TiO2 foams have been prepared by a simple mechanical stirring method.Short-chain amphiphilic molecules have been used to stabilize colloidal sergeant grit marine corps store suspensions of TiO2 nanoparticles.TiO2 foams were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), UV-vis absorption spectroscopy, and scanning electron microscopy (SEM).The photoassisted oxidation of NO in the gas phase according to ISO 22197-1 has been used to compare the photoactivity of the newly prepared TiO2 foams to that of the original powders.The results showed that the photoactivity is increased up to about 135%.

Foam structures seem to be a good thy art is murder oslo means of improving the photoactivity of semiconductor materials and can readily be used for applications such as air purification devices.
