摘　　要：以碳纤维纸为基底,采用电沉积法分步合成了纳米铂-铱(Pt-Ir)粒子。采用扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X射线能谱(EDS)等物理表征手段对电催化剂的形貌结构及元素组成进行了研究。从生物质来源的乙酰丙酸(LA)出发,以纳米铂-铱粒子为电催化剂,在甲醇相体系中电催化合成2,7-辛二酮。同时,实验结果证明铱元素的引入增强了纳米铂粒子的电化学活性,并降低了铂的使用量,节约了成本。Nano-sized Pt-Ir particle was synthesized by electrodeposition method with carbon fiber paper as the substrate.The morphology,structure and element composition of the electrocatalyst were studied by scanning electron microscope(SEM),transmission electron microscope(TEM),X-ray energy spectrum analysis(EDS)and other physical characterization methods.Starting with the biomass downstream product levulinic acid,2,7-octanedione was synthesized in methanol system with the nano-sized Pt-Ir particle as electrocatalyst.Meanwhile,the experimental results showed that the introduction of Ir improved the electrochemical activity of Pt particles and reduced the amount of Pt and the cost.
