【摘要】 以二水乙酸锌为锌源、氢氧化钾为碱源，采用水热法制备得到棒状氧化锌（ZnO）微米材料。研究了Zn²⁺/OH^-物质的量比、水热温度和表面活性剂对产物晶相的影响，利用X射线衍射仪、扫描电子显微镜、傅里叶红外光谱仪等对ZnO微米材料进行表征。将棒状ZnO微米材料修饰到玻碳电极（GCE）上，利用电化学工作站，在三电极体系中测试了棒状ZnO/GCE分别在碱性环境和酸性环境中的循环伏安曲线。结果表明：棒状ZnO/GCE在KOH溶液中的循环伏安曲线有明显的氧化还原峰，但电化学稳定性较差；在H₂SO₄溶液中氧化还原峰不明显，但稳定性较好。更多还原

【Abstract】 In this paper, rod-like zinc oxides（ZnO） micro materials are prepared by hydrothermal method of using zinc acetate dihydrate as zinc source and potassium hydroxide as alkali source. The effects of different Zn²⁺/OH^- species ratios, hydrothermal temperatures, and surfactant polyethylene glycol on the crystal phase of the products are studied. The as-prepared products are characterized by X-ray diffractometer（XRD）, scanning electron microscope（SEM）, and Fourier transform infrared spectroscopy（FT-IR） and so on. The results show that rod-like ZnO micro materials are modified on a glassy carbon electrode（GCE）, and the cyclic voltammetry（CV） curves of rod-like ZnO/GCE in an alkaline environment and in an acidic environment are tested by using an electrochemical workstation in a three-electrode system. The CV curves in the KOH solution have obvious redox peaks, but the electrochemical stability is poor. In the H₂SO₄ solution, the redox peaks are not obvious, but the stability is good.更多还原
