چکیده
A large manganese-doped polyoxotitanate nanocluster Ti28MnO38(OEt)40H2, has been synthesized solvothermally. Its structure is arranged around the four-coordinate Mn(2+) dopant atom in a Keggin-type structure. A significant reduction of the band gap relative to that of undoped polyoxotitanate clusters is observed.

A manganese-doped polymeric framework of polyoxotitanate nanoclusters with a narrow band gap.
A three-dimensional coordination polymer based on a manganese-doped polyoxotitanate nanocluster, {Ti13Mn4O16[MeC(CH2O)3]4(OEt)12Br4}∞, has been synthesized under solvothermal conditions. It is the first framework of doped polyoxotitanate nanoclusters reported in the literature. Compared with anatase, its band gap is reduced from 3.19 to 2.57 eV.

The novel heterometallic polyoxotitanate cage [Ti18MnO30(OEt)20(MnPhen)3] (1), obtained by solvothermal reaction of Ti(OEt)4 with Mn(AcO)3·(H2O)2 and 1,10-phenanthroline (Phen) in EtOH, has a C3 symmetric core structure containing an interstitial tetrahedral Mn(II) ion and is surrounded by three Mn(II)(Phen) fragments. The molecular structure is retained in thin film electrodes of 1 deposited b...
متن کاملGeneral synthesis of manganese-doped II-VI and III-V semiconductor nanowires.
A general approach for the synthesis of manganese-doped II-VI and III-V nanowires based on metal nanocluster-catalyzed chemical vapor deposition has been developed. High-resolution transmission electron microscopy and energy-dispersive X-ray spectroscopy studies of Mn-doped CdS, ZnS, and GaN nanowires demonstrate that the nanowires are single-crystal structures and homogeneously doped with cont...
متن کاملPhotocatalytic degradation of an azo textile dye with manganese-doped ZnO nanoparticles coated on glass
Mn doped ZnO nanocomposite thin film coated on glass by a simple spin-coating method was used to degrade an azo textile dye from aqueous environment. Mn doped ZnO nanocomposite thin film was characterized by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM). The photo-reduction activity of photocatalyst was evaluated using an azo textile dye as organic contaminant irradiat...
