Pt电极表面共吸附层NO和CO氧化还原的CV及原位FTIR研究
NO2 TR-FTIR CH自由基烃燃烧反应机理二氧化氮红外光谱速率常数CH自由基是烃类燃烧过程中反应活性很高的重要的中间产物[1,2].CH自由基与氮氧化物的反应被认为是通过二次燃烧过程减少氮氧化物的主要反应之一, 也是对火焰中氮化物的化学行为建立模型的关键步骤[3].但是,对于CH与NO2反应的研究还不是很深入,到目前为止...

The trend in stratospheric NO2 column at the NDACC (Network for the Detection of Atmospheric Composition Change) station of Jungfraujoch (46.5?? N, 8.0?? E) is assessed using ground-based FTIR and zenith-scattered visible sunlight SAOZ measurements over the period 1990 to 2009 as well as ...
Adsorption of NO and its co-adsorption with oxygen on TiO2 (Degussa P-25) were studied by FTIR spectroscopy. It was found that NO adsorption results in its disproportionation to NO− (1170 cm−1), N2O22− (1335 cm−1) and nitrates (1650–1550 and 1240–1220 cm−1). The ...

Ni-ZSM-5 and Ni/SiO2 samples have been characterized by the IR spectra of adsorbed and coadsorbed NO and CO. Adsorption of CO at room temperature on Ni/SiO2 leads to formation of Ni2+−CO species (ν(CO) at 2192 cm-1) that are easily destroyed by evacuation. The carbonyls formed ...
