In this study, carbonized waste tires were directly used as a high-performance anode material in microbial fuel cells (MFCs). The effect of the pyrolysis temperature used for waste tire carbonization on the current output performance was investigated to determine the optimal pyrolysis temperature. Thermal gravimetric analysis/differential scanning calorimetry showed that tire carbonization started at 200°C and ended at about 500°C; the weight loss was about 64%. When used in an MFC, the electrode obtained from waste tires carbonized at 800°C gave a current density of 23.1±1.4Am, which is much higher than that achieved with traditional graphite felt anodes (5.5±0.1Am). The results of this study will be useful in optimizing the design of carbonized waste tire anodes for enhancing MFC performances and will alleviate the environmental problems caused by waste tires.
在这项研究中,碳化废轮胎被直接用作微生物燃料电池 (MFC) 中的高性能阳极材料。考察了废轮胎碳化的热解温度对电流输出性能的影响,以确定最佳的热解温度。热重分析/差示扫描量热法表明,轮胎碳化始于 200°C,大约在 500°C 结束;重量损失约为 64%。在 MFC 中使用时,在 800°C 下碳化的废轮胎制成的电极的电流密度为 23.1±1.4Am,远高于传统石墨毡阳极(5.5±0.1Am)的电流密度。这项研究的结果将有助于优化碳化废轮胎阳极的设计,以提高 MFC 的性能,并减轻废轮胎造成的环境问题。
