| Abstract: | Visible-light-responded BaZrO3 hollow nanostructure with Fe (III) doping was prepared through facile solvothermal reaction using ethanediamine (EDA) as solvent. Fe doping in BaZrO3 as an efficient way of reducing its wide band gap (～4.96 eV) is realized in order to achieve visible light response. The corresponding trapping center introduced by Fe3+ doping contributes to the lower recombination of photo-induced holes and electrons. Meanwhile, the special hollow structure with larger specific area is also a key factor to increase optical absorption, charge carrier migration rate and redox reaction sites. Hence, the participation of Fe and hollow nanostructure are responsible for the visible-light-driven photocatalytic hydrogen evolution. |
