A novel one-step cation exchange approach has been developed to prepare ZnO-decorated ZnSe nanorods (ZnSe-ZnO NRs), a prototype type-II semiconductor nanoheterostructure. Because of the staggered band offset which promoted effective charge separation, the as-synthesized ZnSe-ZnO NRs exhibited remarkable photocatalytic activities under visible light illumination, demonstrating their promising potentials in relevant photoconversion applications.
一种新型的一步阳离子交换法被开发用于制备 ZnO 修饰的 ZnSe 纳米棒（ZnSe-ZnO NRs），这是一种原型的 II 型半导体纳米异质结构。由于带阶错导致的有效电荷分离，所合成的 ZnSe-ZnO NRs 在可见光照射下表现出显著的光催化活性，这表明它们在相关的光转换应用中有很大的应用潜力。
