Graphene-modified materials have captured increasing attention for energy applications due to their superior physical and chemical properties, which can significantly enhance the electricity generation performance of microbial fuel cells (MFC). In this review, several typical synthesis methods of graphene-modified electrodes, such as graphite oxide reduction methods, self-assembly methods, and chemical vapor deposition, are summarized. According to the different functions of the graphene-modified materials in the MFC anode and cathode chambers, a series of design concepts for MFC electrodes are assembled, e.g., enhancing the biocompatibility and improving the extracellular electron transfer efficiency for anode electrodes and increasing the active sites and strengthening the reduction pathway for cathode electrodes. In spite of the challenges of MFC electrodes, graphene-modified electrodes are promising for MFC development to address the reduction in efficiency brought about by organic waste by converting it into electrical energy.
由于其优异的物理和化学性质，石墨烯改性材料在能源应用中受到越来越多的关注，这可以显著提高微生物燃料电池（MFC）的发电性能。在这篇综述中，总结了几种典型的石墨烯改性电极的合成方法，如氧化石墨还原法、自组装法和化学气相沉积法。根据石墨烯改性材料在MFC阳极和阴极室中的不同功能，组装了一系列MFC电极的设计理念，例如，提高阳极电极的生物相容性和改善细胞外电子转移效率，以及增加阴极电极的活性位点和强化还原途径。尽管MFC电极存在挑战，但石墨烯改性电极对于MFC的发展具有前景，可通过将有机废物转化为电能来解决其效率降低的问题。
