In the present work, a new kind of magnetic hybrid based on a unique sulfur rich cadmium coordination polymer (Cd^II-CP) has been prepared with a facile and efficient method via ultrasonic condition. The nano-structure of Cd^II-CP namely, [Cd (SCN)₂L]_n [where L = 1, 1-(1,4-butanediyl)bis(1,3-dihydro-3-methyl-1H-imidazole-2-thione] has been synthesized and fully characterized. The X-ray analysis shows the formation of an undulated polymeric two-dimensional network parallel to the (0 01) plane. The Cd^II centers adopt a trigonal bipyramidal geometry which is an uncommon core for a cadmium CP with CdS₃N₂ nodes. We have immobilized the Cd^II-CP with CoFe₂O₄ nanoparticles to build up Cd^II-CP @CoFe₂O₄ and CoFe₂O₄ @Cd^II-CP hybrids by sonochemical procedure. The photocatalytic efficiency was tested by monitoring the photocatalytic oxidation of cationic and anionic dyes under ultraviolet irradiation. In the dark condition, the Cd^II-CP shows a selective adsorption of anionic dye, while adsorption of the cationic dyes were negligible. Consequently, two independent studies have been performed. For the anionic dye adsorption/desorption behavior were examined, while for the cationic dyes, photo degradation phenomena was investigated. It is worth to note that the nanostructure of Cd^II-CP shows more photoresponse than the bulk Cd^II-CP .The direct excitation of nodes within the Cd^II-CP caused an electron transfer which is responsible for the photocatalytic degradation of dyes. A close inspection on the structure of Cd^II-CP revealed that the presence of nodes greatly improved the electron–hole separation and effectively convert the photo generated active ·OH radicals.

在目前的工作中，已经通过一种简便有效的方法，通过超声条件，制备了一种基于独特的富硫镉配位聚合物（Cd ^II -CP）的新型磁性杂化物。Cd ^II -CP的纳米结构，即[Cd（SCN）₂ L] _n [其中L = 1，1-（1,4-丁二基）双（1,3-二氢-3-甲基-1H-咪唑） -2-硫酮]已经合成并充分表征，X射线分析表明形成了平行于（0 01）平面的起伏的聚合物二维网络，Cd ^II中心采用了不常见的三角双锥几何形状CdS ₃ N ₂节点的镉CP的核心我们已经固定了Cd ^II-CP与由CoFe ₂ ö ₄纳米颗粒以建立镉^II -CP @CoFe ₂ ö ₄和的CoFe ₂ ö ₄ @Cd ^II -CP杂种由声化学过程。通过监测紫外线照射下阳离子和阴离子染料的光催化氧化来测试光催化效率。在黑暗的条件下，镉^II-CP显示阴离子染料的选择性吸附，而阳离子染料的吸附可忽略不计。因此，进行了两项独立的研究。对于阴离子染料的吸附/解吸行为进行了研究，而对于阳离子染料，则研究了光降解现象。这是值得注意的是镉纳米结构^II -CP显示比本体镉更多光响应^II镉内的节点的-CP .The直接激发^II -CP引起的电子转移，其负责染料的光催化降解。对Cd ^II -CP的结构进行了仔细检查，发现节点的存在大大改善了电子-空穴的分离，并有效地转换了光生活性OH自由基。
