Abstract
The energy development based on fossil fuels is creating major problems because the sweltering of fossil fuels leads to the generation of gases linked to global warming. The reduction of these natural resources is also an important issue of concern which has stimulated scientists to search for green and economic energy production method to meet growing demands. Microbial fuel cells (MFCs) have attracted great scientific attention because they can produce clean energy from a variety of waste materials using microorganisms as the catalyst. The controlling factor for power generation in MFCs depends on the design and efficacy of the electrode material, which provides the active sites for the cathodic oxygen reduction reaction. Most electrodes used in MFCs to enhance the performance were generally platinum-based, which has limited their large scale applications. Therefore, it is important to fabricate efficient and economically viable cathodes for MFCs using alternative inexpensive conductive materials which provide the catalyst with improved kinetics oxygen reduction reaction at the working cathode. In the present study, a fibrous PANI-MnO2 nanocomposite was prepared using a scalable in situ chemical oxidative polymerization method. The electrochemical capacitive behavior of the as-synthesized fibrous PANI-MnO2 nanocomposite was evaluated further by cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD) measurements. The fibrous PANI-MnO2 nanocomposite showed a better electrochemical specific capacitance with excellent cyclic stability. In addition, the fibrous PANI-MnO2 nanocomposite was also assessed as a cathode catalyst for improved power generation in MFCs and showed much better performance than either PANI or plain carbon paper.
