A self-assembly of pyridine-2,6-dicarboxylate with Cu(II) and Mn(II) under ultrasonic and microwave irradiation gave the two coordination polymers [Cu(PDA)(H₂O)_1.5]n (1) and [Mn(PDA)(H₂O)_1.5]n (2). Their structures were characterized using IR, elemental analysis, X-ray diffraction (XRD) and spectroscopic methods. The corresponding α-Mn₃O₄ and CuO nanoparticles were synthesized by calcination of 1 and 2 in air at 600 °C. Transmission electron microscopy (TEM) reveals a sphere-like morphology for the Mn₃O₄ nanoparticles. Shrinkage of the particle size from 90 nm (by conventional synthesis of the precursor) to 19 nm (ultrasonic-assisted) takes place, indicating the great effect of ultrasonication. CuO nanoparticles were of semispherical (conventional and ultrasonic-assisted methods) and hexagonal shapes (microwave irradiation) with an average diameter of 7, 15 and 25 nm, respectively. The catalytic performance of the coordination polymers towards degradation of methylene blue and methyl orange in the presence of hydrogen peroxide was studied. Using the same dose, catalyst 1 proved to be more efficient in color removal of both MB and MO than catalyst 2 did. Recycling test for 2 showed that it is a recyclable catalyst with no structural changes over three recycling experiments.

在超声波和微波辐射下，2,6-二羧酸吡啶与Cu（II）和Mn（II）的自组装产生了两种配位聚合物[Cu（PDA）（H ₂ O）_1.5 ] n（1）和[ Mn（PDA）（H ₂ O）_1.5 ] n（2）。使用红外，元素分析，X射线衍射（XRD）和光谱方法对它们的结构进行了表征。相应的α-Mn系₃ ö ₄和CuO纳米粒子通过煅烧合成1和2在空气中在600℃。透射电子显微镜（TEM）揭示了Mn ₃ O ₄的球状形态纳米粒子。粒径从90 nm（通过常规的前体合成）缩小到19 nm（超声辅助），这表明超声处理效果显着。CuO纳米颗粒分别为半球形（常规方法和超声辅助方法）和六边形（微波辐射），平均直径分别为7、15和25 nm。研究了过氧化氢存在下配位聚合物对亚甲基蓝和甲基橙降解的催化性能。使用相同的剂量，事实证明，催化剂1在去除MB和MO的颜色上比催化剂2更有效。回收测试2 结果表明，它是一种可循环利用的催化剂，在三个循环实验中均未发生结构变化。
