英文摘要: Hierarchical Co nanoflowers composed of nanorods were fabricated through a simple solvothermal synthesis in polyol using Ru as the heterogeneous nucleation agent and hexadecylamine as the structure-directing agent. The solid cobalt alkoxide that is produced in the primary stage mediates the growth rate of the Co nanoflowers, which follow a hierarchical growth mode. The core is initially formed, followed by anisotropic growth into a wheat fringe that further grows to nanoflower. The sizes of the nanoflowers and the petals can be simply adjusted by varying the concentration of hexadecylamine. Typically, well-defined nanoflowers of about 500 nm having petals with lengths of about 500 nm and diameters of 50 nm were obtained. The Co nanoflowers showed quite promising catalytic performance in the hydrogenolysis of glycerol to propylene glycol, demonstrating a potential application in heterogeneous catalysis.
