A Composite Of Single-Crystalline Bi2wo6 And Polycrystalline Biocl With A High Percentage Of Exposed (00l) Facets For Highly Efficient Photocatalytic Degradation Of Organic Pollutants

A composite of single-crystalline Bi2WO6 and polycrystalline BiOCl with a high percentage of exposed (00l) facets was fabricated by the molten salt method (MSM) in the presence of polytetrafluoroethylene (PTFE). The photocatalytic activity of the composite was 17 and 70 times that of Bi2WO6 prepared by the MSM without PTFE and the traditional solid state reaction method, respectively.
