A new kind of nanostructured photocatalyst, PbBiO₂Cl is synthesized by a simple hydrothermal method. The proposed formation mechanism of PbBiO₂Cl is carried out by analyzing the XRD patterns and SEM images of the products prepared under different conditions. The PbBiO₂Cl nanostructure behaves as a truncated bipyramid, exposed with {002} and {103} facets. Moreover, theoretical calculation and absorption spectrum indicate the PbBiO₂Cl shows strong absorption in the visible region with a band gap of 2.53 eV. The obtained PbBiO₂Cl nanostructures exhibit significantly enhanced photocatalytic activity on degradation of methyl orange (MO) and 4-chlorophonel (4-CP). This work may offer a paradigm on designing and synthesizing visible photocatalyst exposed with reactive facets, which can be applied in many fields.
