Mixed metal-metal oxide/C (Ag-Cu-CuO/C) nanocomposites were synthesized by the heat treatment of a metal-organic framework under a N flow using the one-pot synthesis method. The as-prepared nanocomposites were characterized using a range of techniques, such as TEM, elemental mapping, XRD, N sorption, UV-Vis DRS, and XPS. The nanoparticles were successfully formed with high dispersion in porous carbon materials and high crystallinity based on the analysis results. The Ag-Cu-CuO/C nanocomposites (35 nm) showed high photocatalytic activity and good recyclability toward the borylation of aryl halides under a xenon arc lamp. This result can enhance the interest in photocatalysis for various applications, particularly in organic reactions, using a simple and efficient synthesis method.
采用一锅合成法，在氮气流下对金属有机骨架进行热处理，合成了混合金属 - 金属氧化物/C（Ag - Cu - CuO/C）纳米复合材料。使用一系列技术对所制备的纳米复合材料进行了表征，如透射电子显微镜（TEM）、元素映射、X射线衍射（XRD）、氮吸附、紫外可见漫反射光谱（UV - Vis DRS）和X射线光电子能谱（XPS）。基于分析结果，纳米颗粒成功形成，在多孔碳材料中具有高分散性和高结晶度。Ag - Cu - CuO/C纳米复合材料（35纳米）在氙弧灯下对芳基卤化物的硼化反应表现出高光催化活性和良好的可回收性。这一结果能够提高人们对使用简单高效合成方法进行光催化在各种应用中的兴趣，特别是在有机反应中的兴趣。
