Co3O4@CeO2 core@shell nanowires have been successfully prepared in mass production by thermal decomposition of Co(CO3)0.5(OH)﹞0.11H2O@CeO2 precursors. The successful fabrication of the core@shell structures leads to remarkably improved catalytic activity and stability of Co3O4. The best sample can catalyze 100% CO conversion at a temperature as low as 160 ∼C. Detailed study reveals that CO oxidation possibly takes place at the interface of Co3O4 and CeO2, demonstrating obvious synergistic effects between the two components.

The hierarchical TiO2 photocatalysts with one-dimensional hetero- junction have been synthesized for the first time. This kind of one-dimensional heterojunction is conducive to the separation of carrier andincreasement of quantum efficiency. In both of photocatalytic oxidation and reduction reactions, the photocatalysts exhibit better performance.

A method for the synthesis of octahedral Pd nanocrystals, by manipulating the kinetics of atomic addition, has been developed. The atomic addition preferentially occurred on higher-energy surfaces when very low atomic concentrations were maintained, which produced Pd octahedrons with sizes as small as 5 nm. This perfect size and facet control increased the catalytic efficiency of Heck coupling reactions.
