1.Titanium dioxide photo-catalytic xz - g02 is of good light catalytic performance. This photo-catalytic can use light wavelengths of light energy to produce light  photocatalytic effect.
2.To make the oxygen and water molecules which adhere to the material surface stimulate generate OH-and O2 free ions with super activity .These strong oxidizing free radicals can decompose  almost organic matter and part of inorganic substances  which is harm to human or environment , and finally can decompose organic, bacterium to carbon dioxide and water. Therefore nano-tio2 light catalysis xz - g02 can have the function of deodorization, antibacterial disinfection, purify air and clean.  
3.Decomposition carbon dioxide can attract mosquitoes,  plus the mosquitoes attacted Violet tube in it,through cover a very silent, mute motor wind attraction. will attract mosquitoes to the blow voltage electrode below, will kill mosquitoes and play the role of deinsectization.
