Dibenzo-fused five-membered heteroaromatic compounds, including dibenzofuran, carbazole, and dibenzothiophene, are fundamental structural units in various important polycyclic compounds. The intramolecular C-H/C-H biaryl coupling of diaryl (thio)ethers amines based on palladium(II) catalysis under oxidative conditions is known to be one the most effective, step-economic methods for their constr...

Re/Pd-TiO2/SiO2 aerogel catalysts were synthesized by using a sol-gel method and supercritical drying in excess solvent investigated the reaction of hydrodesulphurisation (HDS) dibenzothiophene (DBT) 4,6-dimethyl (4,6-DMDBT). Both Re/Pd catalysts, obtained with without use mesitylene synthesis step, have shown increased conversions up to 70 % desulphurization 4,6-DMDBT, when compared convention...

A novel AgO/ZnO/HY-zeolite bimetallic nanocatalyst was designed and synthesized by an impregnation method. The purpose of this to remove dibenzothiophene as the primary sulfur content from a model light gasoil in catalytic oxidative desulfurization (ODS) process. characteristics were determined Fourier transform IR spectroscopy, Brunauer-Emmett-Teller analysis, scanning electron microscopy, X-r...

Microbial cells of Pseudomonas delafieldii were coated with magnetic Fe3O4 nanoparticles and then immobilized by external application of a magnetic field. Magnetic Fe3O4 nanoparticles were synthesized by a coprecipitation method followed by modification with ammonium oleate. The surface-modified Fe3O4 nanoparticles were monodispersed in an aqueous solution and did not precipitate in over 18 mon...
