Abstract

B-doped ZnO (B-ZnO) microspheres have been fabricated on PET-ITO flexible substrate by hydrothermal method. The B atoms play an important role in the formation of ZnO microspheres. The results of first-principles calculations demonstrate that the B atoms prefer to occupy the octahedral interstice positions as the interstitial atoms, which can lead to the decrease of band gap. The B-ZnO/PET-ITO shows significantly enhanced efficiency of photocatalytic activities with good recyclable behavior. The corresponding mechanism is discussed.
