catalytic activity among the reported rare earth metal-based MOFs described so far but with the lowest required catalyst loading. In addition, its electrophoretic behavior has been studied in depth, providing a zero-charge point between pH 4 and 5, a peak electrophoretic mobility of −1.553 μm cm V–1 s–1, and a ζ potential of −19.8 mV at pH 10.
一种新的Y基金属有机骨架(MOF)GR-MOF-6,化学式为[YL(DMF) 2 ]·(DMF)} n H 3 L = 5-[(4-羧基苯基)乙炔基] 间苯二甲酸;DMF = N,N-二甲基甲酰胺}已通过溶剂热法制备。结构表征表明,这种新型材料是一种三维 MOF,其中三元配体与 Y(III) 金属离子的配位导致在三个维度上延伸的交叉通道系统。这种材料已被证明是一种非常有效的羰基氰基化催化剂,在迄今为止描述的已报道的稀土金属基 MOF 中的催化活性排名第二,但所需的催化剂负载量最低。此外,还对其电泳行为进行了深入研究,在 pH 值 4 和 5 之间提供零电荷点、-1.553 μm cm V –1 s –1的峰值电泳迁移率和 -19.8 mV 的 ζ 电位在 pH 值10.
