Abstract

Carbon dots (CDs) derived from biomass have emerged as promising nanomaterials for agricultural applications due to their biocompatibility, tunable properties, and sustainability. The objective of this study was to develop a high-yield, eco-friendly synthesis method for biomass-derived CDs and evaluate their multifunctional performance in agriculture. Herein, we report a high-yield synthesis strategy for biomass-derived CDs using chrysanthemum, honeysuckle, and artemisinin as precursors, achieving yields of up to 79.5 %. The synthesized CDs using chrysanthemum, acrylamide, and initiator as precursors exhibit excellent water retention capabilities in soil, with a 14 % improvement compared to control groups after 24h, and demonstrate significant reactive oxygen species scavenging activity, including hydroxyl (·OH) and superoxide (·O₂⁻) radicals. Specifically, the hydroxyl radical scavenging efficiency reaches 63.2 % at a concentration of 200 μg/mL, with an IC₅₀ value of 77 μg/mL, and the superoxide radical scavenging efficiency reaches nearly 50 % at 0.8 mg/mL. Furthermore, foliar application of these CDs promotes the growth of Taraxacum officinale, enhancing root, stem, and leaf lengths by 8.7 %, 110 %, and 116 %, respectively. This work provides a scalable and eco-friendly approach to synthesizing functional CDs for sustainable agriculture.

生物质碳点高产合成促进蒲公英生长

源于生物质的碳点（cd）由于其生物相容性、可调特性和可持续性而成为农业应用的有前途的纳米材料。本研究的目的是开发一种高产、环保的生物质衍生CDs合成方法，并评估其在农业中的多功能性能。在此，我们报告了一种以菊花、金银花和青蒿素为前体的生物质衍生CDs的高产率合成策略，其产率高达79.5%。以菊花、丙烯酰胺和引发剂为前体合成的cd具有良好的土壤保水性，24h后比对照组提高14%，并具有显著的活性氧清除活性，包括羟基（·OH）和超氧（·O2−）自由基。其中，在浓度为200 μg/mL时，羟基自由基清除率达到63.2%，IC50值为77 μg/mL；在浓度为0.8 mg/mL时，超氧自由基清除率接近50%。此外，叶面施用这些cd可促进蒲公英的生长，使根、茎和叶的长度分别增加8.7%、110%和116%。这项工作为可持续农业合成功能性cd提供了一种可扩展和环保的方法。

期刊介绍： Biomass & Bioenergy is an international journal publishing original research papers and short communications, review articles and case studies on biological resources, chemical and biological processes, and biomass products for new renewable sources of energy and materials. The scope of the journal extends to the environmental, management and economic aspects of biomass and bioenergy. Key areas covered by the journal: • Biomass: sources, energy crop production processes, genetic improvements, composition. Please note that research on these biomass subjects must be linked directly to bioenergy generation. • Biological Residues: residues/rests from agricultural production, forestry and plantations (palm, sugar etc), processing industries, and municipal sources (MSW). Papers on the use of biomass residues through innovative processes/technological novelty and/or consideration of feedstock/system sustainability (or unsustainability) are welcomed. However waste treatment processes and pollution control or mitigation which are only tangentially related to bioenergy are not in the scope of the journal, as they are more suited to publications in the environmental arena. Papers that describe conventional waste streams (ie well described in existing literature) that do not empirically address ''new'' added value from the process are not suitable for submission to the journal. • Bioenergy Processes: fermentations, thermochemical conversions, liquid and gaseous fuels, and petrochemical substitutes • Bioenergy Utilization: direct combustion, gasification, electricity production, chemical processes, and by-product remediation • Biomass and the Environment: carbon cycle, the net energy efficiency of bioenergy systems, assessment of sustainability, and biodiversity issues.
