摘　　要：以CTAB为模板在水-丁醇体系中合成了α-Fe OOH纳米棒。然后通过煅烧法制得多孔α-Fe_2O_3纳米棒。通过X-射线衍射仪(XRD)和电子扫描电镜(SEM)研究表明,α-Fe OOH纳米棒在煅烧后能获得多孔α-Fe_2O_3纳米棒,该纳米棒具有优异的可见光吸收性能,同时讨论了多孔α-Fe_2O_3纳米棒形成的可能机理。The α- Fe OOH nanorods were first prepared in water- butanol system using sodium dodecyl benzene sulfonate（CTAB）assoft- template. On onehand,theporousα- Fe_2O_3 nanorods were obtained by subsequent calcination. The samples were characterized by SEM and XRD,which indicated that the product inherited the rod- like morphology of the precursor,but its crystal had changed. We investigated the role of the surfactant in the formation of nanorod,as well as the transformation of the crystal and morphology.
