摘　　要：通过水热合成法制备一种非贵金属铜负载氮掺杂生物质炭复合材料(Cu-NC),采用SEM、HRTEM、XRD、BET、XPS对样品进行表征.结果表明金属掺杂和高温水热处理后的样品具有更好的理化性质和催化性能.将催化剂应用于Friedl nder反应,反应体系以水或乙醇作为溶剂,在温和环境中、较短时间内获得产率在72%~98%的喹啉化合物,反应体系有效避免了保护气氛和碱性试剂的引入.催化材料在连续重复5次而催化活性无明显下降.此结果对柴胡药材渣基生物质炭材料的多样化合成与利用提供了思路,同时为廉价、高效和绿色的非贵金属负载氮掺杂生物质炭催化剂的制备与有机合成反应提供方法.A non-noble metal copper-supported nitrogen-doped biochar composite(Cu-NC)was prepared by hydrothermal synthesis.SEM,HRTEM,XRD,BET and XPS were used to characterize the samples.The results show that the samples after metal doping and high temperature hydrothermal treatment have better physicochemical properties and catalytic properties.When the catalyst is applied to the Friedl nder reaction,the reaction system uses water or ethanol as the solvent.Quinoline compounds with a yield ranging from 72%to 98%can be obtained in a mild environment within a relatively short period of time.The reaction system effectively avoids the introduction of a protective atmosphere and alkaline reagents.The catalytic activity of the catalytic material was not significantly decreased after five consecutive repetitions.This result provides an idea for the diversified synthesis and utilization of slag-based biochar materials from Bupleurum herbs,and provides a method for the preparation and organic synthesis of low-cost,efficient and green non-noble metal-supported nitrogen-doped biochar catalysts.
