IR spectrum, UV–Vis spectrum, powder X-ray diffraction (XRD) and single-crystal X-ray diffraction. DT–NPY exhibits remarkable photocatalytic activities for the oxidation of cyclohexane to cyclohexanone and cyclohexanol by molecular oxygen under mild conditions. The high catalytic efficiency, high stability and good recyclability of the photocatalyst DT–NPY demonstrates the superiority of the decatungstate
摘要 [(n-C4H9)4N]4[W10O32], 3-amino-4,4'-bipyridine (NPY) 和 Cu(ClO4)2·6H2O 通过扩散法反应生成了一种新型的 3D 十钨酸盐基MOF [Cu(NPY)2(DMF)]2(W10O32)}·DMF·3CH3CN(简称DT-NPY)具有一维亲水/疏水通道,通过元素分析、红外光谱、紫外-可见光进行结构表征光谱、粉末 X 射线衍射 (XRD) 和单晶 X 射线衍射。DT-NPY 在温和条件下通过分子氧将环己烷氧化为环己酮和环己醇表现出显着的光催化活性。光催化剂 DT-NPY 的高催化效率、高稳定性和良好的可回收性证明了 decatungate 嵌入 MOF 优于均相体系和其他多相化方法。
