Abstract

One-dimensional SnO2-TiO2 composites were prepared via emulsion electrospinning process. The obtained samples were characterized by a series of devices. The results showed that the porous core-shell SnO2-TiO2 photocatalyst exhibited enhanced photocatalytic activity on the degradation of methyl orange (MO). It should be ascribed to the novel structure, which could separate the electrons and holes effectively.
