摘要
研究了采用氨化和表面修饰镓、铈、锡氧化物法对石墨毡进行表面处理,借助扫描电镜、红外光谱仪、X-射线衍射仪表征氨化处理后并修饰金属氧化物的石墨毡的表面形貌和电化学性能。结果表明:氨化处理后的石墨毡表面均匀,修饰金属氧化物后电化学活性增强;修饰氧化锡的石墨毡电化学活性最好。
The surface treatment of graphite felt was studied by ammoniation and surface modification using gallium,cerium and tin oxide.The surface morphology and electrochemical properties of the modified graphite felt were characterized by scanning electron microscope,infrared spectrometer and X-ray diffraction instrument.The results show that the surface of the modified graphite felt is uniform,the electrochemical activity is enhanced.Graphite felt modified with tin oxide has the best electrochemical activity.
