| 1 | Nitrogen-doped carbon nanotube/polyaniline composite:Synthesis, characterization, and its application to the detection of dopamine显示文摘Nitrogen-doped carbon nanotubes (N-CNTs)/polyaniline (PANI) composites are developed as an electrode material for biosensors. The morphology, composition, and optical properties of the resulting products were characterized by transmission electron microscopy (TEM), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT-IR), and ultraviolet-visible absorption spectra (UV-vis). Furthermore, N-CNTs/PANI composite was immobilized on the surface of a glassy carbon electrode (GCE) and applied to construct a sensor. The obtained N-CNTs/PANI-modified GCE showed one pair of redox peaks and high catalytic activity for the oxidation of dopamine (DA) in a neutral environment. Differential pulse voltam-mograms results illustrate that the fabricated DA biosensor has high anti-interference ability towards ascorbic acid (AA). In addition, the fabricated biosensor showed superior performances with two wide linear ranges from 1 to 80 μM and from 1.5 to 3.5 mM and a low detection limit of 0.01 μM. | FENG XiaoMiao LI RuiMei MA YanWen CHEN RunFeng MEI QunBo FAN QuLi HUANG Wei | 2011 | Science China Chemistry2011，54，10： | 3 |
| 2 | Defect-poor BaSn(OH)6 enhanced charge separation for efficient photocatalytic degradation of toluene显示文摘Crystal defect is well-known to have a significant effect on the photocatalytic performance of semiconductors. Herein, defect-rich and-poor BaSn(OH)6(BSOH-Sn and BSOH-Ba) photocatalysts were synthesized by exchanging the addition order of Ba and Sn. Results show that the defect-poor BSOH-Ba exhibited more efficient toluene degradation under ultraviolet(UV) light, which could attribute to the great suppression of photogenerated electron-hole(e--h+) pairs recombination by tuning the defect concentration. The low defect concentration in BSOH-Ba finally promotes the charge separation efficiency, the generation of reactive oxygen species(ROS), and the photocatalytic toluene degradation reactions. This work not only provides an effective way to inhibit the recombination of photogenerated carriers and improve the photocatalytic performance, but also promotes the understanding of defective perovskite-type hydroxide for more photoreactions. | Xuemei Wang Xi Zhou Ruiben Jin Tianqi Tan Hao Ma Ruimei Fang Bangwei Deng Fan Dong | 2023 | Journal of Environmental Sciences2023，，12： | 0 |
| 3 | Study on Coconut Shell Activated Carbon Temperature Swing Adsorption of Benzene and Formaldehyde显示文摘Adsorption can be used to recover effectively the volatile organic gases(VOCs)in the exhaust gas from factories through using an appropriate adsorption bed.Due to form a physical or chemical bond,adsorption occurs between the porous solid medium and the liquid or gas multi component fluid mixture.The regeneration capa-city of the adsorbent is as important as the adsorption capacity and it determines the economics of the adsorption system.The regeneration of adsorbent can be realized through changing the pressure or temperature of the system.Here,activated carbon samples from coconut shell were prepared and characterized.Benzene or formal-dehyde in the mixed air was used as the adsorption object,and the adsorption experiment was carried out in a U-shaped bed.Discussed how adsorption was affected by activated carbon type,adsorbate and temperature.The results show that oxidation modifed activated carbon can increase the adsorption effect of form aldehyde,but will reduce the ad sorption effect of benzene,because their ad sorption mechanism is different.At 30℃,the saturated adsorption apacity of AC-0 for benzene is 437.0 mg/g.and that of AC-1 for formaldehyde is 670.5 mg/g.In the experimental range,it is found that the adsorption capacity increases with the decrease of temperature,and their changes are very consistent with the ftted ExpDecay1 function. | Zhiguang Yang Gaojun Yan Xueping Liu Zhengyuan Feng Xinfeng Zhu Yanli Mao Songtao Chen Zhisheng Yu Ruimei Fan Linlin Shan | 2022 | Journal of Renewable Materials2022，10，12： | 0 |
