主 题：oxygen vacancy directional generated W_(18)O_(49) mixed-valence metal oxide electrochemical properties
摘 要：Mixed-valence metallic compounds are a class of functional materials with peculiar electrochemical *** the correlation between defects and corrosion resistance of mixed-valence metallic compounds is a novel and interesting *** an intelligently designed synergistic process of reduction and directed assembly,not only the directional generation of oxygen vacancies along the normal direction of the(010)crystal plane was achieved,but also the W_(18)O_(49)mixed-valence metal oxide(MVMO)with a single crystalline phase and an assembled ordered three-dimensional cluster structure of nanorods was *** attractive effects of oriented oxygen vacancies in W_(18)O_(49)MVMO were ***,the oxygen vacancy channels realized the directional concentrated transport of oxygen atoms to form dense oxide passivation ***,the directional concentrated oxygen vacancies as active centers effectively solved the problem of difficult photoelectron leap and separation of pure-phase semiconductors,realizing photogenerated cathodic ***,the high-energy vacancies endowed the material with antibacterial function,which contributed to the stable existence of the anti-corrosion *** resistance value of W_(18)O_(49)MVMO as an anti-corrosion functional material was increased to more than 4.00 times that of the original metal protection *** experimental results obtained in this research were of great reference value for revealing the intrinsic mechanism of correlation between oxygen defect orientation of MVMOs and electrochemistry.
