This study utilizes X-ray Absorption Near Edge Structure spectroscopy to investigate the Cu oxidation state in hydrous mafic silicate melts equilibrated under diverse fO2 ( 1.8 to 3.1 log units relative to the Fayalite–Magnetite–Quartz buffer), temperature (1150–1300 °C), and pressure (1.0–...
The zeolite Cu(I)Y is promising for adsorptive removal of thiophenic sulfur compounds from transportation fuels. However, its application is seriously hindered by the instability of Cu(I), which is easily oxidized to Cu(II) even under atmospheric environ
Variations in the oxidation state of copper during CO catalytic oxidation over powdered CuO and Cu 2 O in a gas mixture of 5% CO/He and air (O 2 ) were investigated by means of an appropriate combination of evolved gas analysis, thermogravimetry, XRD, and FT-IR in the temperature range ...
The oxidation state of Cu in Cu-ZSM-5 has been investigated by the X-ray absorption near-edge structure (XANES) spectroscopic method during NO decompositio... DJ Liu,HJ Robota - 《Catalysis Letters》 被引量: 236发表: 1993年 In situ characterization of Cu-ZSM-5 by X-ray absorption spectr...
The right panel highlights the diffraction peaks of CuO visible for used c-Cu2O. We used XPS to determine the oxidation state of Cu at the surface of as-prepared and used c-Cu2O and o-Cu2O. Cu 2p XPS and Cu LMM Auger spectra are shown in Figs. 6 and 7 , respectively. The Cu 2...
