Abstract The design and development of particulate photocatalysts have been an attractive strategy to incorporate earth‐abundant metal ions to water splitting devices. Herein, we synthesized CoFe‐Prussian blue (PB) coated ZnO origami core‐shell nanostructures (PB@ZnO) with different massratios of PB components and investigated their photocatalytic water oxidation activities in the presence of an electron scavenger. Photocatalytic experiments reveal that the integration of PB on ZnO boosts the oxygen evolution rate…

Abstract Heterostructures of Cobalt‐Iron (Co‐Fe) Prussian blue analogues (PBA) and inorganic semiconductors are attractive materials for photocatalytic and photoelectrochemical water oxidation. Their efficiency is rooted in the charge transfer (CT) at the PBA|semiconductor interface. The interfacial CT, however, often suffers from sluggish kinetics, optimization of which has been elusive. In this work, we investigate PBA|ZnO heterostructures spectroscopically and show that tuning the interfacial composition of the…

Solution-processable materials attract significant interest in the development of high-efficiency, cost-effective optoelectronic devices. However, widely used high-performance materials often suffer from high toxicity, low biocompatibility, and synthesis procedures hazardous to human health and the environment. As cost-effective, sustainable alternatives to the conventional solution-processed semiconductors, here we evaluate the potential of plant extracts. Within this framework, here we present photodetectors emp…

We investigated the effect of light on the DNA-driven self-assembly to form hierarchical patterns on two dimensional surfaces. We specifically focused on the self-assembly of DNA-functionalized quantum dots (QDs) onto DNA-functionalized glass substrate while illuminating the surface with a laser during coating process. The region illuminated with a green laser remained uncoated with red-emitting QDs while the not-illuminated region was successfully coated. Next, a red laser whose light cannot be absorbed by the re…

The development of novel strategies for self-assembly in the field of nanotechnology has witnessed remarkable progress in recent years. Here, we present a DNA-driven programmable self-assembly to fabricate the targeted nanophotonic structures. The exploitation of the programmable properties of DNA and the unique optical properties of QDs unfolds the ability to engineer complex nanostructures with laser irradiation. The main advantages of this method are the precise interaction of colloidal quantum dots (QDs)/nanop…
