双功能Al掺杂的ZnO@SnO2异质纳米线作为光催化和表面增强拉曼散射（Sers）应用的高性能衬底进行了系统分析。在光催化方面，Al掺杂的ZnO@SnO2异质纳米线对罗丹明6 G溶液的光催化降解具有高效和可重复使用的特点，这主要归因于其对电子-空穴对复合的抑制作用和较高的表面活性位。对于Sers应用，Al掺杂的ZnO@SnO2异质纳米线显示出合适的几何形状以在三维结构中沉积具有更高密度和更多热点的存款Ag纳米颗粒，这可以提供高Sers增强、低检测限（阿莫西林10（-10）M）、高再现性和稳定性。(C)2019年韩国工业和工程化学学会。Elsevier B. V.出版，保留所有权利。
Bi-functional Al-doped ZnO@SnO2 heteronanowires systematically analyzed as high-performance substrates for photocatalytic and surface-enhanced Raman scattering (SERS) applications. For the photocatalytic application, the Al-doped ZnO@SnO2 heteronanowires can exhibit highly efficient and reusable photocatalysts in the photodecomposition of rhodamine 6G solution under low-powered UV-light irradiation, which ascribed to improve the inhabitation of electron-hole pairs recombination and higher surface active sites. For the SERS application, Al-doped ZnO@SnO2 heteronanowires revealed suitable geometry to deposit Ag nanoparticles with higher density and more hot spots in three-dimensional structures, which can provide high SERS enhancement, low detection limit (amoxicillin 10(-10)M), high reproducibility, and stability.
