摘要
铅纳米线作为一种新型纳米材料,其物理化学性质独特,在生物医学、材料科学、能源与环境科学等领域具重要应用价值。采用溶剂热法,以乙二醇为溶剂,系统研究溶剂含水量对铅纳米结构形貌影响。通过镁条蒸馏及分子筛两种方法对乙二醇进行除水处理,制备不同含水量的乙二醇溶剂体系,并与乙酸铅反应合成铅纳米材料。扫描电子显微镜(SEM)表征结果表明,溶剂含水量显著影响铅纳米结构形貌;X射线衍射(XRD)分析证实所得产物为纯相铅。此外,研究还探讨了石油加工与纳米材料合成的协同关系:一方面,纳米材料可为石油加工提供高效绿色催化剂;另一方面,重质/劣质油可作为制备纳米材料的原料,这为石油资源的高值化利用及低碳化加工提供新思路。
Lead nanowires,as a novel nanomaterial,have unique physicochemical properties distinct from their bulk counterparts,demonstrating significant application potential in biomedical fields,materials science,energy and environmental sciences.This study employed a solvothermal method using ethylene glycol as solvent to systematically investigate the effect of solvent water content on the morphology of lead nanostructures.Through two dehydration approaches-magnesium strip distillation and molecular sieves-ethylene glycol solvent systems with varying water contents were prepared and reacted with lead acetate to synthesize lead nanomaterials.Scanning electron microscopy(SEM)characterization revealed that solvent water content significantly influenced the morphology of lead nanostructures,while X-ray diffraction(XRD)analysis confirmed the obtained products as pure-phase lead.Furthermore,the study explored the synergistic relationship between petroleum processing and nanomaterial synthesis:nanomaterials can serve as efficient green catalysts for petroleum refining,while heavy/inferior oils may act as raw materials for nanomaterial production,offering novel perspectives for high-value utilization and low-carbon processing of petroleum resources.
