Oxygen vacancy defects (OVs) are one of the main strategies for nanomaterials modification to improve the photoactivity, but current methods for fabricating OVs are usually complicated and harsh. It is important to develop simple, rapid, safe, and mild methods to fabricate OVs. By studying the effects of different weak reducing agents, the concentration of the reducing agent and the reaction time...
It has been reported that N and B doping induce a quasi-bound state that suppresses the conduction in graphene nanoribbon (GNR)-based junctions, while an H defect or a pyridine-like N-atom (PN) substitution at the edge of the GNR does not affect the transmission close to the Fermi energy. However, these results may vary when the size of the functional unit of the GNR junction decreases to a molecular...
Hierarchical SnO2 nanoflowers, assembled from single‐crystalline SnO2 nanosheets with high‐index (11$ \bar 3 $) and (10$ \bar 2 $) facets exposed, are prepared via a hydrothermal method using sodium fluoride as the morphology controlling agent. Formation of the 3D hierarchical architecture comprising of SnO2 nanosheets takes place via Ostwald ripening mechanism, with the growth orientation regulated...
