Hierarchical MoSe<sub>2</sub>–CoSe<sub>2</sub> nanotubes (MS–CS NTs) are <italic>in situ</italic> converted from the CoMoO<sub>4</sub> nanowires (NWs) <italic>via</italic> a facile hydrothermal selenization method.
For the first time, self-assembled coral-like hierarchical architecture constructed by NiSe2 nanocrystals has been synthesized via a facile one-pot DMF-solvothermal method. Compared with hydrothermally (H-NiSe2), DMF-solvothermally nanocrystalline (DNC-NiSe2) exhibits superior performance of hydrogen evolution reaction (HER): it very low onset overpotential ∼136 mV (vs RHE), high cathode current density 40 mA/cm2 at ∼200 and an excellent long-term stability; most importantly, delivers...
The ability to detect the full-Stokes polarization of light is vital for a variety applications that often require complex and bulky optical systems. Here, we report an on-chip polarimeter comprising four metasurface-integrated graphene-silicon photodetectors. geometric chirality anisotropy metasurfaces result in circular linear polarization-resolved photoresponses, from which parameters, including intensity, orientation, ellipticity arbitrarily polarized incident infrared (1550 nm), can be...
Self-assembled pearl-bracelet-like CoSe<sub>2</sub>–SnSe<sub>2</sub>/CNT hollow architecture was constructed using the CoSe<sub>2</sub>–SnSe<sub>2</sub> nanoboxes chained by highly conductive and flexible CNT.
For the first time, a porous and conductive Co0.85Se/graphene network (CSGN), constructed by Co0.85Se nanocrystals being tightly connected with each other homogeneously anchored on few-layered graphene nanosheets, has been synthesized facile one-pot solvothermal method. Compared to unhybridized Co0.85Se, CSGN exhibits much faster kinetics better electrocatalytic behavior for hydrogen evolution reaction (HER). The HER mechanism of is improved Volmer-Tafel combination, instead Volmer-Heyrovsky...
Abstract For the first time, a facile, ultrafast, ammonia-driven microwave-assisted synthesis of high-quality nitrogen-doped graphene quantum dots (NGQDs) at room temperature and atmospheric pressure is presented. This one-step method very cheap, environment friendly, suitable for large-scale production. The as-synthesized NGQDs consisting one to three monolayers exhibit highly crystalline quality with an average size 5.3 nm. A new fluorescence (FL) emission peak 390 nm observed, which might...
Due to the fact that crystal facets with high surface energy usually exhibit superior performance in many fields, such as catalysis, importance of synthesis micro/nano-crystals exposed is becoming a hot research field. In this article, concave Cu2O microcrystals mainly enclosed by {hhl} high-index have been successfully prepared reducing Cu(CH3COO)2 glucose presence sodium dodecyl sulphate (SDS). SDS was proved be important formation microcrystals. The degree truncated octahedra can...
In this article, single-crystalline tetrahedral Ag3PO4 microcrystals with exposed {111} facets was successfully synthesized via a facile wet chemical method. The showed the highest photocatalytic activity in visible light irradiation among {111}, {110} and {100} facets. By DFT calculations, it is demonstrated that surface energy of higher than It found largest band gap likely to suppress recombination electron–hole pairs by exploring electronic structures different surfaces Ag3PO4....
Spray drying and selenization were employed to synthesize CoSe<sub>2</sub>–MoSe<sub>2</sub>/rGO-C (CS-MS/rGO-C), which delivers superior HER performance in acidic alkaline media.
For the first time, large-area, vertically oriented few-layered hafnium disulfide (V-) nanosheets have been grown by chemical vapor deposition. The individual are well [001] oriented, with highly crystalline quality. Far different from conventional van der Waals epitaxial growth mechanism for two-dimensional transition metal dichalcogenides, a novel dangling-bond-assisted self-seeding is proposed to describe of V- nanosheets: difficult migration adatoms on substrate surface results in seeds...
CeO2 nanocubes and truncated octahedra have been synthesized with different capping agents in the alkaline environment. The present enhanced catalytic properties CO oxidation, which may be due to existence of more coordination unsaturated cerium atoms active adsorption dissociated oxygen species on (100) surface.
Clean hydrogen split from water by evolution reaction (HER) is significant for sustainability, environmental emissions, and energy security. So far, it still a big challenge to develop highly efficient noble metal-free electrocatalysts with comparable HER efficiency platinum-based catalysts, which are mainly hindered the intrinsic electrocatalytic property particularly reasonable nanostructure design of electrocatalyst. Here we report newly-designed three-dimensional hierarchical MoSe2...
