The invention relates to a
fiber / CNT(carbon
nano tube) / TiO2 three-dimensional recyclable efficient catalytic material, as well as preparation and application thereof. A three-dimensional continuous structure is constructed on the surface of
textile fiber by CNTs, and surfaces of the CNTs are loaded with nano TiO2. Preparation comprises: soaking
fiber in a dispersion liquid containing CNT compound TiO2 and
polyethylene glycol 2000, lasting reaction for 2-4 h at 60-80 DEG C,
drying, washing with water, repeating processes of soaking,
drying and washing with water for 3-5 times, and obtaining the material. The fiber / CNT / TiO2 three-dimensional recyclable efficient catalytic material is low in cost, the preparation method is simple, requirements on equipment is are low, and the
operability is good; a
water treatment agent provided by the invention can remove high-concentration organic pollutants in water, is suitable for advanced treatment of various
wastewater, protects the environment, avoids secondary
pollution, and has the advantages of being antibacterial, removing
odor, absorbing other heavy
metal ions, and the like.
