大孔容（1.6 cm 3/g）和开孔结构的新型有序介孔炭（OMC）。这种多孔碳材料为电化学应用提供了放大的靶-受体界面。采用微分脉冲伏安法研究了新型电极材料OMC对酪氨酸（Tyr）和半胱氨酸（CysH）同时电氧化的催化活性。值得注意的是，在生理pH下，在OMC电极上首先观察到Tyr和CysH的良好分离的氧化峰。在CysH存在下进行Tyr的选择性测定。更重要的是，该传感器能很好地将Tyr与抗坏血酸、多巴胺、尿酸、肾上腺素等区分开来，表明该传感器在生理系统中具有良好的抗干扰能力。
In this study, a novel ordered mesoporous carbon (OMC) with high surface area (1600 m2/g), large pore volume (1.6 cm3/g) and open pore structure was successfully prepared by using a hard-templated method. This porous carbon material provided an amplified target-receptor interface for the electrochemical application. As a novel electrode material, the catalytic activities of OMC towards simultaneous electro-oxidation of tyrosine (Tyr) andl-cysteine (CysH) were investigated by differential pulse voltammetry. Significantly, well separated oxidation peaks of Tyr and CysH were firstly observed at physiological pH at the OMC electrode. Selective determination of Tyr was carried out in the presence of CysH. More importantly, well distinguishing Tyr from ascorbic acid, dopamine, uric acid, epinephrine was also demonstrated, suggesting an excellent anti-interference ability of this Tyr sensor in the physiological system.
