Monitoring thermally induced structural deformation and framework decomposition of ZIF-8 through in situ temperature dependent measurements

Physical Chemistry Chemical Physics (2017)

Ben Xu Yingjie Mei Zhenyu Xiao Zixi Kang Rongming Wang

ZIF-8 is an easily synthesized porous material which is widely applied in gas storage/separation, catalysis, and nanoarchitecture fabrication. Thermally induced atomic displacements and the resultant framework deformation/collapse significantly influence the application of ZIF-8, and therefore, in situ temperature dependent FTIR spectroscopy was utilized to study the framework changes during heating in the oxidative environment. The results suggest that ZIF-8 undergoes three transition stages, which are the lattice expansion stage below 200 °C, the "reversible" structural deformation stage from 200 to 350 °C, and the decomposition/collapse stage over 350 °C. Our research indicates that the Zn-N bond breaks at a temperature of 350 °C in the oxidant environment, leading to a drastic deformation of the ZIF-8 structure.

Single-Atom-like B-N₃ Sites in Ordered Macroporous Carbon for Efficient Oxygen Reduction Reaction

ACS Applied Materials & Interfaces (2021)

Xuting Li Lili Fan Ben Xu Yanxue Shang Mengfei Li

On the premise of cleanliness and stability, improving the catalytic efficiency for the oxygen reduction reaction in the electrode reaction of fuel cells and metal-air batteries is of vital importance. Studies have shown that heteroatom doping and structural optimization are efficient strategies. Herein, a single-atom-like B-N3 configuration in carbon is designed for efficient oxygen reduction reaction catalysis inspired by the extensively studied transition metal M-Nx sites, which is supported on the ordered macroporous carbon prepared by utilizing a hydrogen-bonded organic framework as carbon and nitrogen sources and SiO2 spheres as a template. The co-doping of B/N and ordered macroporous structures promote the metal-free material high oxygen reduction catalytic performance in alkaline media. DFT calculations reveal that the B-N3 structure played a key role in enhancing the oxygen reduction activity by providing rich favorable *OOH and *OH adsorption sites on the B center. The promoted formation of *OH/*OOH intermediates accelerated the electrocatalyst reaction. This study provides new insights into the design of single-atom-like nonmetallic ORR electrocatalysts and synthesis of ordered macroporous carbons based on hydrogen-bonded organic frameworks.

Ceramic carbon/polypyrrole materials for the construction of bienzymatic amperometric biosensor for glucose

Tian Fm Zhu Ld Ben Xu Zhu Gy

A novel amperometric glucose biosensor was constructed by electrochemical formation of a polypyrrole (PPy) membrane in the presence of glucose oxidase (GOD) on the surface of a horseradish peroxidase (HRP) modified ferrocenecarboxylic acid (FCA) mediated sol-gel derived ceramic carbon electrode. The amperometric detection of glucose was carried out at +0.16 V (vs. SCE) in 0.1 mol/L phosphate buffer solution (pH 6.9) with a linear response range between 8.0x10(-5) and 1.3x10(-3) mol/L of glucose. The biosensor showed a good suppression of interference and a negligible deviation in the amperometric detection.

NiSe2/Ni(OH)2 Heterojunction Composite through Epitaxial-like Strategy as High-Rate Battery-Type Electrode Material

Nano-Micro Letters (2020)

Hao Mei Zhaodi Huang Ben Xu Zhenyu Xiao Yingjie Mei

Abstract Constructing heterojunction is a promising way to improve the charge transfer efficiency and can thus promote the electrochemical properties. Herein, a facile and effective epitaxial-like growth strategy is applied to NiSe 2 nano-octahedra to fabricate the NiSe 2 -(100)/Ni(OH) 2 -(110) heterojunction. The heterojunction composite and Ni(OH) 2 (performing high electrochemical activity) is ideal high-rate battery-type supercapacitor electrode. The NiSe 2 /Ni(OH) 2 electrode exhibits a high specific capacity of 909 C g −1 at 1 A g −1 and 597 C g −1 at 20 A g −1 . The assembled asymmetric supercapacitor composed of the NiSe 2 /Ni(OH) 2 cathode and p-phenylenediamine-functional reduced graphene oxide anode achieves an ultrahigh specific capacity of 303 C g −1 at 1 A g −1 and a superior energy density of 76.1 Wh kg −1 at 906 W kg −1 , as well as an outstanding cycling stability of 82% retention for 8000 cycles at 10 A g −1 . To the best of our knowledge, this is the first example of NiSe 2 /Ni(OH) 2 heterojunction exhibiting such remarkable supercapacitor performance. This work not only provides a promising candidate for next-generation energy storage device but also offers a possible universal strategy to fabricate metal selenides/metal hydroxides heterojunctions.
