Abstract

Heterostructures of CuFe₂O₄@NH₂-MIL-88B (Fe) were effectively synthesized and utilized as an effective catalyst under visible light and oxidation conditions for the synthesis of quinazolinones. At room temperature, good to excellent yields of the desired products were obtained. In addition, the composite heterostructures that were created showed a higher level of photocatalytic activity when exposed to visible light compared to both CuFe₂O₄ and NH₂-MIL-88B (Fe) individually. In comparison with CuFe₂O₄ and MIL-88B (Fe), the absorption peak of CuFe₂O₄/MIL has increased. Increasing visible light absorption could lead to an increase in electron–hole pair formation, which would improve photocatalytic activity. Furthermore, the incorporation of CuFe₂O₄ to the NH₂-MIL 88B (Fe) surface results in a significant reduction in photoluminescence emission intensity. Moreover, from the perspective of sustainable chemistry, CuFe₂O₄@NH₂-MIL-88B (Fe) demonstrated good recyclability, being recycled six times with little to no loss in catalytic efficacy.

磁性金属有机框架 (MOF) 作为氧化和可见光条件下合成喹唑啉酮的有效光催化剂

CuFe2O4@NH2-MIL-88B (Fe) 异质结构被有效合成，并在可见光和氧化条件下用作合成喹唑啉酮的有效催化剂。在室温条件下，获得了良好至极佳的所需产物产率。此外，与单独的 CuFe2O4 和 NH2-MIL-88B (Fe)相比，所制备的复合异质结构在可见光下显示出更高的光催化活性。与 CuFe2O4 和 MIL-88B (Fe) 相比，CuFe2O4/MIL 的吸收峰值有所增加。可见光吸收的增加可能会导致电子-空穴对形成的增加，从而提高光催化活性。此外，在 NH2-MIL 88B (Fe) 表面加入 CuFe2O4 还能显著降低光致发光强度。此外，从可持续化学的角度来看，CuFe2O4@NH2-MIL-88B（Fe）表现出良好的可回收性，可回收六次，催化功效几乎没有损失。
