title: Construction of teethlike homojunction BiOCl (001) nanosheets by selective etching and its high photocatalytic activity.
abstract: Teethlike homojunctions BiOCl (001) nanosheets with tunable photoresponse were constructed by selective etching with triethanolamine and allowed fast charge separation across the interfaces to facilitate photocatalysis. The unique microstructure exhibits a superior photocatalytic activity that can be ascribed to the combined interaction of the high UV/vis light harvest, high photogenerated charge separation efficiency, and the fast interfacial charge-transfer rate based on the unique homogeneous topotactic structure. We believe that the creation of this new model junction may be a great aid in the design and preparation of efficient semiconductor based photocatalysts and a new understanding of the essential relation between the junction and the photocatalytic activity.
