1Hydrothermal Synthesis of MoO_2 and Supported MoO_2 Catalysts for Oxidative Desulfurization of Dibenzothiophene显示文摘A novel method for obtaining spherical MoO2 nanoparticles and SiO2-Al2O3 supported MoO2 by hydrothermal reduction of Mo(VI) species was studied. The obtained MoO2 catalysts show very high catalytic activity in the oxidative desulfurization(ODS) process. The effect of hydrothermal temperature and crystallization temperature on ODS activity was investigated. The ODS activity of supported MoO2 catalysts with various MoO2 contents were also investigated. The mechanism for formation of MoO2 involving oxalic acid was proposed.Wang Danhong Zhang Jianyong Liu Ni Zhao Xin Zhang Minghui 2014China Petroleum Processing & Petrochemical Technology2014,16,4:7
2Solvothermal Synthesis of V_2O_3 Catalysts for Oxidative Desulfurization of Dibenzothiophene显示文摘V2O3 nanoparticles with high surface area have been successfully prepared by a new solvothermal method without using any surfactant and template. The size of V2O3 nanoparticles is mostly equal to 10 nm-30 nm. The highest surface area of obtained V2O3 nanoparticles reaches 49 m2/g. Several kinds of V2O3 catalysts were prepared by different methods. All these V2O3 catalysts obtained thereby showed high catalytic activity for oxidative desulfurization(ODS) reaction by using tert-butyl hydroperoxide as the oxidant. The V2O3 catalyst with a highest ODS activity was obtained under the following conditions: The catalyst was prepared upon using V2O5 as the vanadium source, methanol as the solvent, and oxalic acid as the complexing reagent at a V2O5/oxalic acid molar ratio of 1:2. The process for ODS of dibenzothiophene was carried out under mild conditions(under atmospheric pressure and at a relatively low temperature). The highest ODS activity of the obtained V2O3 nanoparticles can be attributed to their highest surface area.Liu Ni Zhang Minghui Wang Danhong 2014China Petroleum Processing & Petrochemical Technology2014,16,3:6
3Synergistic Effect between Zr-MOF and Phosphotungstic Acid for Oxidative Desulfurization显示文摘PTA/UiO-66 composites were successfully synthesized by the hydrothermal method.The results showed that the synergistic effect between phosphotungstic acid(PTA)and UiO-66 could enhance the oxidative desulfurization(ODS)activity.The XRD results proved that UiO-66 retained its structure in the PTA/UiO-66 composites.The SEM results showed that the PTA/UiO-66 catalysts exhibited regular octahedral shape.The Raman spectra revealed that PTA in the composites retained the Keggin structure.The XPS results showed that the electron transfer occurred from Zr-MOF to PTA.The ODS reaction mechanism was discussed.Electrons transfer from Zr-MOF to PTA can promote the generation of active species(·OH)and thus enhance the ODS activity.This explanation can be confirmed by the formation of oxygen vacancy and W0 as revealed by the XPS analysis.Zong Mengya Zhao Yutong Fan Cunzheng Wang Danhong 2020China Petroleum Processing & Petrochemical Technology2020,22,4:5
4Defect and interface engineering for electrochemical nitrogen reduction reaction under ambient conditions显示文摘Electrochemical nitrogen reduction reaction(e-NRR)under ambient conditions is an emerging strategy to tackle the hydrogen-and energy-intensive operations for traditional Haber-Bosch process in industrial ammonia(NH_(3))synthesis.However,the e-NRR performance is currently impeded by the inherent inertness of N_(2) molecules,the extremely slow kinetics and the overwhelming competition from the hydrogen evolution reaction(HER),all of which cause unsatisfied yield and ammonia selectivity(Faradaic efficiency,FE).Defect and interface engineering are capable of achieving novel physical and chemical properties as well as superior synergistic effects for various electrocatalysts.In this review,we first provide a general introduction to the NRR mechanism.We then focus on the recent progress in defect and interface engineering and summarize how defect and interface can be rationally designed and functioned in NRR catalysts.Particularly,the origin of superior NRR catalytic activity by applying these approaches was discussed from both theoretical and experimental perspectives.Finally,the remaining challenges and future perspectives in this emerging area are highlighted.It is expected that this review will shed some light on designing NRR electrocatalysts with excellent activity,selectivity and stability.Dongxue Guo Shuo Wang Jun Xu Wenjun Zheng Danhong Wang 2022Journal of Energy Chemistry2022,31,2:4
5Effect of Doped Vanadium Dioxide on Oxidative Desulfurization Reaction显示文摘VO2(M) doped with different metals(Ti, Ce, Nb, Zr, W, and Mo) was successfully synthesized by the hydrothermal reduction process using oxalic acid as the reductant. The results showed that doping metals in the VO2(M) lattice could enhance the oxidative desulfurization(ODS) activity. The DSC and Raman spectra revealed that VO2(M) retained its monoclinic structure after doping. Mechanism for the improvement of ODS activity by doping was investigated. Electron transfer to V(V) atom occurs upon doping, and then V(V) changes into V(IV), which can promote the ODS reaction. This explanation can be confirmed by the fact that doping can promote the proportion of V(Ⅳ) after doping as revealed by the XPS analysis.Zhao Yutong Zong Mengya Fan Cunzheng Chen Kun Wang Danhong Zhang Minghui 2019China Petroleum Processing & Petrochemical Technology2019,21,4:4
6Serum bilirubin and ischaemic stroke: a review of literature显示文摘Bilirubin,a product of heme metabolism,is the most potent endogenous antioxidant which increases in many oxidative stress conditions such as stroke.It has been widely known to exert neuroprotective effect on stroke through mechanisms involved in development,therefore,it can influence the occurrence and prognosis of ischaemic stroke(IS).In this review,studies were identified by a comprehensive search of Pubmed,Embase,the Cochrane Library(Cochrane Database of Systematic Reviews,Cochrane Central Register of Controlled Trials(CENTRAL),Cochrane Methodology Register)and Web of Science to examine the correlation between serum bilirubin levels and risks of developing IS as well as IS outcomes.Additional studies were identified by reviewing references and contacting authors.Xiao Wang Danhong Wu Ping Zhong 2020Stroke & Vascular Neurology2020,5,2:3

10Low impedance nature of 12 acupoints on the limbs,and the unexpected dependence on limb angle显示文摘OBJECTIVE: To better understand the working mechanism of acupuncture, we investigated the skin electrical impedance distribution around acupoints, and the impedance changes at 12 original acupoints bilaterally after bending the limbs.METHODS: We measured the skin electrical impedance in three study subjects in the frequency range of 40 to 10 k Hz using the four-electrode method with a sharp probe and a large reference electrode.A measurement matrix of 7 mm × 7 mm with spacing of 2.0(or 3.0) mm was measured to obtain 2 D impedance mapping of acupoints. The impedance spectra of 12 original acupoints were measured at the 0° position and the 90° position.RESULTS: The electrical impedance of some acupoints, such as Yangchi(TE 4), was 16 times lower than that of the surrounding area, showing a recognizable small central area of low impedance with a diameter of less than 4 mm. In contrast, other acupoints, such as Laogong(PC 8), had an electrical impedance that was not significantly different from that of the surrounding area. When the limb was bent from a straight position(0o) to a vertical position(90o), the electrical impedance of the 12 original acupoints showed varied trends, either increasing or decreasing by a factor of up to ten times, or remaining at the same level.CONCLUSION: Not all acupoints tested show the property of low impedance, which might be related to the varied depth of the openings of superficial collaterals. The unexpected dependence of acupoint impedance on limb angle is a novel discovery, which implies that the channel paths are located in interstitial structures in the limbs. It might be possible to determine an optimized limb position for each particular acupuncture treatment in clinical practice.Xu Jingjing Yang Fan Han Danhong Wang Zhenhai Hong Yuankai Han Hongbin Xu Shengyong 2018Journal of Traditional Chinese Medicine2018,38,2:1
