TiO2@V2O5 core-shell hollow porous microspheres (HPMs) are successfully synthesized.
Photodegradation rate of TiO2@V2O5 core-shell HPMs towards benzene is greatly enhanced.
Light absorption range of TiO2@V2O5 core-shell HPMs is extended due to the narrowed band gap.
The photogenerated electrons and holes are effectively separated for TiO2@V2O5 core-shell HPMs.
