Purpose The purpose of this paper is to provide an investigation on a new kind of photocatalytic material, namely, the porous ceramic foam loading titanium dioxide, which can make an effective photocatalytic degradation of the methyl orange (MO) solution in the wastewater. Design/methodology/approach The natural zeolite powder has been used as the primary raw material to produce a sort of lightweight porous ceramic foam by impregnating polymer foam in slurry and then sintering. With the sol-gel method, a kind of open-cell reticular porous ceramic foam loading TiO2 film was obtained having a good photocatalytic action, and the resultant porous composite product presents the bulk density of 0.3~0.6 g/cm3 to be able to float on water. Findings The MO could tend to be completely degraded in the solution with a certain concentration by the TiO2-loaded ceramic foam irradiated with ultraviolet light, and this composite foam was found to have high degradation efficiency for the MO solution in a wide range of pH. Originality/value This work presents a TiO2-loaded ceramic foam that can effectively photo-catalyze to degrade the MO in water, and the degradation efficiency were examined under different conditions of the MO solution with various pH values.

Lanthanum doping TiO2 were prepared by sol-gel method, an the photocatalytic degradation experiments were performed by using methyl orange solution as a target degradant. The results indicated that Suitable doping quantity of lanthanum can improve the photocatalytic activity of nanometer TiO2 powders. On the basis of 50 mL methyl orange solution what concentration is 20 mg/L, photocatalytic activity is the best when doping quantity of lanthanum were 1.0 wt %. Through the relatively experiments by using sunshine and ultraviolet as light source, the results indicated that the La3+ doping broaden the scope of visible light area what TiO2 response to.
