| 英文摘要 | The development of new metal-organic frameworks (mofs) with dual functions of both water reduction and oxidation under visible-light irradiation is highly desirable for promising solar water splitting, but is not yet reported. herein, a cadmium-based mof (denoted as "cd-tbapy") single crystal with a 2d layered framework by employing 1,3,6,8-tetrakis(p-benzoic acid)pyrene (h(4)tbapy) as an organic linker is reported, which exhibits good visible-light absorption with edge of approximate to 600 nm. the mott-schottky (m-s) measurement and uv-vis analysis integrally reveal that the cd-tbapy is an n-type semiconductor with a bandgap of approximate to 2.15 ev whose conduction and valence band are estimated to be -0.05 and 2.10 ev, respectively. together with loading of pt or copi cocatalyst, the cd-tbapy is active for both water reduction and oxidation in the presence of scavengers under visible-light irradiation. especially, the optimized apparent quantum efficiency for o-2 evolution reaches 5.6% at 420 nm, much higher than that of previous mof-based photocatalysts reported so far. this is thought to be the first mof that functions as a photocatalyst for both water reduction and oxidation under visible light, demonstrating the intriguing future of mof materials in solar-to-chemical energy conversion. |
