Abstract Transition metal oxides (TMOs) with high theoretical capacities are promising anode candidates for sodium ion batteries (SIBs), which yet suffers from inferior cycling stability and rate capability due to large volume change and sluggish transport kinetics during the sodiation/desodiation processes. Herein, a general strategy is developed to fabricate ultrafine TMOs nanoparticles encapsulated in nitrogen-doped carbon nanofibers (uf-TMOs@N-CNFs, M=Fe, Mn, Zn, etc.) as advanced anodes for...

Abstract Acetylcholinesterase (AChE) plays an essential role in biological signal transmission, the aberrant expression of which could cause diverse neurodegenerative diseases. Herein, based on the oxidase-like activity of manganese dioxide nanosheets (MnO2 NSs), we found that MnO2 NSs could directly oxidize thiamine into intensely fluorescent thiochrome without the need of peroxides. When AChE was introduced, acetylthiocholine could be hydrolyzed to generate thiocholine, which efficiently trigg...

MoS2-based hybrids have aroused great interest for their outstanding performance in the application of biochemical sensing, catalysis and energy storage filed. Herein, we present a facile strategy to fabricate hierarchical microtubes by cultivating a MoS2 sheet-like nanostructure on polypyrrole microtubes (designated as PPy@MoS2 microtubes) using MoO3@PPy micro-cables as self-sacrificial templates. Such dissolution-regrowth mechanism is demonstrated for the formation of hierarchical PPy@MoS2 mic...

Abstract The rapid hydrolysis of acetylcholine (ACh), one of the key neurotransmitters in the human body, by the enzyme acetylcholinesterase (AChE) is fundamental for the termination of ACh impulse transmission. Several chemicals, including organophosphorus (OP) pesticides, warfare agents and drugs, are AChE reversible or irreversible inhibitors, thus their rapid on-site detection is of primary importance. Here we report for the first time a chemiluminescence (CL) foldable paper-based biosensor ...

Abstract Herein, we report a facile and straight strategy to synthesize a highly efficient and recyclable heterogeneous catalyst through a pyrolysis−oxidation of core−shell Zn/Co metal organic frameworks (MOFs). The selected Zn MOF crystals was used as a single precursor to form a nanostructured hollow framework through the evaporation of Zn at high pyrolysis temperature. Meanwhile, the numerous carbon nanotubes (CNTs) was formed on the surface of a hollow nanostructured framework under the cata...

Abstract The exploitation of multifunctional nanocomposites is highly desired in environmental monitoring, biosensors, and medical diagnosis. In this paper, a simple approach has been proposed to fabricate MoS2 decorated N-doped carbon nanotubes (NCNTs@MoS2) hybrid composites as efficient peroxidase-like mimics. The combination of the MoS2 and N-doped carbon nanotubes (NCNTs) brings about an enhanced synergistic effect, leading to remarkably decent intrinsic peroxidase-mimic activities than that...

The Co/N doped carbon material, as an important electrocatalytic material, has been attracted intense interest in ORR and Zn-air battery. Here, we report an efficient Co@N-doped carbon catalyst (Co@N-C-1) obtained by pyrolysis of ZIF precursor with 2-aminobenzimidazole. The introduction of 2-aminobenzimidazole results in the formation of hierarchical meso/microporous structure of the as-prepared Co@N-C-1, effectively avoiding the aggregation of Co nanopariticles during pyrolysis and the higher N...

Abstract Nanozymes become currently a frontier of chemical research. However, exploiting a novel nanozyme with high activity, good stability and reproducibility is challenging. Here, size-controllable Fe-N/C nanozymes containing exclusive single Fe atoms coordinated Fe-Nx sites were succesfully prepared through a facile pyrolysis of size controllable Fe-Zn ZIFs precursors. The Fe-N/C nanozymes exhibit exceptional high oxidase-mimicking activity able to catalyze oxidation of colorless 3,3',5,5'-t...
