| 摘要: 通过PdCl42-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. |

| 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. |
