厌氧消化技术对于生物能源回收和有机废物管理至关重要。同时，常常遇到有机物消化率低、有毒物质抑制等挑战，导致生物甲烷收率低。生物炭最近被用于厌氧消化，以减轻毒性抑制，提高厌氧消化过程的稳定性，并提高甲烷产量。然而，生物炭的实际应用受到限制，因为原始生物炭的性质显着影响其在厌氧消化中的应用。尽管许多研究侧重于了解原始生物炭的基本性质和功能化，但对功能性生物炭的应用以及原始生物炭的关键性质对厌氧消化的影响的评论很少。该综述系统地综述了功能性生物炭在厌氧消化中的功能化策略、关键性能和应用。综述了决定生物炭作用的性质，总结比较了功能性生物炭的合成方法，探讨了功能性生物炭的作用机理，综述了影响功能性生物炭功能的因素。该综述提供了对厌氧消化过程中功能性生物炭的全面了解，这将有助于工程生物炭的开发和应用。

Functional biochar in enhanced anaerobic digestion: Synthesis, performances, and mechanisms

Anaerobic digestion technology is crucial in bioenergy recovery and organic waste management. At the same time, it often encounters challenges such as low organic digestibility and inhibition of toxic substances, resulting in low biomethane yields. Biochar has recently been used in anaerobic digestion to alleviate toxicity inhibition, improve the stability of anaerobic digestion processes, and increase methane yields. However, the practical application of biochar is limited, for the properties of pristine biochar significantly affect its application in anaerobic digestion. Although much research focuses on understanding original biochar's fundamental properties and functionalization, there are few reviews on the applications of functional biochar and the effects of critical properties of pristine biochar on anaerobic digestion. This review systematically reviewed functionalization strategies, key performances, and applications of functional biochar in anaerobic digestion. The properties determining the role of biochar were reviewed, the synthesis methods of functional biochar were summarized and compared, the mechanism of functional biochar was discussed, and the factors affecting the function of functional biochar were reviewed. This review provided a comprehensive understanding of functional biochar in anaerobic digestion processes, which would be helpful for the development and applications of engineered biochar.
