Solvent-free, visible-light photocatalytic alcohol oxidations applying an organic photocatalyst

A method for the solvent-free photocatalytic conversion of solid and liquid substrates was developed, using a novel rod mill apparatus. In this setup, thin liquid films are realized which is crucial for an effective photocatalytic conversion due to the low penetration depth of light in heterogeneous systems. Several benzylic alcohols were oxidized with riboflavin tetraacetate as photocatalyst u...

Solvent free permanganate oxidations

The oxidations of organic compounds by permanganate under solvent free conditions have been studied. Thiols and primary aromatic amines undergo oxidative coupling reactions to give disulfides and diazenes, respectively, sulfides are oxidized to sulfones, primary and secondary alcohols are converted to aldehydes and ketones, 1,4-diols and cyclic ethers give lactones and arenes are oxidized to th...

Enhanced photocatalytic oxygen evolution over Mo-doped Ca2NiWO6 perovskite photocatalyst under visible light irradiation

Ying Luo, Jiawei Xue, Xiaodi Zhu, Jose Daniel, Xiang Gao, Song Sun,* Chen Gao* and Jun Bao* A series of Mo-doped Ca2NiWO6 (Ca2NiW1 xMoxO6, x1⁄4 0–0.05) samples were synthesized by a solid-state reaction. The physical and optical properties of these photocatalysts were characterized by X-ray diffraction, X-ray absorption fine structure, UV-visible diffuse reflectance spectra, and the band struct...

A new Bi-based visible-light-sensitive photocatalyst BiLa1.4Ca0.6O4.2: crystal structure, optical property and photocatalytic activity.

A new compound of BiLa1.4Ca0.6O4.2 is synthesized through solid state reaction, where the Ca substitutes, in part, the La site in a stable BiLa2O4.5 phase. The structure of the BiLa1.4Ca0.6O4.2 crystallizes in space group R3mH with a hexagonal lattice constants of a = 3.893(1) Å, c = 9.891(1) Å. Its optical absorption edge is about 2.05 eV, which just spans the visible light region. The photoca...
