Using diffuse reflectance FTIR spectroscopy, the stretching vibrations of the terminal Mo= O (995 cm 1) and the bridging Mo-O-Mo (820 cm 1) bands were monitored while MoO 3 powders are heated from 25 to 350掳C at a hydrogen pressure of 6 atm. It was found that some discernible ...

The in situ DRIFTS spectra of the CeO2 sample were collected by using a Bruker Vertex 70 FTIR spectrometer. An acquisition time of 30 s at a resolution of 4 cm−1 was used for the spectrum collection. The DRIFTS cell (Harrick) was equipped with CaF2 windows and a heating cartridge...
These results were further confirmed by energy-dispersive X-ray spectroscopy (EDS), X-ray powder diffiaction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, Thermogravimetry (TG) and X-ray photoelectron spectroscopy (XPS) analyses. 展开 被引量: 4 ...
采用戊二醛共价交联法制备出了聚乙烯亚胺/Fe3O4杂化磁性纳米吸附剂(PEI-Fe3O4).通过TEM,XRD,FTIR,VSM和TGA等手段表征了材料的结构和性质.以甲基橙(MO)为吸附质,系统考... 刘旸,赵雪松,潘学军,... - 《环境工程学报》 被引量: 24发表: 2016年
Characterization results (BET, XRD, XPS, FTIR, and TPR) showed that their structure and properties depend on the composition of the calcined samples and the calcined conditions. Catalytic tests showed that relatively high isobutane conversion and desired product selectivity can be achieved over MoV0.3...
FTIR spectra were recorded using a JASCO FT/IR 4600 spectrophotometer using KBr pellet. The 1H NMR and 13CNMR Results and discussion The nanorods were synthesized in two steps using HDN reagent and were fully characterized. FE-SEM and TEM images of the nanorods were shown in Fig. 1. The ...
The recorded FTIR spectra (see Fig. s4) for undoped sample and samples doped with 10%, 25%, 50%, and 75% Eu3+ showed no significant differences between each other. Spectra consisted of several overlapping strong absorption bands in the range of 500–1000 cm−1. These bands can be ...
