这个工作直接观测到了电极表面几种中间体的演化过程,进一步升入了解反应机理。 图13 Time-resolved IR spectra with 1.5 s intervals for 10 min The spectra were taken in 0.1 M KHCO3 D2O electrolyte at -0.94 V on (a) ED-Cu,with baseline spectrum at -0.37 V in CO2saturated electrolyte[17] 3.1....
In this paper we present the results of a Fourier self-deconvolution and least-squares analysis of the MIR spectral data for KZn1−xCoxF3. An interpretation is given in terms of low-lying electronic transitions within the 4T1g(4F) ground manifold of Co2+ ions and their vibronics. We ...
The IR spectrum is collected with the interval times of 0 min, 3 min, 4 min, 5 min, 10 min, 15 min and 20 min for HCN-A, and every 5 min interval for HCN under illumination. Fig. 5. (a) Calculated free energy diagram for the reduction of CO2 to CH3CHO on the HCN and HCN-...
Figure S3. Fourier transform infrared spectroscopy (FT-IR) spectrum of the as-synthesized FePc. Figure 1.(e) HAADF-STEM images of 这种FePc分子的结构可以用红外表征(FT-IR)来证明,根据红外峰,比如说727、1080和1117 cm−1处的峰是C-H键振动,1162 cm−1是C-N和1331 cm−1是C-C振动等等,再...
IR spectrum (Supplementary Fig.2b), and was consistent with our calculated value of 1653 cm−1. Accordingly, as revealed by X-ray photoelectron spectrometry (XPS), an additional N-containing species appeared in the spectrum of the Au/SiO2-Schiff sample, with the lower-binding energy ...
In addition, if the presumed doped oxide consists of metallic Ru clusters, the IR spectrum of the surface exposed to CO would have absorption peaks typical of CO adsorbed on Ru, and we do not observe this. It is possible that during the preparation by the combustion method, the Ru atoms ...
FT-IR spectroscopy was carried out on a PerkinElmer Two spectrometer using an attenuated total reflectance plate. Air was used as a background spectrum. Samples were prepared by drop-casting octane suspensions of the Cu NCs directly onto the attenuated total reflectance plate and leaving to air-dr...
Dielectric mirror is an optical mirror made of thin layers of dielectric coating layers deposited on an optical substrate. We offer dielectric laser mirrors for laser lines, for narrowband or broadband wavelength ranges covering spectrum from UV to IR. Wide selection ...
