1Synthesis of condensed polynuclear aromatic resin from furfural extract oil of reduced-pressure route Ⅱ显示文摘As an industrial byproduct of oil refining,furfural extract oil from reduced-pressure route Ⅱ with high aromatic content was used to prepare heat-resistant condensed polynuclear aromatic(COPNA) resin for the first time.The basic properties of furfural extract oil and the resultant COPNA resin were characterized by infrared spectroscopy(FT-IR),nuclear magnetic resonance spectroscopy(1H-NMR),thermogravimetric analysis(TGA) and elemental analysis(EA).The result showed that heat treated furfural extract oil was successfully used for the synthesis of heat-resistant COPNA resin.The average structural parameters of raw materials and prepared resin were calculated by the improved Brown-Ladner method,and the averaged molecular structure of the resin was obtained.The reaction mechanism for the synthesis of COPNA resin was suggested as an acid-catalyzed positive ion type polymerization.Wu Mingbo Jiang Wei Wang Yuwei Li Shibin Zheng Jingtang 2013Petroleum Science2013,10,4:10
2Synthesis and Characterization of Condensed Polynuclear Aromatic Resin Derived from Ethylene Tar显示文摘As a kind of low-cost and readily available industrial byproduct, ethylene tar (ET) was for the first time utilized for the preparation of heat-resistant condensed polynuclear aromatic resin (COPNAR). The basic properties of ET and the resulted COPNAR were characterized by FT-IR, 1H-NMR, TGA and elemental analysis. The test results showed that ET with high aromatic content (>50%) was suitable for the synthesis of COPNAR with superior heat resistance. The average molecular structure of ET was obtained by means of the improved Brown-Ladner method, and the reaction mechanism was considered as an acid-catalyzed positive ion-typed polymerization. Our findings have provided a new route to develop ET into technology-added heat-resistant resins.Wu Mingbo Shi Yangyang Li Shibin Wang Yuwei Tan Minghui Wang Ding Zheng Jingtang Tsubaki Noritatsu 2012China Petroleum Processing & Petrochemical Technology2012,14,4:7
3Improvements of heat resistance and adhesive property of condensed poly-nuclear aromatic resin via epoxy resin modification显示文摘A bisphenol epoxy resin was used as modifier to increase the heat resistance of condensed poly-nuclear aromatic(COPNA) resin. The basic properties of COPNA resin and modified resin were characterized by Fourier transform infrared spectroscopy(FT-IR), nuclear magnetic resonance spectroscopy(1H-NMR), vapor pressure osmometry(VPO) and elemental analysis(EA). Average structural parameters of resins were calculated by the improved Brown-Ladner method, and heat resistance of resins was tested by thermogravimetric analysis(TGA). The chemical structure, mechanical properties and heat resistivity of the resin/graphite composites prepared with different resins were compared. The results show that the adhesive property and heat resistance of COPNA resin can be remarkably improved by addition of 5 wt.% epoxy resin. The reason is that the reactions between epoxy groups of epoxy resin and hydroxyl groups of COPNA resin improve the heat resistance and adhesive property of COPNA resin. Electric motor brushes with good mechanical properties and low electrical resistivity were successfully prepared by using the modified resin as binder.Wu Mingbo Wang Yuwei Jiang Wei Li Shibin Sun Qiqian Zheng Jingtang Qiu Jieshan 2014Petroleum Science2014,11,4:5

5Applications of M_xSe_y(M=Fe, Co, Ni) and Their Composites in Electrochemical Energy Storage and Conversion显示文摘Transition-metal selenides(M_xSe_y,M = Fe,Co,Ni)and their composites exhibit good storage capacities for sodium and lithium ions and occupy a unique position in research on sodium-ion and lithium-ion batteries.MxSey and their composites are used as active materials to improve catalytic activity.However,low electrical conductivity,poor cycle stability,and low rate performance severely limit their applications.This review provides a comprehensive introduction to and understanding of the current research progress of M_xSe_y and their composites.Moreover,this review proposes a broader research platform for these materials,including various bioelectrocatalytic performance tests,lithium-sulfur batteries,and fuel cells.The synthesis method and related mechanisms of M_xSe_y and their composites are reviewed,and the effects of material morphologies on their electrochemical performance are discussed.The advantages and disadvantages of M_xSe_y and their composites as well as possible strategies for improving the storage and conversion of electrochemical energy are also summarized.Huijie Zhou Xiaxia Li Yan Li Mingbo Zheng Huan Pang 2019Nano-Micro Letters2019,11,3:4

15Heat treatment-induced Co^(3+) enrichment in CoFePBA to enhance OER electrocatalytic performance显示文摘Increasing active metal sites is a valid approach to improve the catalytic activity of the catalyst. Co^(3+) is the main active metal site of Co-based catalysts. In this research work, through the partial transformation of CoFePBA (CFP) via low-temperature heat treatment, the effective control of the Co^(3+)/Co^(2+) ratio has been achieved. The partial transformation strategy of low-temperature heat treatment can not only maintain the original framework structure of CFP, but also increase more active sites. The characterization results show that the CFP-200 sample obtained via heat treatment at 200 ℃ for 2 h under N2 atmosphere has the highest Co^(3+)/Co^(2+) ratio. As an oxygen evolution reaction electrocatalyst, CFP-200 shows the best electrocatalytic activity among all samples. In 1.0 mol/L KOH electrolyte, the overpotential is 312 mV at a current density of 10 mA/cm2. Therefore, low-temperature heat treatment provides an effective method for preparing low-cost and high-efficiency electrocatalysts.Wenhui Hu Mingbo Zheng Huiyu Duan Wei Zhu Ying Wei Yi Zhang Kunming Pan Huan Pang 2022Chinese Chemical Letters2022,33,3:1
