2018年9月20日 · The formation of CeOCl occurred through the reaction Ce3+ + Cl− + [O2−] = CeOCl, where Ce3+ came from both CeO2−x (0 < x < 0.5) and Ce2O3, and the [O2−] was the lattice oxygen. CeOCl started to form in the powder together with ceria at 400&nbsp;°C under hydrogen atmosphere, and the CeOCl content was 91.3% then decreased with increasing ...

2013年8月22日 · CeOCl was synthesized by solid state reaction of cerium oxide with anhydrous cerium chloride and tested in HCl oxidation using various feed compositions at 703 K. X-ray diffraction of post-reaction samples revealed that CeOCl is unstable, in both oxygen-rich and …

以水热法合成的粒径7nm左右的CeO2纳米立方体颗粒为合成CeOCl的原料,在2种不同的反应系统中分别得到了22nm的CeOCl立方体和144nm的CeOCl花形纳米颗粒。

2018年2月5日 · The well-crystallized mixed anions compound cerium oxychloride (CeOCl) was successfully synthesized by a high-pressure solid-state metathesis reaction. The photoluminescence experiment shows that the CeOCl, with a band gap of ∼3.05 eV, has good violet-blue emission properties.

2018年2月5日 · 通过高压固态复分解反应成功合成了结晶良好的混合阴离子化合物三氯氧化铈（CeOCl）。 光致发光实验表明，带隙约为3.05 eV的CeOCl具有良好的紫蓝色发射特性。

2018年10月1日 · CeOCl started to form in the powder together with ceria at 400 °C under hydrogen atmosphere, and the CeOCl content was 91.3% then decreased with increasing synthesis temperature. The growth of...

2019年7月31日 · High-pressure structural evolution of CeOCl, a lanthanide oxychloride, was investigated by in situ high-pressure Raman scattering and first-principles calculations. We report the novel observation of discontinuities in Raman wavenumber at the pressure of approximately 7 GPa, which are related to an isostructural phase transformation caused by ...

2018年9月20日 · CeOCl 的形成通过反应 Ce3+ + Cl- + [O2-] = CeOCl 发生，其中 Ce3+ 来自 CeO2-x (0 < x < 0.5) 和 Ce2O3，[O2-] 是晶格氧。 CeOCl 在 400°C 氢气气氛下开始与氧化铈一起在粉末中形成，CeOCl 含量为 91.3%，然后随着合成温度的升高而降低。

2000年5月15日 · The formation of the CeOCl phase in a Pd(Cl)/CeO 2 catalyst during reduction in hydrogen was studied by HRTEM, XRD, and low-temperature N 2 adsorption (BET). The results indicate that CeOCl crystallites nucleate at (110) faces of CeO 2 crystals at T ≤300°C and then grow by coalescence of existing nuclei and attachment of Ce–O–Cl species ...

2013年8月22日 · CeOCl 是通过氧化铈与无水氯化铈的固态反应合成的，并在 703 K 下使用各种进料组合物在 HCl 氧化中进行测试。 反应后样品的 X 射线衍射显示，CeOCl 在富氧和贫氧中都不稳定使适应。
