| 英文摘要 | Novel urchin-like pd@cuo-pd yolk-shell nanostructures are synthesized through subsequent oxidation of pd@cu2o truncated octahedron core-shell precursors with a pdcl42- aqueous solution. the permeable hierarchical cuo shells are constructed by a radially standing 1d single-crystalline nanothorn with pd nanoparticles. the pd nanocube cores are encapsulated and confined in the void space of the urchin-like shells. the urchin-like yolk-shell pd@cuo-pd nanostructures demonstrate excellent electrocatalytic activity and selectivity for glucose oxidation. enzyme-free glucose biosensors based on the urchin-like yolk-shell pd@cuo-pd electrocatalysts display a higher sensitivity (665.9 mu a cm(-2) mm(-1)) than those of the cuo nanoparticles (455.8 mu a cm (2) mm (1)), cu2o nanoparticles (220.4 mu a cm (2) mm (1)), pd@cu2o truncated octahedra (179.1 mu a cm(-2) mm(-1)), pd mixtures (65.5 mu a cm(-2) mm(-1)) and pd nanocubes (1.42 mu a cm(-2) mm(-1)). the outstanding electrocatalytic performance of the urchin-like pd@cuo-pd yolk-shell nanostructures might be ascribed to two reasons: the unique hierarchical yolk-shell structures provide highly exposed active sites and act as an individualized nanoreactor to enhance the mass diffusion and transport of reactants at the electrode/electrolyte interface. moreover, the nanocomposite of metal oxide semiconductor cuo and noble metal pd would result in a synergetic effect to improve the electrocatalysis. |
