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...
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...
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...
Black phosphorus nanoparticles (BP NPs) possess great advantages in photocatalysis owing to the rich surface active sites, extremely high carrier mobility, and strong visible–near-infrared light response. However, complex preparation process, poor stability, rapid recombination restrict their successful application photocatalysis. Herein, above problems are resolved by preparing BP NPs through a facile sonication-assisted hydrothermal method. To further improve stability photocatalytic...
Abstract In this study, a new type of lead‐free double perovskite Cs 2 TeBr 6 combined with metal‐free semiconductor g‐C 3 N 4 heterojunction is constructed and used for photocatalytic CO reduction the first time. The S‐scheme charge transfer mechanism between systematically verified by X‐ray photoelectron spectroscopy (XPS), electron spin resonance (ESR) in situ Fourier infrared spectroscopy(FT‐IR). formation S‐type makes photocatalyst have higher separation ability highest redox ability....
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...
In this study, the separator coated with reduced graphene oxide (rGO) layer is prepared via doctor blading. The lithium-sulfur (Li-S) battery rGO-coated exhibits much smaller impedance and better electrochemical performance. After rGO, initial discharge capacity can be as large 1067 mAh g−1 at 0.2 C which retain 878 after 100 cycles, reach 710 even 2 C. significant performance enhancement attributed to bi-functionality of rGO; rGO coating has unique porous structure, high conductivity...
High-quality, reduced graphene oxide (RGO) homogeneously coated LiCo1/3Ni1/3Mn1/3O2 (NCM) was synthesized by ultrasonically mixing/stirring GO and NCM in water then thermal reduction of to RGO. The composite cathode shows much higher specific capacity, better cycling stability high rate performance after being wrapped RGO, which is attributed the lower electrochemical impedance for electrode due presence It promising RGO modified be used as an excellent cathode.
