Rovibrational spectra of the C–O stretch band (ν5) of Ni(CO)4 have been recorded at 0.006 cm1 resolution by coupling a low pressure continuous supersonic jet with a high resolution interferometer. The spectrum has been analysed thanks to the STDS software (see http://icb.u-bourgogne.fr/...
In the 1990s, Iwasita–Vielstich’s team used in situ Fourier transform infrared spectroscopy (FTIR) studies to consider the change of energy of the electronic states of the d orbital of platinum caused by cocatalysts, for example, Ru, resulting in a weakening of the Pt–COads bond. This ...
sp2c-Py-BT COF和imine-Py-BT COF由给电子的苯并芘(Py)和接受电子的苯并噻唑(BT)分别通过Knoevenagel缩合和Schiff碱反应构建(图1a)。(FTIR)对合成的COFs进行FTIR表征(图1b),位于2821和2730 cm-1的两个峰消失,归因于醛的C-H伸缩振动,证明了成功的缩合。 这一结果可通过在约1700 cm-1处C=O拉伸振动显著降...
FTIR−smog chamber systems were used to show that the atmospheric fate of the alkoxy radical (c-C3H5O3)O(•) is decomposition via C−O bond scission leading to the formation of H(O)COCH2OC(O)H (methylene glycol diformate). The IR spectrum of the peroxynitrate (c-C3H5O3)O2NO2...
案例:FTIR谱图求助—求大神分析一个红外光谱谱图 A:可能设备出了故障或者操作问题, 没有吸收峰。 懂红外的帮忙分析一下红外光谱图1141附近那个峰是哪个官能团引起的,红外所测物质为柠檬酸钠辅助水热制备的NaGd(MoO4)2:Eu3+ 1、首先确定羰基的存在与否。
TPD、FTIR和拉曼光谱证明了,C-O键在室温下容易解离。此外,DFT结果进一步证明了,相比于Co基催化剂,LaCoSiHx具有更强的C-O键活化能力,这是由于前者具有更高的电负性、更低的功函数和更高的d能带中心。 文献信息 The Facile Dissociation of Carbon-Oxy...
MoS2 catalysts were firstly prepared over three different alumina supports gamma c-Al2O3, gamma T-Al2O3, and delta-Al2O3 with the same Mo loading per nm(2). Then, using various deposition methods and different Co-precursors as Co(NO3)(2), Co(acac)(2) and Co(CO)(3)NO, Co-promo...
In cytochrome c oxidase electron transfer from cytochrome c to O2 is linked to transmembrane proton pumping, which contributes to maintaining a proton electrochemical gradient across the membrane. The mechanism by which cytochrome c oxidase couples the e
XAFS、XPS、CO-FTIR结果表明,Co原子与表层两相邻吡啶氮以及亚层一吡啶氮配位,价态位于0和+2价之间(图1)。O2-TPD和DFT计算结果显示,单原子Co对O2有强的吸附及解离能力。 图1. Co K-edge的(a)XANES 谱,(b)傅里叶变换R空间和(c)小波变换EXAFS谱。(d)Co/g-C3N4的Co K-edge的k、R空间实验和拟合的...
