Abstract
Pristine carbon felt is activated and functionalized through a cost-effective, eco-friendly method by immersion in a commercial 5 wt% hypochlorite solution. Electrochemical analyses, including cyclic voltammetry, galvanostatic charge–discharge tests, capacitance, and impedance measurements at 1 Hz, reveal that the activated carbon felt exhibits a twenty-fold enhancement in performance compared to its pristine counterpart. Pristine and activated carbon felt are characterized using scanning electron microscopy, X-ray photoelectron spectroscopy, contact angle measurement, and water uptake tests confirming the significant changes in material properties. To further validate the activation process, polypyrrole is galvanostatically electrodeposited on both pristine and activated carbon felts, with their electrochemical behaviors serving as a model system. The findings indicate a substantial improvement of activated carbon felt, with fourth times increase in capacity, highlighting the potential for advanced applications.
期刊介绍:
The Journal of Electroanalytical Chemistry is the foremost international journal devoted to the interdisciplinary subject of electrochemistry in all its aspects, theoretical as well as applied.
Electrochemistry is a wide ranging area that is in a state of continuous evolution. Rather than compiling a long list of topics covered by the Journal, the editors would like to draw particular attention to the key issues of novelty, topicality and quality. Papers should present new and interesting electrochemical science in a way that is accessible to the reader. The presentation and discussion should be at a level that is consistent with the international status of the Journal. Reports describing the application of well-established techniques to problems that are essentially technical will not be accepted. Similarly, papers that report observations but fail to provide adequate interpretation will be rejected by the Editors. Papers dealing with technical electrochemistry should be submitted to other specialist journals unless the authors can show that their work provides substantially new insights into electrochemical processes.
