The oxidation of reduced products of CO2 on Sb-Pb-Pt/GC yielded current peaks at arrowd - 0.08, 0.2 and 0.3 V, while the oxidation of reduction products on a nm-Pt/GC electrode gave rise a current peak near 0.4 V. The in situ FTIR spectroscopic studies confirmed at a molecule level ...
This work introduces a new technique for the measurement of the equilibrium adsorbed amounts of a multicomponent mixture of gases/vapors on an adsorbent pellet based on Fourier-transform infrared spectroscopy (FTIR). The technique consists of first calibrating the infrared absorption peak areas with ...
Remote sensing techniques are usually safer to deploy than in-situ techniques and can offer attractive spatial coverage, yielding 1-D (path averaged) or 2-D concentration profiles from which more robust flux estimates can be retrieved. OP-FTIR33–35, hyperspectral imagers36,37 and differential ...
evidencing the single-atom state of Co species instead of metallic Co nanoparticles or clusters. The EXAFS data fitting results indicate the main peak is at about 2.0 Å, which value is close to the Co-O bond length of CoO (Fig.3fand Supplementary Table2)27,28. In addition, the coordin...

with CO2.Both disproportion and gasification are remarkably influenced by the content of the residue oxygen in the system.These two reactions cannot be detected when the concentration of oxygen is above 38 × 10-6 and a negative peak on MS signal with m/z 32 appears.%采用TG/FTIR/MS三联机...
In the FTIR spectra of the three In2O3 samples (Fig. S5, ESI‡), four intense peaks centered at 602, 565, 538, and 428 cm−1 are observed, corresponding to the vibration peaks of In–O bonds in cubic In2O3.26 The peak at 1383 cm−1 corresponds to the stretching vibration ...
In all samples, the bending and scissoring vibrations of N–H occurred at 1430 and 1575 cm−1, respectively, suggesting that the amino group is present in these samples. Also, a broad peak around 3434 cm−1is related to the stretching vibration of the O–H bond in the hydroxyl or ...
As illustrated in Fig.10, the peak at 3400 cm−1confirmed the presence of the OH functional group, while the peak at 3300 cm−1identified the amide functional group. Both of them created two valleys adjacent to one another. The carbonyl group appeared at 1700 cm−1. Carbonyl absorption...
