摘    要:通过Pd Cl42-与Co之间发生简单的置换反应,在表面活性剂PVP的作用下,成功地制备出由3 nm的Pd纳米粒子组成的空心结构Pd纳米球结构,将其命名为Pd-NS。随后,以石墨烯(GN)作为载体,将Pd-NS负载在GN的表面制备了Pd-NS/GN催化剂。在甲酸电氧化催化反应中,Pd-NS/GN催化剂表现出较大的电化学比表面积、良好的电催化性能以及较高的稳定性。

关 键 词:空心结构  Pd纳米粒子  石墨烯  电催化性能  甲酸燃料电池

Abstract:An efficient synthetic strategy have been developed, which is based on the simple substitution reaction between PdCl42- and Co. Under the action of surfactant PVP, the hollow structure of Pd catalyst was prepared successfully. Subsequently, graphene was used as the support. After loading the Pd-NS on the surface of graphene, the Pd-NS/GN catalyst was prepared. For the electrooxidation of formic acid, Pd-NS/ GN catalyst showed a larger electrochemical specific surface area, good electrical catalytic performance and high stability.
Keywords:hollow structure  Pd nanoparticales  grapheme  electro-catalytic property  formic acid fuel cells
