摘要
通过电沉积和化学还原过程在碳纸表面负载Co(OH)_(2)-Co纳米片,制得氢氧化钴-钴@碳纸电极(Co(OH)_(2)-Co@CP),并将其用于催化NaBH_(4)的电氧化反应。利用SEM、TEM、XRD及XPS等物理表征手段对所制备电极的形貌、组成、元素价态等进行了分析,并用CV及CA等电化学方法研究了所制备电极在碱性溶液中对Na BH_(4)的电氧化催化行为。结果表明,所制备电极对NaBH_(4)电氧化具有良好的催化活性。
Cobalt hydroxide-cobalt@carbon paper(Co(OH)_(2)-Co@CP)electrode is prepared through the electrodeposition and chemical reduction processes which make Co(OH)_(2)-Co nanoplates load on the surface of carbon paper.Then the electrode is used to catalyze the electrooxidation of NaBH_(4).Physical characterization methods including SEM,TEM,XRD and XPS are used to analyze the morphology,composition and element valence of the as-prepared electrode.Electrooxidation catalytic behavior of the electrode to NaBH_(4)in alkaline solution is studied by CV and CA electrochemical methods.The results indicate that the as-prepared electrode has a good catalytic activity in the electrooxidation of NaBH_(4).
