摘要

腐植酸（Humic acid， HA）是维持土壤肥力和健康的重要物质，在农业可持续发展和环境修复中具有重要作用。与自然过程相比，热液腐殖化（HTH）提供了在更短的时间内从生物质中生产HA类似物的优势，从而提高了碳效率。这种方法符合绿色化学原则，促进资源的可持续利用，同时最大限度地减少对环境的影响。然而，水热法生产HA的研究尚处于起步阶段，其条件、影响因素和转化机制尚不清楚。此外，热液HA的潜在应用尚未完全了解。本文通过近十年的研究，阐述了生物质水热转化为腐殖质酸的机理，并讨论了不同的HTH操作参数如反应时间、生物质组成、反应溶剂、反应温度等对腐殖质化过程的影响。鉴于目前缺乏对水热透明质酸应用的研究，我们通过探索水热透明质酸在农业、环境保护、功能材料制备和畜牧业等不同场景下的利用，展示了水热透明质酸的潜在应用和挑战。探讨了热液透明质酸商业化应用面临的挑战和研究方向，旨在为生物质热液转化透明质酸的研究提供参考。

Rapid humification of biomass via hydrothermal conversion: a comprehensive review

Humic acid (HA), a crucial substance for maintaining soil fertility and health, plays a vital role in sustainable agricultural development and environmental remediation. Hydrothermal humification (HTH) offers the advantage of producing HA analogues from biomass in a significantly shorter timeframe compared with natural processes, thereby enhancing carbon efficiency. This approach aligns with green chemistry principles by promoting the sustainable utilization of resources while minimizing environmental impacts. However, research on the hydrothermal production of HA is still in its early stages, with the underlying conditions, influencing factors, and conversion mechanisms remaining unclear. Furthermore, the potential applications of hydrothermal HA are not yet fully understood. Drawing from nearly a decade of research, this article addresses the mechanism of hydrothermal conversion of biomass into HA and discusses the impacts of diverse HTH operating parameters such as reaction time, biomass composition, reaction solvent, and reaction temperature on the humification process. Given the current lack of research on the applications of hydrothermal HA, we demonstrated the potential applications and challenges of hydrothermal HA by exploring the use of HA from various other sources in diverse scenarios, including agriculture, environmental protection, functional material preparation and animal husbandry. Furthermore, the challenges and research directions for the commercial application of hydrothermal HA are discussed, aiming to provide a reference for studies on HA derived from biomass via hydrothermal conversion.

期刊介绍： Green Chemistry is a journal that provides a unique forum for the publication of innovative research on the development of alternative green and sustainable technologies. The scope of Green Chemistry is based on the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998), which defines green chemistry as the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green Chemistry aims to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. The journal welcomes submissions on all aspects of research relating to this endeavor and publishes original and significant cutting-edge research that is likely to be of wide general appeal. For a work to be published, it must present a significant advance in green chemistry, including a comparison with existing methods and a demonstration of advantages over those methods.
