Ultrafast and high efficiency photodegradation of dyes under visible light by Au nanocluster-promoted Zn0.5Cd0.5S nanorods
Au nanoclusters decorated on the lateral surface of ultrathin ZCS nanorods could maximize the photocatalytic activity of ZCS by PRET mechanism. This makes it possible to use less photocatalysts to degrade more recalcitrant dyes in a short time.

About this collection
The combination of different components at the nanoscale continues to be a prime strategy for the development of materials with enhanced performance in a broad range of application fields. Thereby, due to the alteration of band structures, heterojunctions offer particularly fascinating possibilities for the rational design of systems with tailored properties. This Editor’s collection handpicked by Advisory Board Member Professor Georg Garnweitner (Technische Universität Braunschweig, Germany) presents most recent articles in the field of nanocrystal heterojunctions. Whilst most works focus on the synthesis of materials with superior properties for applications ranging from electro- and photocatalysis to gas sensing, electromagnetic shielding and spin valves, also mechanistic studies aiming for an enhanced understanding of heterojunction properties as well as theoretical works on the properties of heterojunction materials are included. Thus, the collection demonstrates the richness, diversity and great potentials of this research field.
