Fig. 3.XPS spectra of B-1 and N-12.5 for (c) O 1 s[65]. Non-metal doping can also induce the formation of oxygen vacancies, and the most studied element is N. Theoretical calculations show that the doping of N can induce the reduction of oxygen vacancy formation energy which promotes...
The surface composition and chemical states of related elements are first analyzed by X-ray photoelectron spectroscopy (XPS) (Supplementary Fig.10a). For samples of BNT-OV2 and BNT-OVP subjected to reductive treatment, an evident shift (~0.15 eV) to smaller binding energies is observed in ...
我看文献时经常看到这两个词,很是纠结,氧空位是不是就是氧缺陷啊,哪位达人能给解释一下,在下不剩感激,解释的好一定双手将金币奉上。也不知道我有没有把英文注解搞颠倒,氧空位是不是就是Oxygen Vacancy,大家理解我的意思就好,如果我把两个英文名称搞颠倒了,请帮忙纠正过来,因为我用有道翻译就是这样的,请各位...
(XPS), Brunauer–Emmett–Teller (BET), X-ray photoelectron spectroscopy (XPS), UV–Vis diffuse reflectance and Photoluminescence (PL) spectra have been used to investigate the effects of specific surface areas and oxygen vacancy contents on the photocatalytic properties of mesoporous FTO photocatalysts...
Electrochemical coupling of biomass valorization with carbon dioxide (CO2) conversion provides a promising approach to generate value-added chemicals on both sides of the electrolyzer. Herein, oxygen-vacancy-rich indium oxyhydroxide (InOOH-OV) is developed as a bifunctional catalyst for CO2reduction to...
Their surface Ce3+ concentration was measured by XPS, and their surface oxygen vacancy concentrations and grain size were estimated using Raman spectroscopy. The surface oxygen vacancy concentration was found to correlate well with grain size and surface Ce3+ concentration. When incorporated into a ...
XPS test results show that the solvothermal process with ethylene glycol at 160 °C introduces oxygen vacancy to Fe2O3 photoanode. The tests of electrochemical impedance spectroscopy and photoelectrochemical impedance spectroscopy indicate that the introduction of the oxygen vacancy significantly improve the...
These structures promoted oxygen vacancy formation in CeO2, and this was further confirmed by the Raman and XPS results. Consequently, the PdNi-H catalyst... C Luo,L Chen,AN Alodhayb,... - Catalysts (2073-4344) 被引量: 0发表: 2024年 Theoretical study of oxidative removal on the CeO2...
当退火温度为250℃ ≤ T < 600℃时,薄膜由BM-SCO转变为BM-SCO与P-SCO的共存相(Mix-SCO),薄膜的磁性明显增强,由反铁磁性转变为铁磁性(Tc~180 K).当退火温度达到600℃时,完全转变为钙钛矿型SrCoO3–δ.XPS拟合结果显示,退火后Co的价态发生变化,从Co3+转变为Co4+,即薄膜中的部分氧空位被填充.故退火后...
