TiO2 nanofibers(TNFs)with carbon layers(~15nm thickness)and wolfram(0.5%,1%,1.5%)(0.5%WTC,1%WTC,1.5%WTC)were fabricated by combining the electrospinning technique and hydrothermal method,and the consequent assembly of WTC core/shell hybrid nanofibers on a ultra-long electrospun one-dimensional W-TiO2 template.As compared with the pure TNFs and TNFs@carbon(TC),WTC exhibited an enhanced photocatalytic efficiency for the solar H2 generation performance.Investigations demonstrated that the enhancement can be attributed to the nanofibers network structure[1] and high separation efficiency of photogenerated electrons and holes based on the synergistic effect between carbon as a sensitizer and TiO2.[2] Moreover,the exists of wolfram results in added donor levels that tend to be localized midgap states to preserve charge neutrality.[3] Notably,the WTC fibers could be easily recycled due to their one-dimensional nanostructural property.Fig.
