| Abstract |
The 3D hierarchical ZnO/Bi2MoO6 heterojunctions were fabricated via an in-situ solvothermal method. To
the best of our knowledge, this is the first report based on synthesis of ZnO/Bi2MoO6 heterojunction by
decoration of ZnO nanoparticles on the surface of the flower-like Bi2MoO6 superstructures. The prepared
ZnO/Bi2MoO6 heterojunctions exhibited the characteristic diffraction peaks of ZnO and Bi2MoO6 with the
band gap energy of 3.25 eV and 2.76 eV, respectively. The PL intensity of the 10 wt% ZnO/ Bi2MoO6
heterojunction (denoted as 0.10Zn–Bi) is much lower than that of the bare Bi2MoO6, indicating much
more effective separation of photo-generated electrons and holes at the interface which in turn results
in greater expected photocatalytic performance. The 0.10Zn–Bi heterojunction showed the highest efficiency
of 100% and 92% toward photodegradation of OFL antibiotic and RhB dye, respectively, due to
the greatest surface area and the lowest electron-hole recombination rate. The photodegradation of
the pollutants followed pseudo-first order kinetics with a very high rate constant of 0.0196 min1. The
chemical structure of photocatalyst remained stable after five cycles of use. The photogenerated electron
(e) and hole (h+) are two major reactive species involved in photodegradation of both OFL antibiotic and
RhB dye. The present work demonstrates a very high potential of the 3D hierarchical ZnO/Bi2MoO6
heterojunctions for environmental remediation. |
