A visible-light photocatalytic N-radical cascade of hydrazones for the synthesis of dihydropyrazole-fused benzosultams.
An efficient visible light photocatalytic and external oxidant-free N-radical 5-exo cyclization/addition/aromatization cascade of β,γ-unsaturated hydrazones is described, which provides a practical route to various biologically interesting dihydropyrazole-fused benzosultams in satisfactory yields.
متن کاملPreparation and Visible-light Photocatalytic Activity of Pt/TiO2-xNy
Pt/TiO2-xNy film has been synthesized successfully through the sol-gel method and spin coating method. The roughness and absorption wavelength were analyzed by atomic force microscopy (AFM) and ultraviolet and visible spectrophotometer(UV-vis). X-ray photoelectron spectroscopy(XPS) showed that the elements contain Pt, N, Ti and O. Moreover, the photocatalytic degradation of methylene blue demon...
متن کاملHeterojunctions of p-BiOI Nanosheets/n-TiO₂ Nanofibers: Preparation and Enhanced Visible-Light Photocatalytic Activity.
p-BiOI nanosheets/n-TiO₂ nanofibers (p-BiOI/n-TiO₂ NFs) have been facilely prepared via the electrospinning technique combining successive ionic layer adsorption and reaction (SILAR). Dense BiOI nanosheets with good crystalline and width about 500 nm were uniformly assembled on TiO₂ nanofibers at room temperature. The amount of the heterojunctions and the specific surface area were well control...

متن کاملVisible light mediated photocatalytic activity of cobalt doped Bi2O3 nanoparticles
Herein, we suggest a novel chemical precipitation method to prepare different concentrations (0.05–0.25 M) of cobalt doped Bi2O3 nanoparticles. The prepared products exhibit excellent structural and optical properties. The influence of doping on the morphology of Bi2O3 was analyzed by FE-SEM and confirmed by HR-TEM. Furthermore, the photocatalytic activities of the samples were studied in the d...
