Atomically Precise Titanium–Oxo Nanotube with Selective Water Adsorption and Semiconductive Behaviors

Rational Preparation of Atomically Precise Non-Alkyl Tin-Oxo Clusters with Theoretical to Experimental Insights into Electrocatalytic CO 2 Reduction Applications

“…[7][8][9][10] Except for the common oxo bridges, metal-oxo clusters usually present different terminal functionalization groups, which are highly dependent on the intrinsic characteristic of metal centers. [11][12] Oxo clusters of transition metals (typically as polyoxometalates), for instance easily present O-donor terminal groups but difficult to be functionalized by N-donor groups, not mention to alkyl ligands. 7,[13][14] Whilst, oxo clusters of main group metals like Sn, Sb, Te and others often show alkyl type end groups.…”

An Unprecedented Chalcogenide-cluster-based Semiconducting Nanotube Array with Oriented Photoconductive Behavior

“…Over the past three decades, one-dimensional (1D) hollow tubular nanomaterials have long been the focus of considerable interest in the physics, chemistry, and materials communities because of their unique physical and chemical properties, as well as their diverse potential applications since the discovery of carbon nanotubes (CNTs) by Iijima in 1991. [1][2][3][4][5][6][7][8] To date, several multifarious nanotubular architectures with pure inorganic or inorganic-organic hybrid or pure organic components as the nanotube skeleton have been synthesized and applied in various elds, such as catalysis, 9, 10 molecular capillaries, 11 energy storage, 12,13 and biological models. 14,15 Among the various nanotubular materials, robust inorganic nanotubes with high thermal and chemical stabilities are considered extremely promising for a wide range of interesting potential properties and applications, and therefore, these materials have attracted a great deal of scienti c attention.…”

“…(see Supplementary Files) Generally, inorganic nanotubes are formed by rolling up exfoliated two-dimensional (2D) at sheets of corresponding lamellar materials under special non-equilibrium conditions (chemical vapor deposition, ash evaporation and discharge evaporation) 16,17 or constructed through a bottom-up approach from basic inorganic elements. 6,7,[16][17][18][19][20][21][22][23][24][25] The nanotubes fabricated via the rolling-up approach are usually in the form of fully or partially disordered arrays with large size distributions (Scheme 1a), which may require additional puri cation steps to avoid affecting their applications. 6,7,19 In contrast, high-quality nanotubes, synthesized using a bottom-up strategy and possessing an atomically precise structure and uniform size, are highly desirable for understanding structure-property relationships and future applications.…”
