Controlled synthesis of one-dimensional BiOBr with exposed (110) facet and enhanced photocatalytic activities

Abstract

Novel one-dimensional rod-like BiOBr with exposed (110) facets (BiOBr-110) are synthesized by self-sacrifice template method using glucose as capping agent and structure-directing agent. The glucose can interact with (001) facet of the BiOBr nanoparticles and suppress the growth of these planes, which results in the formation of ultrathin BiOBr nanosheets exposed (001) facet. At the same time, glucose induces these ultrathin nanosheets to assemble along [001] orientation of BiOBr nanosheet, resulting in the formation of BiOBr nanorod exposed (110) facet. BiOBr-110 displays better photocatalytic capability than BOBr-001 for dyes degradation, which is attributed to a higher conductive band potential and narrower band gap in BiOBr-110. Additionally, the BiOBr-110 has higher charge transfer efficiency and lower charge transfer resistance than BiOBr-001. This work would offer a simple method to control the synthesis of BiOBr with exposed (110) facet.
