In addition, the iron magnetic nanoparticles were characterized by Fourier transform infrared (FTIR) spectroscopy with Perkin Elmer series. Figure 2 shows the absorption peaks at 440, 580, and...

2008年9月1日 · In this study, a systematic approach based on the application of Fourier transform infrared spectrophotometry (FTIR) was taken, in order to quantitatively analyze the corrosion products formed in the secondary cycle of pressurized water reactors (PWR).

FTIR spectrum and absorption bands of the synthesised magnetite iron oxide nanoparticles are shown in Figure 1. The infrared spectrum of these iron oxide nanoparticles revealed all the expected...

FTIR spectra of (a) Fe 3 O 4 , (b) Fe 3 O 4 @SiO 2 , and (c) modified Fe 3 O 4 @SiO 2 by VTES. In the present study, Fe3O4@SiO2 core–shell microspheres were prepared via two steps. First,...

Fe-O的红外吸收峰一般分为两个区域：高频区和低频区，其中高频区主要包含了Fe-O的伸缩振动，低频区则反映了Fe-O的弯曲振动。 在高频区，Fe-O的伸缩振动表现为两个主要峰，一个位于540-650 cm-1，一个位于400-450 cm-1区间。

2017年12月1日 · In this study, we examine the potential use of FTIR in following the Fe(II)-catalyzed transformation of ferrihydrite (Fh) to more crystalline Fe(III) oxides such as goethite (Gt), lepidocrocite (L) and magnetite (Mag).

1998年3月31日 · The FTIR spectra of well-defined hematite (α-Fe 2 O 3) particles varying in size, shape and internal structure have systematically been analyzed. It has been found that the absorption peak frequencies of the pseudocubic particles are located between the corresponding theoretical peak frequencies of spheres and cubes and shift to lower ...

使用亚微米级纤铁矿和针铁矿参比矿物的特征ftir峰的峰高，在实验误差范围内，ftir结果与xas结果相当。 这与是否由还原Fe（III）的细菌Shewanella oneidensis引发Fe（II）催化的转化无关MR-1或在有或没有乳酸的情况下加入硫酸亚铁铵。

Fourier Transform Infrared Spectroscopy (FTIR) analysis provides information about the chemical bonds and the molecular structure of the material. To examine composition and crystalline nature of the synthesized α-Fe 2O 3 nanoparticles, FTIR measurement is carried out at room temperature in the range of 400-4000 cm-1.

The reactions of an iron electrode in alkaline electrolytes of different concentrations are studiedin-situ using internal reflection and external reflection FTIR spectroscopy. Fe(OH)2 is formed during the reaction Fe(O) → Fe(II) at all investigated concentrations.
