Graphdiyne (GDY) with a three-dimensional network structure was synthesized on a copper foam (CF) via an in situ Glaser-Hay coupling reaction. A metal-organic framework/GDY composite membrane was designed and synthesized for the first time. CF serves as a template and catalyst for the directed polymerization of GDY membranes. The catalytic activities of HKUST-1/GDY/CF membrane in wet peroxide oxidation of phenol, oxidation of benzyl alcohol, and ring opening of epoxide were studied. The composite membrane has the advantages of appropriateness for continuous operation, simple use process, easy recycling, high catalytic efficiency, etc. It was found that the incorporation of GDY can facilitate electron transfer and effectively improve the catalytic activity of HKUST-1 in membrane catalysis.
通过原位格拉泽-海偶联反应在泡沫铜（CF）上合成了具有三维网络结构的石墨炔（GDY）。首次设计并合成了金属有机框架/GDY复合膜。CF作为GDY膜定向聚合的模板和催化剂。研究了HKUST-1/GDY/CF膜在苯酚湿式过氧化、苯甲醇氧化和环氧化合物开环反应中的催化活性。该复合膜具有适合连续操作、使用过程简单、易于回收、催化效率高等优点。研究发现，GDY的掺入可促进电子转移并有效提高HKUST-1在膜催化中的催化活性。
