In article number 2005254, Xiaoyan Zhang and co-workers summarize the recent progress in construction of heterostructures based on black phosphorus nanosheets, ranging from 2D hybrid structures to 3D networks. The preparation methods, optical electronic properties, various applications these are discussed. Critical challenges future directions this area also highlighted.

The topological insulator 2D Bi2Se3 is promising for electronic devices due to its unique properties; however, it challenging prepare antioxidative nanosheets since prone oxidation. Surface passivation using ligand agents after exfoliation works well protect the surface, but process time-consuming and technically challenging; a agent that stable under highly biased potential significant in situ...

SnO2 nanosheet-structured films were prepared on a fluorine-doped tin oxide (FTO) substrate using ZnO nanosheet as template. The as-prepared SnO2 nanosheets contained plenty of nano-voids and were generally vertical to the substrate. TiO2 nanoparticles were homogeneously deposited into the intervals between the SnO2 nanosheets to prepare a hierarchically structured SnO2/TiO2 hybrid film. The hy...

High Curie temperature ferromagnetism has been realized in atomically thin MoS2 and WS2 nanosheets. The ultrathin nanosheet samples were prepared via a novel, simple and efficient chemical vapor deposition method; different kinds of transition metal disulfides (MoS2 and WS2) could be obtained by sulphuring the corresponding cation sources (MoO3 and WCl6). Through related morphological and struc...

In this paper, ZnO nanorod-nanosheet hierarchical structures were fabricated using a facile method on zinc foil and used as flexible photoanodes in dye-sensitized solar cells (DSCs). Compared to nanorods (NRs) obtained by the dissolution-precipitation method, the nanorod-nanosheet (NR-NS) hierarchical structures obtained by a second-step homogeneous precipitation improved the performance of DSC...

Transition metal oxides and graphene composites have been widely reported in energy storage and conversion systems. However, the controllable synthesis of graphene-based nanocomposites with tunable morphologies is far less reported. In this work, we report the fabrication of V2O5 and reduced graphene oxide composites with nanosheet or nanoparticle-assembled subunits by adjusting the solvotherma...

MicroRNAs (miRNAs) play vital roles in physiologic and pathologic processes and are significant biomarkers for disease diagnostics and therapeutics. However, rapid, low-cost, sensitive, and selective detection of miRNAs remains a challenge because of their short length, sequence homology, and low abundance. Herein, we report for the first time that WS2 nanosheet can exhibit differential affinit...

Activation of the CH bond is first step in converting methane into valuable chemicals. Herein, successful induction and electrical detection a oxidation reaction are reported at room temperature using IrO2 nanosheets, 2D form IrO2. A clear decrease resistance upon exposure to observed by atomically thin nanosheet films. The disappears simultaneous oxygen, suggesting that oxidized consuming lat...
