| 1 | The corrosion behavior of Mg-Nd binary alloys in the harsh marine environment显示文摘The corrosion behavior of Mg-Nd binary alloys in the harsh South China Sea environment was researched by scanning electron microscopy,energy-dispersive spectrometry and X-ray diffraction analysis.In order to explain the corrosion mechanism,corrosion resistance was analyzed by weight loss rate and electrochemical measurement in the laboratory.With a continuous enlargement of Nd-content,Mg 12 Nd phases increased and multiplied.The weight loss rate of Mg-0.5Nd alloy was 0.0436 mg·cm^(-2)·y^(-1)(0.0837 mm·y^(-1)),whereas that of Mg-1.5Nd alloy was 0.0294 mg·cm^(-2)·y^(-1)(0.0517 mm·y^(-1))during the exposure corrosion in the South China Sea site.The mechanical strength of Mg-1.5Nd alloy was 148 MPa before the exposure in the harsh marine environment,while the residual mechanical strength was merely about 94 MPa after the exposure test.Both Mg-1.5Nd alloy and Mg-1.0Nd alloy occurred the brittle fracture,which resulted that the elongation was nearly equal to zero.The self-corrosion current density demonstrated that degradation rate of Mg-Nd binary alloys was as follows:Mg-0.5Nd>Mg-1.0Nd>Mg-1.5Nd.For the South China Sea corrosion site,a large amount of sea salts exited in the atmospheric environment.Due to the heavy rainfall and high humidity,sodium chloride in the atmospheric environment dissolved,more serious electrochemical corrosion occurred on the surface of Mg-Nd binary alloys. | Quantong Jiang Dongzhu Lu Ning Wang Xiutong Wang Jie Zhang Jizhou Duan Baorong Hou | 2021 | Journal of Magnesium and Alloys2021，9，1： | 3 |
| 2 | Research progress of TiO2 photocathodic protection to metals in marine environment显示文摘Corrosion protection has become an important issue as the amount of infrastructure construction in marine environment increased.Photocathodic protection is a promising method to reduce the corrosion of metals,and titanium dioxide(TiO2) is the most widely used photoanode.This review summarizes the progress in TiO2 photo gene rated protection in recent years.Different types of semiconductors,including sulfides,metals,metal oxide s,polymers,and other materials,are used to design and modify TiO2.The strategy to dramatically improve the efficiency of photoactivity is proposed,and the mechanism is investigated in detail.Characterization methods are also introduced,including morphology testing,light absorption,photoelectrochemistry,and protected metal observation.This review aims to provide a comprehensive overview of Ti02 development and guide photocathodic protection. | WANG Xiutong XU Hui NAN Youbo SUN Xin DUAN Jizhou HUANG Yanliang HOU Baorong | 2020 | Journal of Oceanology and Limnology2020，38，4： | 1 |

| 5 | Electrolyte Strategies Toward Optimizing Zn Anode for Zinc-Ion Batteries显示文摘Zinc-ion batteries(ZIBs)with low cost and high safety have become potential candidates for large-scale energy storage.However,the knotty Zn anode issues such as dendritic growth,hydrogen evolution reaction(HER)and corrosion and passivation are still unavoidable,which greatly limits the wide applications of ZIBs.The states and additives of electrolytes are closely related to these problems.However,there is a lack of systematic understanding and discussion about the intrinsic connection between the states and additives of electrolyte and Zn anode issues.In this review,the basic principles of dendritic growth,HER and corrosion and passivation are fi rstly introduced,and then,electrolyte optimization strategies with the corresponding electrochemical properties are systematically summarized.In particular,the action mechanism of electrolyte additives and the electrolyte states for Zn anode optimization is analyzed in detail.Finally,some unique views on the improvement of electrolyte for Zn anode optimization are put forward,which is expected to provide a certain professional reference for designing high-performance ZIBs. | Zenglong Xu Huiyan Xu Jinfeng Sun Jieqiang Wang Degang Zhao Bingqiang Cao Xiutong Wang Shuhua Yang | 2023 | Transactions of Tianjin University2023，29，6： | 0 |
| 6 | Plasma-inducedε-MnO_(2)based aqueous zinc-ion batteries and their dissolution-deposition mechanism显示文摘MnO_(2)has attracted great interest in working as the cathode of zinc ion batteries.However,the development of high-capacity,high-energy-density,and durable manganese-based cathodes with an easy synthesis strategy and proper energy storage mechanism remains an ongoing challenge.Herein,a facile plasmainduced strategy was demonstrated to introduce oxygen vacancies into theε-MnO_(2),and the obtained oxygen vacancies-richε-MnO_(2)nanosheets(ε-MnO_(2-x))show satisfactory electrochemical performances.Furthermore,an appropriate energy storage mechanism for dissolution/deposition was proposed.Thanks to a synergistic effect of the oxygen vacancies inε-MnO_(2)nanosheets and the exposed free-standing collector for Mn^(2+) dissolution/deposition,theε-MnO_(2-x) nanosheets electrode delivers a remarkable capacity(337 mAh g^(-1)at 0.1 A g^(-1))and exhibits an ultrahigh energy density of 462 Wh kg^(-1)(based on the weights of the cathode active material).Furthermore,impressive durability with 85.9%capacity retention after 1000 cycles was obtained.The superior electrochemical performance makes the plasma-induced strategy promising for designing advanced metal oxide electrode materials for high-performance aqueous zinc ion batteries. | Le Zhang Shuhua Yang Wenqing Fu Yanwei Cui Jieqiang Wang Degang Zhao Chao Yang Xiutong Wang Bingqiang Cao | 2022 | Journal of Materials Science & Technology2022，，32： | 0 |
| 7 | Synergistic combination of a Co-doped��σ-MnO_(2)cathode with an electrolyte additive for a high-performance aqueous zinc-ion battery显示文摘The key challenges in aqueous zinc-manganese dioxide batteries(MnO_(2)//Zn)are their poor electrochemical kinetics and stability,which are mainly due to low conductivity and the inevitable dissolution of MnO_(2).A syn-ergistic combination of a Co-doped��σ-MnO_(2)electrode(Co-MnO_(2))and a Co(CH_(3)COO)_(2)•4H_(2)O(CoAc)electrolyte additive is here developed to design a high-performance aqueous MnO_(2)//Zn battery(denoted as a Co-MnO_(2)//Zn battery with CoAc).The introduction of Co ions(Co^(3+)/Co^(2+))into the��σ-MnO_(2)electrode is achieved via a facile one-step electrodeposition method.Benefitting from the synergistic coupling effect of the Co-MnO_(2)electrode and the CoAc electrolyte additive,the fabricated Co-MnO_(2)//Zn battery with CoAc shows a commendable dis-charge capacity of 313.8 mAh g^(−1)at 0.5 A g^(−1),excellent rate performance,excellent durability over 1000 cycles(∼92%capacity retention at 1.0 A g^(−1))and admirable energy density(439.3 Wh kg^(−1)),which is a significant improvement compared with an un-doped��σ-MnO_(2)//Zn battery. | Shuhua Yang Le Zhang Mengjiao Luo Yanwei Cui Jieqiang Wang Degang Zhao Chao Yang Xiutong Wang Bingqiang Cao | 2023 | ChemPhysMater2023，2，1： | 0 |
| 8 | Developing high photocatalytic antibacterial Zn electrodeposited coatings through Schottky junction with Fe3+-doped alkalized g-C_(3)N_(4) photocatalysts显示文摘Pure Zn coatings easily lose their protective performance after biofouling because they have no antibacterial effect under visible light.In this study,we fabricate a new antibacterial Zn composite coating using electrodeposition to couple Fe3+-doped alkalized g-C_(3)N_(4)(AKCN-Fe)into an existing Zn coating and show that the AKCN-Fe enhances antibacterial property of the Zn coating under visible light.We attribute this enhancement to the high photocatalytic performance,high loading content,and good dispersion of AKCN-Fe.In addition,the photocatalytic antibacterial mechanism of the composite coating is supported by scavenger experiments and electron paramagnetic resonance(EPR)measurements,suggesting that superoxide(·O_(2)^(-))and hydroxyl radical(·OH)play main and secondary roles,respectively. | Ying Gao Xiaofan Zhai Yuxin Zhang Fang Guan Nazhen Liu Xiutong Wang Jie Zhang Baorong Hou Jizhou Duan | 2023 | Nano Materials Science2023，5，2： | 0 |
