Recent advances in heterometallic polyoxotitanium clusters

Titanium‐Oxo Clusters with Bi‐ and Tridentate Organic Ligands: Gradual Evolution of the Structures from Small to Big

“…Heterometallic clusters will only be mentioned if their structures are related to that of their homometallic counterparts. The reason for doing so is that the presence of two (or more) metals results in a much greater variety of possible structures [10] which are therefore difficult to categorize.…”

Threefold Collaborative Stabilization of Ag14‐Nanorods by Hydrophobic Ti16‐Oxo Clusters and Alkynes: Designable Assembly and Solid‐State Optical‐Limiting Application

“…[18,19] In addition, to further promote the stabilities of noble metal NPs,they can be encapsulated into metal oxides shell to generate core-shell nanostructures,w hich can completely avoid migration and aggregation of noble metal NPs. [20,21] Correspondingly,a s molecular models of TiO 2 NPs, [22][23][24][25][26][27] atomic precise titaniumoxo clusters (TOC) can act as protecting shell to protect the sensitive Ag nanoclusters.T OC can be anionic and advantageous in stabilizing ac luster via balancing local positive charges of the noble metal cations and thus precluding their redox reactions.M eanwhile,a no uter TOCs hell could help control the size and shape of inner Ag cluster. Although one core-shell Ag 6 @Ti-oxo cluster was made by us, [28] the terminal sites of this Ag 6 are occupied by weak-bonding acetonitrile solvents,w hich are easily dissociated and sensitive to the moisture.Itisstill quite challenging to develop more efficient Ti-O protecting shell for increasing the ambient stability of encapsulated Ag nanoclusters.…”

Transition-metal doped titanium-oxo clusters with diverse structures and tunable photochemical properties

“…[22][23][24][25][26][27][28][29][30] Applying the heterometal-doping method to TOCs, a variety of heterometal doped TOCs have been constructed and show promising photocatalytic H 2 evolution under visible light irradiation. [31][32][33][34][35][36] Despite this, a systematic study on how different heterometals affect the structure, band gap and related photocatalysis performance of TOCs is still limited. 37,38 Indeed, this will not only give us more insight to understand the structure-property relationship but also provide instructive guidance to build high-performance TOC-based photoactive materials.…”
