Carbon-based materials such as graphite, graphene, biochar, activated carbon, carbon cloth and nano-tube, and maghemite and magnetite carbons are capable for adsorbing chemicals onto their surfaces. Currently, this review is to highlight the relevance of carbons in enhancing hydrogen or methane production. Some key roles of carbons in improving cell growth, enrichment and activity, and accelerating their co-metabolisms were elaborated with regard to their effects on syntrophic communities, interspecies electron transfer, buffering capacity, biogas upgrading, and fertilizer nutrient retention and land application. Carbons can serve as a habitation for microbial immobilization, and a provision for bioelectrical connections among cells, and provide some essential elements for anaerobes. Besides, an outlook on the possible options towards the large scale and improvement solutions has been provided. Further studies in this area could be encouraged to intend and operate continuous mode by designing carbon-amended bioreactor with stability and reliability.
碳基材料，如石墨、石墨烯、生物炭、活性炭、碳纤维和纳米管、磁赤铁矿和磁铁矿碳，都能够将化学物质吸附到其表面。目前，本综述旨在强调碳在促进氢气或甲烷生产方面的相关性。本文详细阐述了碳在提高细胞生长、富集和活性以及加速共代谢方面的一些关键作用，包括对同养群落、种间电子转移、缓冲能力、沼气升级以及肥料养分保留和土地应用的影响。碳可以作为微生物固定化的栖息地，为细胞之间的生物电连接提供条件，并为厌氧菌提供一些必需元素。此外，还提供了针对大规模和改进解决方案的可能选择的展望。鼓励在该领域进行进一步研究，通过设计具有稳定性和可靠性的添加碳的生物反应器，以实现连续模式的预期和操作。
