Time-Resolved Spectroscopy. In their Communication (e202307178), Andreas Gansäuer, Peter Vöhringer et al. report time-resolved fluorescence and ultrafast mid-infrared spectroscopies to study the primary events of entry into a sustainable photoredox-catalytic cycle utilizing titanium(IV) photocatalyst.

nano-sized titanium dioxide tio2 powder was prepared by new wet chemical route from its precursor titanium (iv) chloride (ticl4) as precursor with isopropoxy alcohol in presence of nitric acid under ambient condition. their morphologies, phase compositions and components of the tio2 nanoparticles were characterized by transmission electron microscopy (tem), field emission scanning electron micr...

titanium (ti) is a relatively abundant element that has found growing applications in medical science and recently some of ti compounds are introduced as anticancer drugs. in spite of very limited data which exist on the ti metabolism, some proteins might be involved in the mechanism of action of ti. up to our knowledge, there is not any report in the literature concerning binding of ti to apol...

Titanium(IV) oxide, titania, photocatalyst particles were prepared from titanium alkoxide in the presence of several kinds ionic liquids, and it was clarified that a group samples exhibited photocatalytic activity for phenol degradation under irradiation light wavelength >400 nm higher than those other samples. Although conventional structural analytical results could not be related to activity...

The known properties of alkyl and aryl derivatives of transition elements are reviewed, with particular attention to binary compounds of this type. Factors contributing to thermal stability of metal—carbon a-bonds are discussed and new contributions are presented dealing with: (1) chemistry of titanium(Iv) and titaniurn(n); (ii) metal—carbon bonds in N,N'-ethylenebis(salicylideneiminato) comple...

The Baylis-Hillman reactions of various aryl aldehydes with methyl vinyl ketone at temperatures below -20C using Lewis acids such as titanium (IV) chloride, boron (III) chloride or zirconium (IV) chloride in the presence of a catalytic amount of selected amines used as a Lewis bases afford the chlorinated compounds 1 as the major product in very high yields. Acrylonitrile can also undergo the s...

A bio-based magnetic nano-catalyst (Fe3O4@nano-dextrin/Ti(IV)) was synthesized via the preparation of Fe3O4@nano-dextrinas magnetic support and then its treatment with titanium tetrachloride (TiCl4). The properties of this catalyst were characterized by different kinds of techniques such as FT-IR, FESEM, TEM, ICP, XRF, VSM and TGA....
