BiOBr with different preferred growth orientation facets would show a photocatalytic performance. When decorated in situ metallic Bi nanoparticles, Bi/BiOBr commonly display an enhanced In this paper, the nanoplates (102) facet and (110) were first synthesized using hydrothermal method. Then, some nanoparticles modified onto (110)BiOBr nanoplates, which was expected to much more All samples characterized XRD, FE-SEM, TEM, N2 adsorption–desorption, UV–vis XPS.
