Cu/Cu₂O powder nanocomposites (PNCs) were successfully synthesized by colloidal solution method. To investigate the influence of oxidant agent concentration on the crystallite size and lattice constant of the PNCs, X-ray diffraction (XRD) was utilized to collect the database for crystal growth analysis. Due to the imperfect crystal growth, the Nelson-Riley function and the Williamson-Hall method were used to confirm the precise values of the PNCs. The Rietveld refinement method based on the XRD pattern was used. The XRD results show that the diffraction peaks were mainly assigned to the cubic structure, in good agreement with the ICDD standards. Furthermore, the change in oxidant agent concentration led to a very small change of microstrain in the peaks of Cu/Cu₂O PNCs. Using these methods can aid in the precise study of the crystalline structure of the material, which can then be calculated to adjust the influencing conditions during the synthesis of the material.

采用胶体溶液法成功合成了Cu/Cu _{2 O粉末纳米复合材料（PNCs）。}为了研究氧化剂浓度对 PNC 的微晶尺寸和晶格常数的影响，利用 X 射线衍射 (XRD) 收集用于晶体生长分析的数据库。由于晶体生长不完美，因此使用 Nelson-Riley 函数和 Williamson-Hall 方法来确认 PNC 的精确值。使用基于 XRD 图案的 Rietveld 精修方法。XRD结果表明，衍射峰主要归属于立方结构，与ICDD标准吻合较好。此外，氧化剂浓度的变化导致Cu/Cu _{2峰的微应变变化非常小}O PNC。使用这些方法可以帮助精确研究材料的晶体结构，然后可以通过计算来调整材料合成过程中的影响条件。
