Porous nano-TiO2 prepared by the sol-gel technology was coupled with Fe3O4 which is magnetic material prepared by marinating-calcining method to afford the magnetic porous coupling Fe3O4/TiO2 photocatalyst, the title compound was characterized. In this paper, we investigated the degradation to the bromamine acid solution under the fluorescent light and the effects of different adulterant proportion...
SnO2/Al2O3 nanofibers have been fabricated from a suitable inorganic-organic composite solution via a simple electrospinning method and followed by calcination treatment of the electrospun polymer/inorganic composite fibers. The effect of voltage, tip-to-collector distance and calcining temperature on the morphology and crystal structure of nanofibres was investigated by scanning electron microscope...
Titanium dioxide nanotubes were prepared and used as catalyzers for titanium dioxide nanotubes/UV/O3 to degrade humic acid. And the optimal parameters of titanium dioxide nanotubes/UV/O3 were investigated. The combined treatment showed the synergetic effect of photocatalysis and ozonation. When calcined at 400degC, titanium dioxide nanotubes had the best catalysis for photocatalytic ozonation. With...
This paper investigated the catalytic ozonation of aqueous nitrobenzene (NB) in the presence of nano-TiO2/zeolite. The removal efficiency of NB was increased from ozone alone at 12.57% to in the present of catalyst at 33.76%, significantly. The optimum calcination temperature of nano-TiO2/zeolite was found out at 600degC. Catalytic ozonation of nitrobenzene was first order reaction with respect to...
Manganese-based catalysts supported on TiO2 were studied for the oxidation of NO to NO2 in excess oxygen to remove NO from flue gas. Catalysts were prepared by incipient impregnation, excessive dipping and ultrasonic improved impregnation. The effects of precursor, manganese loadings, preparation method of catalysts and calcination temperature of catalysts on NO oxidation were investigated in details...
