摘要/Abstract

摘要： 提出了一种新的氧化物电极制备方法: 微波热解法. 分别采用微波热解法及刷涂热解法来制备电极. 通过SEM、XRD、强化寿命、线性扫描等测试手段对两种电极进行了比较. 以酸性红G为目标物考察两种电极的电催化性能. 与传统刷涂热解法相比, 微波热解法所需操作时间较少(2 h), 操作步骤及强度也较低. 结果表明, 新方法制备得到的电极在表面形貌、氧化物晶型、电极稳定性、氧析出电位及电催化性能等方面, 相比于传统方法制备的电极, 均有一定程度的提升.

关键词: 微波法, 刷涂法, SnO₂电极, 电极性能

Abstract: A novel method of microwave irradiation assisted thermal decomposition to prepare metal oxide electrodes was proposed in this paper. The electrodes were prepared by the microwave irradiation and the dip-coating method, respectively. The as-prepared electrodes were characterized with scanning electron microscope (SEM), X-Ray Diffraction (XRD), linear sweep voltammetry and accelerated life test to find out the difference between the novel method and the traditional one. Wastewater degradation experiment was also carried out using the electrodes prepared with the above mentioned approaches, with Acid Red G as target pollutant. In comparison with the traditional dip-coating thermal decomposition method, the microwave irradiation method takes less time (2 h) and less complicated operation procedure. The results demonstrate that the electrode prepared by the novel microwave method is better in surface morphology, crystalline, stability and electro-catalytic property, comparing with that prepared by traditional method.

Key words: microwave irradiation, dip-coating method, tin dioxide electrode, electrode property
