生物炭因其潜在的环境效益而日益受到关注。除碳（C）外，硅（Si）是生物炭中的主要元素，具有丰富的前驱物来源和出色的性能。由于富含硅的生物炭（Sichar）的利用，以及Si在农业生产和环境修复中的重要作用，所以了解Sichar在Sichar中的环境影响是必不可少的。因此，本综述着重于Sichar中的碳硅耦合，并总结了有关Sichar中Si的表征，土壤改良，污染修复和C-Si耦合相互作用的高级研究。在了解了硅的含量，形态，种类和释放行为，环境对土壤硅平衡的影响，植物对硅的吸收后，总结了无机污染物（Al，As，Cd和Cr）的修复潜力。Sichar制备，污染修复和土壤固碳过程中突出了C-Si耦合作用。在自然，热解和地质过程中，C和Si的生物地球化学循环过程中来自生物质的C和Si的耦合关系可以获得农场，食品，燃料和资金的四个“ F”收益。为了更好地了解环境影响并最大程度地利用Sichar进行设计利用，需要对微生物进行更多的研究，并通过定量建模与不同离子进行更多的相互作用，这需要进行更多的研究。污染修复和土壤固碳。在自然，热解和地质过程中，C和Si的生物地球化学循环过程中来自生物质的C和Si的耦合关系可以获得农场，食品，燃料和资金的四个“ F”收益。为了更好地了解环境影响并最大程度地利用Sichar进行设计利用，需要对微生物进行更多的研究，并通过定量建模与不同离子进行更多的相互作用，这需要进行更多的研究。污染修复和土壤固碳。在自然，热解和地质过程中，C和Si的生物地球化学循环过程中来自生物质的C和Si的耦合关系可以获得农场，食品，燃料和资金的四个“ F”收益。为了更好地了解环境影响并最大程度地利用Sichar进行设计利用，需要对微生物进行更多的研究，并通过定量建模与不同离子进行更多的相互作用，这需要进行更多的研究。

Environmental Effects of Silicon within Biochar (Sichar) and Carbon-Silicon Coupling Mechanisms: A Critical Review.

Biochar is increasingly gaining attention for its potential environmental benefits. In addition to carbon (C), silicon (Si) is a major elemental component in biochar with abundant precursor sources and remarkable properties. Due to the abundance and utilization of silicon-rich biochar (Sichar), as well as the significant function of Si in agricultural production and environmental remediation, it is indispensable to understand the environmental effects of Si within Sichar. Therefore, this review focused on carbon-silicon coupling in Sichar and summarized the advanced studies on Si within Sichar regarding characterization, soil improvement, pollution remediation, and C-Si coupling interactions. After an understanding of Si content, morphology, species and releasing behaviors, the environmental effects on soil Si balance, the plant uptake of Si, and remediation potentials of inorganic pollutants (Al, As, Cd, and Cr) were summarized. The C-Si coupling interactions were highlighted in the processes of Sichar preparation, pollution remediation, and soil C sequestration. The coupling relationship of C and Si from biomass under natural, pyrolysis and geological processes for the biogeochemical cycling of C and Si can obtain four "F" benefits of farm, food, fuel, and finance. To better understand the environmental effects and maximize the benefits of the designed utilization of Sichar, more investigations are required with an extension to microbes and more interactions with different ions via quantitative modeling.
