A hydrophobic-bentonite catalyst (cetyltrimethyl ammonium bromide-bentonite) has been used as a very mild, neutral, eco-friendly, reusable, non-toxic, low-cost and easily available catalyst. It was prepared by replacing the exchangeable Na+ cations of a homoionic Na–bentonite with cetyltrimethyl ammonium bromide (CTMAB) cations. The catalyst was characterized by XRD, BET and SEM. The BET data and XRD […]
In this investigation, a fluidized bed photocatalytic reaction system was designed to eliminate emerging contaminants: acetaminophen and pyridine in water. Titanium dioxide (TiO2) doped with aluminum (Al3+) using the photo-deposition technique was used as a catalyst and supported on alumina beads (Al2O3). The catalyst´s doping was carried out by photo deposition with aluminum particles. The […]
A highly efficient, eco-friendly procedure has been proposed for the synthesis of 2-amino-3-phenylsulfonyl-4H-pyran derivatives via nano-cellulose-OSnCl4-x catalyst prepared from cotton as support treated with tin tetrachloride (SnCl4). This catalyst is characterized by FT-IR, FESEM, TEM, TGA, and EDX. The TEM results confirmed the size of the nano-cellulose-OSnCl4-x catalyst was below 30 nm. The efficiency of […]
