异质结构构建被认为是实现纳米材料性能最优化的一条可行途径。尽管在异质结制备方面进行了令人印象深刻的研究,但组装不同的多晶型形成异质结的研究很少集中在相关方面。在这项工作中,我们展示了Cu2S/CuS多晶型通过阳离子触发自组装在SnS2衬底上实现了可调谐的局域表面等离子体共振(LSPR)。在转变过程中,Covellite相的形成是通过阳离子交换进行的,而辉铜矿相的形成是通过改变阴离子骨架的氧化还原状态来实现的。此外,在SnS2衬底上形成的具有优化比例的多晶型通过不同多晶型的本征能带排列增强了载流子参与的过程,与衬底上以单相为主的硫化铜相比,具有优异的光催化性能。因此,我们希望这种具有独特性质的可控纳米结构的制备能够为光电化学的应用提供一些有用的提示。
Heterostructure construction has been regarded as a feasible pathway for nanomaterial fabrication towards optimized properties. Despite impressive investigations on heterostructure fabrication, assembling distinct polymorphs to form heterojunction has seldom been focused on relevant aspects. In this work, we demonstrated tunable localized surface plasmon resonance (LSPR) by Cu2S/CuS polymorphs via cation-triggered self-assembling on SnS2substrates. During the transformation, the forming of covellite phase proceeds through cation exchange, while the simultaneous formation of chalcocite phase was achieved by the variation of the redox states of the anion framework. Furthermore, the formed polymorphs with optimized proportion on SnS2substrates exhibited enhanced charge-carrier-involved processes by intrinsic band alignment in distinct polymorphs, resulting in excellent photocatalytic performances compared with those single-phase dominant copper sulfides on substrates. We thus hope this controllable nanostructure fabrication with distinctive properties could provide some useful hints for photo-electrochemistry applications.
