The development of heterojunction photocatalysts is still limited by poor interfacial charge carriers separation efficiency. In this work, we have successfully designed CdS/Pt/N-NaNbO₃ multilayer bridged nanostructure by embedding of Pt nanoparticles (NPs) into the interface between CdS quantum dots (CdS QDs) and perovskite N-doped NaNbO₃. The Pt NPs not only play the role of bonding CdS QDs and NaNbO₃, but also provide a motive force for the charge carriers transfer and enormously shorten the migration path. Apart from the efficient Z-scheme charge transmission path of the CdS/Pt/N-NaNbO₃ nanorods, strong visible light absorption (400−800 nm) can also be tailored by N doping and introducing of Pt NPs, CdS QDs, demonstrated by the UV–vis. DRS measurement. As expected, the photocatalytic hydrogen evolution rate of 18 %CdS/2%Pt/N-NaNbO₃ nanorods is 134 and 28 times higher than that of bare NaNbO₃ nanorods and CdS QDs, respectively, under visible light (λ > 420 nm). This is the highest value so far reported among the NaNbO₃-based photocatalysts. This study has important implications for photocatalytic hydrogen evolution and novel fabrication of NaNbO₃-based materials.

界面电荷载流子分离效率差仍然限制了异质结光催化剂的发展。在这项工作中，我们通过将Pt纳米颗粒（NPs）嵌入CdS量子点（CdS QDs）和钙钛矿N掺杂NaNbO ₃之间的界面中，成功设计了CdS / Pt / N-NaNbO ₃多层桥接纳米结构。Pt NPs不仅起CdS QDs与NaNbO ₃的键合作用，而且为电荷载流子的迁移提供动力，极大地缩短了迁移路径。除了CdS / Pt / N-NaNbO ₃的高效Z方案电荷传输路径纳米棒具有很强的可见光吸收（​​400-800 nm），也可以通过N掺杂和引入Pt NP，CdS QD来定制，这在UV-vis上得到了证明。DRS测量。不出所料，在可见光（λ> 420 nm）下，18％CdS / 2％Pt / N-NaNbO ₃纳米棒的光催化氢释放速率分别比裸NaNbO ₃纳米棒和CdS QD高134和28倍。。这是迄今为止基于NaNbO ₃的光催化剂中最高的值。这项研究对光催化氢的释放和基于NaNbO ₃的材料的新颖制造具有重要意义。
