Description
Summary:This work demonstrates the fabrication of nanoporous BiVO 4 /ZnO nanosheets heterostructures grown on stainless steel mesh. The ZnO nanospheres were used as precursors for ZnO nanosheets, and the number of ZnO nanosheets increased with an increase in the diameter of ZnO nanospheres. Photodegradation experiments confirmed that BiVO 4 /ZnO nanocomposites derived from ZnO nanospheres with a diameter of 300 nm (BVO/ZnO-300) exhibited higher photocatalytic performance than other BiVO 4 /ZnO hybrids. In addition, the construction of the architectures on stainless steel mesh is beneficial for practical application since the photocatalysts could be easily recycled and reused without any special recycling procedures.
