Abstract The effort to enhance the visible-light photoresponse of SnO2 and SnO has been designed by the heterostructure formation of tin oxide. The formation was conducted by controlling the oxidation state of precursor through adjusting the precursor acidity. The result shows that the transformation route as a function of precursor initial pH involve the formation of intermediate phase began by SnO2 to SnO2/Sn3O4 to SnO/Sn3O4, and finally SnO. The characterization indicated that Sn3O4 played the important role in enhancing the visible light response of both SnO2 and SnO in the heterostructure formation.

使用一步水热法通过异质结构形成增强 SnO 和 SnO2 的可见光光响应

摘要 通过氧化锡的异质结构形成，设计了增强 SnO2 和 SnO 的可见光光响应的努力。通过调节前驱体酸度来控制前驱体的氧化态进行形成。结果表明，作为前体初始 pH 值函数的转变路线涉及中间相的形成，从 SnO2 开始到 SnO2/Sn3O4 再到 SnO/Sn3O4，最后是 SnO。表征表明，SnO4 在增强异质结构形成中 SnO2 和 SnO 的可见光响应方面发挥了重要作用。
