Electrospun nanofibers of TiO2/CdS heteroarchitectures with enhanced photocatalytic activity by visible light

► The size and content of CdS nanoparticles grown on TiO2 nanofibers are tunable. ► TiO2/CdS nanofibers have higher photocatalytic activity by visible light. ► The electrospinning method combined with hydrothermal process is novel and valuable.
