摘要
The electrospinning method is employed to prepare a fibrous TiO2 - SiO2 ( Ti : Si = 1 : 2) nanocomposite photocatalyst, in which Degussa P25 TiO2 nanoparticles are embedded in the body of SiO2 fibers and which shows good photocatalytic activity due to its 3-D open structure, as evidenced by photocatalytic reduction of silver ions and decomposition of acetaldehyde.
