Abstract:
Low-dimensional Bi2Fe4O9 nanosheets and microrods have been selectively prepared by a solvothermal method, from which the growth of the Bi2Fe4O9 crystals can be controlled by the variation of reaction conditions. Structure determination showed that the nanosheets are mainly exposed by {001} facets while the microrods are exposed by {110} facets. Photocatalytic investigation demonstrated that the overall photocatalytic activity of the microrods is prior to the one of the nanosheets although the microrods have a relative large size. The result suggested that the {110} facets would be more active than those of {001} facets. The present report provides a useful alternative strategy for the controlling growth of nanostructures and/or microcrystals besides the present demonstration of the Bi2Fe4O9 crystals with different facets that would be able to tune the corresponding photocatalytic ability selectively.
