Abstract： |
A photocatalytic TiO2 film for cleaning water and air is prepared through dissolving the titanium alkoxiode in alcohol solvent, adding water and carbon black to obtain slurry, dipping substrate in it, and gradient calcining several times. It has high catalytic degradation rate to organic pollutant (83-93%). |
