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...
