Two Copper-based Cu3(btc)2 and Cu(Im)2 metal organic frameworks were synthesized and annealed to form nanoporous Cu/Cu2O@C and Cu@N-C nanoparticles for utilization as catalysts in the reduction reaction of aromatic nitro compounds to aromatic amines. All synthesized MOF compounds and MOF-derived nanoparticles were characterized using XRD, Raman, TGA, SEM-EDX and XPS methods. Also, the pore size distribution and surface area of the MOF-derived Cu/Cu2O@C and Cu@N-C nanoparticles were characterized by BJH and BET methods. After characterization, the catalysts Cu/Cu2O@C and Cu@N-C were catalytically tested for the reduction reactions of various aromatic nitro compounds chemically by monitoring via a UV-vis spectrometer. Both catalysts exhibited remarkable results compared with those in the literature. Also, the Cu/Cu2O@C catalyst showed better results than the Cu@N-C catalyst.

开发用于还原芳香硝基化合物的高效铜基 MOF 衍生催化剂

合成了两种铜基 Cu3(btc)2 和 Cu(Im)2 金属有机骨架并退火形成纳米多孔 Cu/Cu2O@C 和 Cu@NC 纳米颗粒,用作芳香硝基化合物还原为芳香胺的催化剂. 所有合成的 MOF 化合物和 MOF 衍生的纳米粒子都使用 XRD、拉曼、TGA、SEM-EDX 和 XPS 方法进行表征。此外,MOF 衍生的 Cu/Cu2O@C 和 Cu@NC 纳米粒子的孔径分布和表面积通过 BJH 和 BET 方法进行了表征。表征后,通过紫外-可见光谱仪监测催化剂Cu/Cu2O@C和Cu@NC对各种芳香硝基化合物的化学还原反应进行催化测试。与文献中的催化剂相比,两种催化剂都表现出显着的效果。还,
