2011年7月15日 · In this paper, we investigate electrochemical properties of TiO 2 NTA electrodes in the presence of H + ion and aqueous redox systems using CV. The protons at the TiO 2 (anatase) surface can affect the process of electron transfer from TiO 2 to the acceptor species in the electrolyte by changing the surface states of the TiO 2 (anatase).

In this study, we introduce a nitrogen-doped TiO2 (N-TiO2) catalyst to create more Ti3+ and oxygen vacancy (OV), which act as active sites for selective oxidation of toluene via activating O2...

2023年7月31日 · A facile and eco-friendly method for activating anodic TiO 2 nanotubes (TNTs) by cyclic voltammetry (CV) is proposed, and photoelectrochemical properties of CV-activated TNTs are compared with those of non-activated TNTs and …

The Au-doped TiO2 exhibited a great improvement in the electrochemical performance at low Au concentrations, whereas the excessive Au concentration on the TiO2 surface exhibited a negative...

2022年6月29日 · In this study, we report the fabrication of TiO2 nanorods by a simple, facile and environmentally benign microwave-assisted hydrothermal technique. The phase purity, structural and morphological examination was carried out by Raman, X-ray diffraction and scanning electron microscopy imaging.

2024年2月17日 · In this study, we employed classic electrochemical techniques including cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) to perform electrochemical characterization on atomic-level single-crystal TiO2 electrodes and extract capacitive and resistive properties of single-crystal TiO2 electrode/solution interface in KCl and ...

2024年1月1日 · In this work, we introduce a useful and efficient strategy to manufacture a long-standing and high-rate carbon-doped TiO 2 (C-TiO 2) as an anode material. Titanium (TiO2) and C-TiO 2 were successfully prepared through hydrothermal method in order to improve the electrical performance of Li-battery.

2023年1月5日 · 厦门大学魏湫龙副教授与加州大学洛杉矶分校Bruce Dunn教授 等人系统地研究了不同颗粒尺寸TiO2 (A)的储钠机制，提出了表面氧化还原储钠反应模型，揭示了颗粒尺寸和比容量之间的关系，并成功解释了以往报道中TiO2 (A)块体和纳米材料之间储钠结果的差异。 研究表明，在首次嵌钠过程中，晶态TiO2 (A)表面3-5 nm厚度层发生了无定形化，并在后续反应过程中一直保持。 当颗粒尺寸远大于表面无定形层厚度时，XRD结果始终表现为晶态结构，而当颗粒尺 …

2010年10月1日 · This paper presents the cyclic voltammetric (CV) studies of solid TiO2 in different molten alkali chlorides using "TiO2 powder modified molybdenum electrodes". The results are important for understanding the cathodic electrochemical process of solid metal oxides in …
