Combining the versatility of electrospinning technique and hydrothermal growth of nanostructures enabled the fabrication of hierarchical CeO{sub 2}/TiO{sub 2} nanofibrous mat. The as-prepared hierarchical heterostructure consisted of CeO{sub 2} nanostructures growing on the primary TiO{sub 2} nanofibers. Interestingly, not only were secondary CeO{sub 2} nanostructures successfully grown on TiO{sub 2} nanofibers substrates, but also the CeO{sub 2} nanostructures were uniformly distributed without aggregation on TiO{sub 2} nanofibers. By selecting different alkaline source, CeO{sub 2}/TiO{sub 2} heterostructures with CeO{sub 2} nanowalls or nanoparticles were facilely fabricated. The photocatalytic studies suggested that the CeO{sub 2}/TiO{sub 2} heterostructures showed enhanced photocatalytic efficiency of photodegradation of dye pollutants compared with bare TiO{sub 2} nanofibers under UV light irradiation.
