Abstract

Self-assembled CeO₂ hierarchical rose flower-like nanostructures (HRFNs) and Fe-doped CeO₂ hierarchically porous nanostructured (HPNs) thin films were synthesized by solvothermal method followed by thermal annealing process. Optical absorption for Fe-doped CeO₂ HPNs showed an enhanced photoabsorption ability with an estimated band gap energy value of 2.63 eV. Photocatalytic degradation results showed that Fe-doped CeO₂ HPNs exhibited an excellent photocatalytic activity in degrading Methylene Blue (MB) dye under UV-visible light irradiation compared with those of CeO₂ HRFNs. The degradation rate of Fe-doped CeO₂ HPNs was found to be 80% after 180 min and obeys pseudo-first-order equation.
