Photocatalytic activity of TiO2 supported SiO2-Al2O3 aerogels prepared from industrial fly ash

A ternary composite of TiO2 and a SiO2-Al2O3 aerogel with good photocatalytic activity was prepared by a simple sol-gel method with TiO2 nanoparticles and SiO2-Al2O3 aerogels derived from industrial fly ash. The structural features of the TiO2/SiO2-Al2O3 aerogel composite were investigated by X-ray powder diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy, gas adsorption measurements and diffuse reflectance UV-visible spectroscopy. The optimal conditions for photocatalytic degradation of 2-sec-butyl-4,6-dinitrophenol (DNBP), included an initial DNBP concentration of 0.167 mmol/L at pH = 4.86 with a catalyst concentration of 6 g/L, under visible light irradiation for 5 h. A plausible mechanism is proposed for the photocatalytic degradation of DNBP. Our composite showed higher photocatalytic activity for DNBP degradation than that of pure TiO2. This indicates that this material can serve as an efficient photocatalyst for degradation of hazardous organic pollutants in wastewater.

Cold microwave chemistry: synthesis using pre-cooled reagents

A novel experimental procedure for chemical reactions has been devised that involves mixing and then freezing the reagents (organic solvent-free) to a sub-zero temperature such as -30 °C. This frozen mixture is exposed to microwave irradiation for a brief period of time. The use of pre-cooled reagents may give a single product not obtained by traditional microwave irradiation at room temperature. Interestingly, such a product may provide information about mechanisms by identifying the first step of a multiple step reaction.

Ethylene polymerization by self-immobilized neutral nickel catalysts bearing allyl groups

[Ni(Ph)(PPh3)(N,O)] complexes containing phenyliminophenolato ligands (N,O) (1: N,O = A; 2: N,O = B; 3: N,O = C; 4: N,O = D; 5: N,O = E) have been synthesized and characterized. The molecular structure of 4 was determined by singlecrystal X-ray analysis. Complexes 2-5 bearing allyl groups have been investigated as self-immobilized catalysts for ethylene polymerization without the use of co-catalysts. The high ethylene polymerization activities of ca. 105 g·PE mol-1 Ni·h-1 and high molecular weight (MW ≈ 105) of polyethylene could be accomplished by changing the ligand structures and reaction conditions. The self-immobilization of catalysts brings about a dramatic increase in the catalytic activities of ethylene polymerization. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003.
