Abstract Phase isomerism is a common and important phenomenon in inorganic materials, but the molecular of their nanocluster models still rare. In this work, we report first pair isomeric titanium‐oxo clusters. Through combining pentagonal {Ti(Ti 5 )} building units corner‐sharing or edge‐sharing forms, two obtained Ti 20 ‐oxo clusters take vertical horizontal core configurations, respectively, which are both functionalized by same organic ligands. More interestingly, type contains an...

Polyoxo-titanium clusters (PTCs) are applied to construct highly efficient ternary PTC/CdS/MIL-101 visible-light-range H2 -evolution photocatalysts. The application of PTCs not only increases the photocatalytic activities but also provides a molecular tool tune them.

ConspectusAtomically precise titanium-oxo clusters (TOCs) are the structure and reactivity model compounds of technically important TiO2 materials, which could help build structure-property relationships achieve property modulation at molecular level. However, traditional formation TOCs has relied on poorly controllable hydrolysis titanium alkoxide in solvent for a long time, limiting development TOC structural chemistry to great extent. In addition, easily hydrolyzable alkoxy groups would...

The construction of biomimetic cluster catalysts with metalloenzyme-like active sites may open an avenue for the challenging transformation greenhouse gases (e.g., CO2) to high-value chemicals. Cu-enzymes occur in all three biological kingdoms, CuZ clusters serving as representative reaction that catalyze transformations. However, artificial Cu analogous structures and high stability are still rare. In this work, we have successfully adopted a Ti9-oxo nanoring inorganic templating scaffold...

MOFs based on high-nuclear clusters as building blocks are specifically attractive but generally unsuitable for efficient Xe/Kr selective separation. In this study, a rare alkynyl Cu12 cluster-based framework with 1D microchannel (Cu12) has been successfully developed. Furthermore, the presence of rich tert-butyl and benzene groups within channels creates significant differentiation in adsorption binding affinity Xe Kr, enabling to efficiently separate from Kr. Significantly, not only...
