A novel gelatin-guided mesoporous bowknot-like Co3O4 anode material for high-performance lithium-ion batteries

Abstract: A mesoporous bowknot-like Co3O4 material has been synthesized through a facile hydrothermal method, using cobalt nitrate as the cobalt source, urea as the precipitator and gelatin as the guide agent, followed by calcination at 600 °C in air. Morphology characterization reveals that this bowknot-like Co3O4 material possesses a mesoporous structure consisting of nanoparticles. Electrochemical experiments illustrate that the mesoporous bowknot-like Co3O4 anode material exhibits a superior first and 100th reversible specific capacity of 1427.9 mA h g−1 and 1388.8 mA h g−1 at 0.2C, respectively. This material also delivers a high charge capacity of 751.3 mA h g−1 after 150 cycles at 2C. The novel preparation method and satisfactory performance make the bowknot-like Co3O4 a good candidate as a high-performance anode material for use in Lithium-Ion Batteries (LIBs).

Enzymatic reaction modulated gold nanorod end-to-end self-assembly for ultrahigh sensitively colorimetric sensing of cholinesterase and organophosphate pesticides in human blood.

Abstract: We present herein the first reported self-assembly modulation of gold nanorods (AuNRs) by enzymatic reaction, which is further employed for colorimetric assays of cholinesterase (ChE) and organophosphate pesticides (OPs) in human blood. ChE catalyzes its substrate (acetylthiocholine) and produces thiocholine and acetate acid. The resulting thiols then react with the tips of the AuNRs by S–Au conjunction and prevent subsequent cysteine-induced AuNR end-to-end (EE) self-assembly. Correspondingly, the AuNR surface plasmon resonance is regulated, which results in a distinctly ratiometric signal output. Under optimal conditions, the linear range is 0.042 to 8.4 μU/mL, and the detection limit is as low as 0.018 μU/mL. As ChE is incubated with OPs, the enzymatic activity is inhibited. So, the cysteine-induced assembly is observed again. On the basis of this principle, OPs can be well determined ranging from 0.12 to 40 pM with a 0.039 pM detection limit. To our knowledge, the present quasi pU/mL level sensitivity...

Synergistic Modulation of the Separation of Photo-Generated Carries via Engineering of Dual Atomic Sites for Promoting Photocatalytic Performance

Abstract: The separation efficiency of photo-generated carriers is still a great challenge that restricts the practical application of photocatalytic technology. The design of spatial separation path for photo-generated carriers at atomic level provides an innovative approach to address this challenge. Herein, a facile dual atomic sites strategy, consisting of Cu-N4 and C-S-C active moieties decorated on polymeric carbon nitride (Cu SAs/p-CNS) is reported to simultaneously achieve the highly efficient separation of photo-generated electrons and holes for boosting photocatalytic performance. As a proof of concept, the Cu SAs/p-CNS is successfully applied to the photo-oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-diformylfuran (DFF), which exhibits 77.1% HMF conversion and 85.6% DFF selectivity under visible light irradiation. The activity is considerably higher than that of bulk p-CN, S doped p-CN, and p-CN supported Cu single atom catalysts. Theoretical calculations and experimental results suggest that, during photocatalytic reaction, the isolated Cu-N4 sites directly capture photo-generated electrons, while the surrounding S atoms bear photo-generated holes, which synergistically facilitates the separation of photo-generated carriers and thus results in enhanced photocatalytic activity. This study provides a new perspective for the rational design of high performance photocatalysts at atomic level.
