[New iron-porphyrin/vanadium-substituted polyoxometalate catalyst: synthesis, characterization and catalytic activity].

A new kind of iron-porphyrin/vanadium-substituted polyoxometalate coordination compound was synthesized by the ion exchange reaction of FeTTMAPPI and H5PMo10V2o40 in solution. The new catalyst was characterized by IR spectrometry and UV-Vis spectrometry. As an excellent catalyst, its effects on benzene hydroxylation and catalytic capabilities were studied with H2O2 solution as the oxidant.

[Manganeseporphyrin/vanadium-substituted polyoxometalate new coordination compound: synthesis, characterization and catalytic activity].

A new kind of manganeseporphyrin/vanadium-substituted polyoxometalate coordination compound was synthesized by meso-tetrakis(4-trimethylamidiophenyl) manganeseporphyrin and vanadium-substituted polyoxometalate H5 PMo10 V2O4 reacting in water solution at room temperature, and its structures were studied by IR spectrometry and UV-Vis spectrometry. The results show that metalloporphyrin ring structure and polyoxometalate cage structure still exist in the coordination compound, and these two parts connect with each other by chemical bond. As an excellent catalyst, its effects on benzene hydroxylation and catalytic capabilities were studied with H2O2 solution as an oxidant under mild reaction condition, meanwhile the catalytic active centre in the benzene hydroxylation reaction was discussed.

[Preparation and structural characterization of ZnTHPP/TiO2 hybrid material].

Using sol-gel method to make tetra-meso (hydroxylphenyl) zinc porphyrin (ZnTHPP) trapped in inorganic networks of TiO2, a new organic/inorganic hybrid material was prepared. The structures and morphology of this material were characterized by thermogravimetric analyses (TGA), infrared spectrum (FTIR), UV-Vis spectrum (UV), diffuse reflectance spectroscopy (DRS), and scanning electron microscopy (SEM), indicating that ZnTHPP/TiO2 hybrid material possessed excellent thermostability, and ZnTHPP was trapped in TiO2 network with chemical bonds. In addition, ZnTHPP embedding can enlarge the absorption range of light for TiO2 effectivelly.
