2012年12月15日 · Supported Ni catalysts (2 wt.% Ni) were investigated by FT-IR and UV–vis-NIR spectroscopy, using CO 2, CH 3 CN and CO as probe molecules. The supports studied range from acidic (SiO 2), via amphoteric (Al 2 O 3, Mg(Al)O) to basic oxides (MgO, CaO).

2009年1月31日 · IR spectroscopy of low temperature adsorbed CO and CO + NO has been used to characterize the surface species on a 5% Ni-YSZ catalyst. Dispersed surface Ni species are present on the fresh catalyst, essentially formed by Ni 2+, although it is evident that these species are very easily reduced in very mild conditions to zerovalent atomic nickel ...

FTIR spectra of Nickel Oxide nanoparticles are shown in Fig. 2. The band observed at 1638 cm -1 is due to the OH bending of water. A strong band at 610 cm -1 is assigned to the Ni-O stretching...

2003年1月1日 · The present paper reports the Fourier transform infrared (FTIR) spectroscopic study of surface modes in nanostructured nickel oxide, having different average particle sizes ranging from 3 to 16 nm in the far IR region.

NiO nanosheets are prepared by calcination of nickel hydroxide nanosheets, obtained by the hydrolysis of trans-bis (acetato-κO)bis (2-aminoethanol-κ²N,O)nickel (II) complex. BET analysis reveals...

Characterization of obtained nickel-silicon dioxide (Ni-SiO2) nanocomposite was investigated using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Transmission/Scanning...

FT-IR和UV-vis-NIR光谱法以CO 2，CH 3 CN和CO作为探针分子，对负载的Ni催化剂（Ni含量为2％）进行了研究。研究的载体范围从酸性（SiO 2）到两性（Al 2 O 3，Mg（Al）O）到碱性氧化物（MgO，CaO）。

2002年2月19日 · Adsorption of CO on Ni−ZSM-5 reveals the existence of two kinds of Ni 2+ ions, with the respective stretching frequencies being at 2220 and 2212 cm -1. The carbonyl complexes are resistant to evacuation at room temperature, which is explained by the high electrophilicity of cations in a ZSM matrix.

2003年1月2日 · 合成具有3至16nm的不同平均粒径的纳米结构的氧化镍，并在远红外（IR）区域中记录样品的傅立叶变换红外（FTIR）光谱。 发现光谱由表面模式吸收主导，没有对应于本体横向光学模式的明显吸收。

2013年12月1日 · Nickel oxide (NiO) nanoparticles were successfully synthesized by the reaction of nickel chloride with hydrazine at room temperature and thermal decomposition of the precursor nickel hydroxide (Ni(OH) 2) nanoparticles. The products were characterized by X-ray diffraction, Transmission electron microscopy, Fourier transform infrared spectroscopy ...
