The Raman spectrum of rutile (TiO2) has been recorded using the visible radiations of the mercury arc. The 8 observed Raman lines have been partially explained on the basis of an elementary group-theoretical analysis.doi:10.1007/BF03170832P. S. Narayanan...
Raman spectrum of anatase, TiO2 来自 万方 喜欢 0 阅读量: 530 作者:T Ohsaka,F Izumi,Y Fujiki 摘要: Raman spectra of anatase have been observed in natural and synthetic crystals. Both crystals show the same spectral features. The Raman band occurring at 516 cm−1 at room temperature is ...

为了研究NG-TiO₂的复合光催化剂的分子结构情况,使用拉曼(Raman)进行测试表征,Raman谱图如图4所示。从图4中可以看出,在147 cm⁻¹附近能观察到很强的拉曼振动峰,在395.93、516.52、639.56 cm⁻¹附近的高频区有明显的特征峰,对应...
formation of However, the phase of incident TlaisOer2 layer was still not confirm, so wavelength (λ = 514 nm) was the Raman spectra was measured to analyse the specific peaks. chose to irradiate the fabricated sample. The Raman spectra of The Ag/ tThieO329n8a nnmoc,o5m18p...
与粉体材料相比,TiO2薄膜中纳米 TiO2的量子尺寸效应使得相应的峰位向低波数方向发生位移,而薄膜与基体之间的应力导 致Raman峰位向高波数偏移[14]。从实验结果看,在微波辐射下制成的薄膜样品, 后者可能是主要的。结合图1说明和传统加热方法,微波辐射更有助于活性组分T iO2在载体上的分散,而且使晶体粒子减小。
The great synthetic advantage of extraterrestrial impacts lies in their very broad energy spectrum: via a rovibrational excitation of the reaction components it facilitates a wide variety of chemical transformations. In the current work, we extend this approach towards the synthesis of sugars. We ...
The Raman spectra (Fig. 4a and b) showed that the peak intensities of hydrogenated TiO2 nanosheets was lower than that of TiO2, and its Raman modes at 144 cm−1 and 636 cm−1 were shifted to a higher frequency, indicating that the formation of oxygen vacancies by hydrogen treatment. ...
an additional Raman spectrum was performed (Additional file1: Figure S3). The Raman spectrum for the TiO2nanosheet arrays shows characteristic bands at around 144, 394, 514, and 637 cm−l, corresponding to the Raman active modes in anatase TiO2with the O–Ti–O vibration ofEg,B1g,A1g...
1d). In addition, the Raman spectrum characterized the defects or disorders in DP-CDs (Fig. 1e). The relative intensity of the D-band (amorphous) and G-band (crystalline) was ID/IG = 0.842, which showed that the synthesized DP-CDs were partially amorphous because of the presence ...
