因此,本文采用电化学表征手段(图4),如CV测量与原位电化学石英称重(EQCM),确认了超浓电解液体系下存在Al3+与H+的共同嵌入现象。并且通过离位XPS(图3), FTIR(图2d)等表征手段确认了H+的嵌入方式与Al3+不同,主要为在SWCNT表面形成含氧官能团,如-OH,COOH等。 图4 电化学表征及原位EQCM测试揭示了水系环境下的...

采用傅里叶红外吸收光谱(Fourier TransformInfrared Spectrometer,FTIR)来表征颗粒表面官能团的变化情况,仪器型号为 Bruker Vertex 70,扫描范围为 3 500～500 cm-1。采用扫描电子显微镜(Scanning Electron Microscope,SEM)对 Al2O3-AlN复...
Fig. 12 FTIR spectra of products after 120 min The growth mechanism of Al(OH)3 prepared with these four catalysts is proposed in Fig. 13. The oxide film on the aluminum is first destroyed and removed by the alkaline catalyst, and then the reaction of aluminum with water leads to the for...
A mesoporous nanostructured morphology has been observed using HRSEM and HRTEM while FTIR analysis of samples confirmed the composite formation. Further, the XPS has been performed to explain the chemical and electronic states present within sample. The electrochemical analysis of the Al(OH)(3)/Fe...
On the other hand, the CA was increased up to ~ 68° for films prepared with 0.15 wt% of AMH20 and AMH30 particles, also being in agreement with their SEM and FTIR analyses (i.e. reduced –OH groups on the MFC-AMH microdomains). In addition, the volatile 2-propanol present in...
Al可以借用固态核磁分析，OH可以借用FTIR分析
The effect of NaAlO2 and C3A on the formation of thaumasite in cement paste with a S/Al ratio of 9 was systematically studied by XRD, FTIR and NMR, and sodium sulfate solution was selected as erosion medium. The results show that the solub...
