Preparation method of PE fiber loaded TiO2 photocatalyst

The invention discloses a preparation method of a PE (Poly Ethylene) fiber loaded TiO2 photocatalyst, which comprises the following steps of: preparing TiO2 sol by adopting a sol-gel method, and directly loading the TiO2 sol by adopting PE fibers in a dipping form to obtain the PE fiber loaded TiO2 photocatalyst. According to the preparation method of the PE fiber loaded TiO2 photocatalyst, the obtained TiO2 particles are uniformly distributed in the carrier material PE fiber and are not easy to fall off during water treatment, so that the improvement of the photocatalytic efficiency and the recycling are facilitated. 本发明公开一种PE纤维负载TiO2光催化剂的制备方法，先采用溶胶凝胶法制备TiO2溶胶，然后采用PE纤维直接以浸渍形式负载TiO2溶胶的方法，得到该PE纤维负载TiO2光催化剂。本发明一种PE纤维负载TiO2光催化剂的制备方法，得到的TiO2颗粒在载体材料PE纤维中分布均匀且水处理时不易脱落，有助于光催化效率的提高及循环使用。
