| 英文摘要 | Phase isomerism is a common and important phenomenon in inorganic materials, but the molecular isomerism of their nanocluster models is still rare. in this work, we report the first pair of isomeric titanium-oxo clusters. through combining pentagonal {ti(ti-5)} building units in corner-sharing or edge-sharing forms, the two obtained ti-20-oxo clusters take vertical and horizontal core configurations, respectively, which are both functionalized by the same organic ligands. more interestingly, the vertical type ti-20-oxo core contains an identical {ti8o14} moiety as anatase, making it the first molecular model of anatase tio2. as a result, the vertical type cluster exhibits better photocatalytic h-2 evolution activity, higher photocurrent response and faster charge transfer to external acceptors than its horizontal isomer. thus, this work provides a cluster isomer method to understand the structure-property relationship of import titanium oxide materials. |
