Correlation between XPS, Raman and TEM measurements and the gas sensitivity of Pt and Pd doped SnO2 based gas sensors Nanocrystalline thick-film SnO 2 sensors with different dopants were fabricated by an optimized screen printing process and subsequent annealing. Powders ... J Kappler,N Barsan,U ...
By transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, and X-ray diffraction (XRD), it was revealed that nitrogen dopant obviously enhanced the dispersion of Pt NPs. Strong interaction between Pt and NCNTs was observed. Graphitic nitrogen preferentially...
Highly resolution IR and Raman spectra were measured at low temperature (10 K). Using the molecular parameters of the X-ray determinations normal coordinate analyses based on a modified valence force field have been performed and the normal modes of vibration are assigned. The valence force ...

图2. 催化剂的XRD、Raman、XPS等表征结果 在酸性电解液中,Pt/NP-CNTs表现出极其优异的电催化析氢反应性能:起始电位、η10电位、Tafel斜率、稳定性等重要性能指标均优于商业贵金属Pt/C催化剂。如图3a所示,未负载Pt纳米簇的NP-CNTs载体几乎没有析氢反应性能,而负载Pt纳米簇后,CV曲线中出现了明显的氢析出峰,进一...

First principles calculations were performed on the electronic, vibrational and Raman spectra of substitutional N-, B- and Pt-doped rutile titanium dioxide (TiO$_2$), within the density functional theory (DFT), using the plane-wave pseudopotential method. From the calculated electronic band structur...
A technique to record Raman spectra of deeply coloured solids at low temperature (10 K) is described, using a closed cycle He-cryogenerator and moving the cell by an excentric attachment. The spectroscopic resolution is considerably enhanced as compared to room temperature or 80 K measurements. ...
