2024年9月1日 · The main X-ray diffraction (XRD) peak for CGO and coal-based samples were observed at ∼11° and ∼22–24°, respectively. Ultrasonication of the samples resulted in a reduction of crystallite size and number of layers for all CGO and coal-based samples, confirming both splitting and delamination of carbon layers.

2020年7月1日 · X-ray powder diffraction (XRD) was performed with a Empyrean PANalytical diffractometer and CuK α1,2 radiation. The patterns were analyzed with the GSAS suite software [34].

2020年3月3日 · Samples of pure copper oxide and composites of copper and gallium oxides containing 5, 10, 15 and 20 wt% of gallium precursor (i.e., Ga(NO 3) 3 ·xH 2 O), calculated with respect to copper precursor (i.e., CuSO 4 ·5H 2 O) weight, were structurally analysed by XRD. The obtained patterns of CGO-0, CGO-5, CGO-10, CGO-15 and CGO-20 are shown in ...

Here L, LC, and NC stand for LSCF cathode, LSCF/CGO composite cathode and NiO/CGO composite anode, respectively. The crystal structure of the electrolytes were characterized by X-ray...

2018年1月29日 · We have evaluated the effects of sintering temperature on both the electrochemical and microstructural characteristics of LSCF–CGO cathodes. XRD patterns revealed the chemical compatibility of LSCF with CGO upon high …

2020年5月7日 · Characterization of the Cu/CGO nanocomposites by XPS, XRD, SEM, TPR suggested that this procedure allows obtaining highly dispersed CuO on the cerium gadolinium oxide. Conversion higher than 80% was observed above 600 °C in methane total oxidation. Synthesis parameters affected both properties and catalytic performance.

2020年3月31日 · 通常GO是通过Hummers方法（CGO）制备的，其中石墨与强氧化剂（MnO 4-、FeO 4 2-、H 2 O 2 等）在强酸环境中（浓H 2 SO 4 和HNO 3 ）中反应。然而，这种制备方法很难控制GO的尺寸、层数和结晶度。

Different from the conventional infiltration with a precursor of metal nitrate, here a mixture solution of colloidal CGO nanocrystals and Pr(NO3)3 is used for infiltration to enable the desired...

2024年6月11日 · 在本工作中，钆掺杂二氧化铈基粉末与添加 1%（/w）的 SiO2 和 5%（w/w）的 YO2 共烧，以测试钇离子对改善晶界的作用低品位氧化钆掺杂二氧化铈 (CGO) 电解质晶界区域的电导率。

The catalyst structure was investigated by X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and...
