Development of new multifunctional nanostructures relies on the ability to make new materials at the nanoscale with control over size, shape and composition. While this control is extremely important to tune several properties, an alternative strategy is to create active interfaces between two or more nanostructures to form nanoscale heterostructures. In these heterostructures, the interfaces play a key role in stabilizing and enhancing the efficiency of the individual components for various applications. In this article, we discuss synthesis methods of different types of nanoscale heterostructures and the role of interfaces in various applications. We present the current state-of-the-art in designing heterostructures and possible upcoming synthetic strategies with their advantages and disadvantages. We present how such heterostructures are highly efficient for catalytic, photovoltaic and nanoelectronic applications drawing several examples from our own studies and from the literature.
新型多功能纳米结构的发展依赖于在纳米尺度上制造新材料的能力,这种能力可以控制材料的尺寸、形状和组成。虽然这种控制对于调整多种性能非常重要,但另一种策略是在两个或更多纳米结构之间创建活性界面,以形成纳米级异质结构。在这些异质结构中,界面在稳定和增强各个组件的效率方面起着关键作用,适用于各种应用。在本文中,我们讨论了不同类型的纳米级异质结构的合成方法以及界面在各种应用中的作用。我们介绍了异质结构设计的最新进展以及可能的未来合成策略,包括它们的优缺点。我们介绍了这种异质结构如何在催化、光伏和纳米电子应用中非常有效,通过我们自己的研究和文献中的几个例子来说明这一点。
