2025年1月1日 · In this study, a Rigaku Smart Lab X-ray Diffractometer (XRD) with Cu K⍺ source (λ = 1.540562 Å) was used for the structural characterization of CuGa 2 O 4 thin films, as it can provide information about crystallographic orientation and the degree of crystallinity. The width of the diffraction peaks in the XRD, known as the FWHM, provides ...

近日，中科院化学研究所韩布兴院士和朱庆宫研究员团队通过简单的两步法构建了具有p-d轨道杂化特征的p区金属Ga掺杂Cu (CuGa) 催化剂，该催化剂可以在安培级电流密度下促进CO2高效电催化生成C2+产物。

2019年5月13日 · The crystal quality of CuGa 2 O 4 film was characterized by XRD and rocking curve measurement. Figure 1 shows the XRD θ–2θ scans patterns of the CuGa 2 O 4 film prepared on β-Ga 2 O 3 (\( \bar{2}01 \)) single-crystal substrate.

2012年12月1日 · Copper gallate spinels, CuGa 2 O 4, have been synthesized by two wet chemical routes: precursor method and self-propagating combustion involving a glycine-nitrate system. All complex precursors have been characterized by chemical analysis, infrared spectroscopy (IR), ultraviolet visible spectroscopy (UV–vis), electron paramagnetic resonance ...

2020年11月5日 · Reacting Cu, GA, and NaOH at a molar ratio of 1:1:2.2 and a temperature of 90 °C, produced mesoporous MOF (CuGA 90–2.2) with a surface area of 198.22 m 2 /g, a pore diameter of 8.6 nm, and a...

thermal expansion behaviour of the resulting CuGa 2 was analysed by syn-chrotron x-ray powder diffraction with supporting observations of single crystal foils in high-voltage transmission electron microscopy. The mechanical properties of CuGa 2 were evaluated by nano-indentation. CuGa 2 …

2017年3月28日 · The XRD data showed that the crystal structure changes from tetragonal chalcopyrite-type CuGaS 2 (0.5 ≤ x ≤ 0.55) to tetragonal stannite-type CuGa 5 S 8 (x = 0.8) through the mixed phase (0.60 ≤ x ≤ 0.75) of the chalcopyrite …

2017年11月17日 · The crystal structure properties of CuGa 2 O 4 powder and post-annealed films were examined by conventional θ-2θ scan X-ray diffraction (XRD) using the Kα emission line of copper. Transmission electron microscope (TEM) was used to observe the crystalline samples in microscopic scale and corresponding selected-area electron diffraction (SAD ...

The structure, morphology, elemental composition and optical properties of the obtained product were characterized by using X-ray diffraction (XRD), Field Emission Scanning Electron Microscopy ...

2019年10月15日 · The ex-situ XRD (Fig. S4) also verifies the existence of LiGa at the lithiation state of the CuGa 2 electrode. During the charge process, the peaks of LiGa decrease and vanish, accompanied by the reoccurrence and intensification of the peaks of CuGa 2 , which implies the total recovery to the pristine state after the first cycle.
