Description
Technical field
The invention belongs to field of material preparation, be specially a kind of preparation method of natural zeolite Supported CuO nanometer tube composite materials for formaldehyde that removes.
Technical background
Formaldehyde is defined as carcinogenic and teratogenesis material by the World Health Organization, is generally acknowledged allergen, is also one of potential strong mutagen.Formaldehyde be mainly derived from artificial board, when the adhesive of the glued board in finishing material and furniture, lumber core, MDF, particieboard and heat, deliquescence, formaldehyde is just released, and industrial waste gas, vehicle exhaust, photochemical fog etc. also can discharge a certain amount of formaldehyde to a certain extent.In life, the method for the removal formaldehyde that people commonly use has ventilation method, green plants method, activated carbon method, formaldehyde scavenger method.These methods can not thoroughly be removed formaldehyde, so we are using natural zeolite synthetic zeolite Supported CuO as photochemical catalyst, utilize its adsorptivity and degradation property to reach the effect of thorough removal formaldehyde.
Photocatalysis is with TiO
2, the N-shaped semi-conducting material such as CuO is catalyst, the transform light energy of utilizing nature to exist becomes the required energy of chemical reaction, produces catalytic action, makes oxygen and hydrone around be excited into the OH that has oxidizing force
-and O
2 -free anion, almost separable solution is all to human body and harmful organic substance and the part inorganic substances of environment.Conductor photocatalysis can be used in the aspects such as sewage disposal, air cleaning, sterilization are antibacterial, automatically cleaning.
Yet Nano semiconductor photochemical catalyst particle diameter is little, easily reunite, be difficult for placing, adsorption capacity is not strong, has limited its application aspect formaldehyde treated, and therefore, scientists attempts Nano semiconductor photochemical catalyst to be fixed on some carriers, clay for example, active carbon, zeolite molecular sieve etc.Zeolite not only has uniform, nano level loose structure, this structure can form semiconductor nano cluster stable, molecular dimension, and have larger specific area, extremely strong ion-exchange capacity and absorption property, thereby zeolite-loaded type photochemical catalyst demonstrates the activity higher than other carriers.Natural zeolite is as a kind of nonmetallic mineral material, at the reserves of China, quite enriches.Lower cost, abundant reserves more and more come into one's own natural zeolite.
