The coordination polymers (CPs) of Cu and Zr were synthesized by the hydrothermal method. The orotic acid potassium salt (HKL) was used as a linker, which coordinates via O-O. Whereas, 4,4'-trimethylenedipyridine (4,4'-TMDP) was used as a bifunctional monomer, which coordinates via N-N. The synthesized CPs were characterized by FTIR, P-XRD, TGA, DSC and SEM. The photocatalytic activity was investigated against methylene blue (MB) under sunlight irradiation. Both Cu-CP and Zr-CP exhibited potential activity for the degradation of MB, which was 72 % for Cu-CP and 93 % for Zr-CP. The band gap of the CPs was also investigated, and the observed value was 2.2 eV. The band gap indicates that these compounds could bring breakthroughs as photocatalysts instead of semiconductors. These kinds of CPs could be used for multiple purposes in industry and in a green environment.
采用水热法合成了铜和锆的配位聚合物（CPs）。乳清酸钾盐（HKL）用作连接体，通过O - O配位。而4,4'-三亚甲基二吡啶（4,4'-TMDP）用作双功能单体，通过N - N配位。通过傅里叶变换红外光谱（FTIR）、粉末X射线衍射（P-XRD）、热重分析（TGA）、差示扫描量热法（DSC）和扫描电子显微镜（SEM）对合成的CPs进行了表征。在阳光照射下研究了其对亚甲基蓝（MB）的光催化活性。铜配位聚合物（Cu-CP）和锆配位聚合物（Zr-CP）对MB的降解均表现出潜在活性，其中Cu-CP的降解率为72%，Zr-CP的降解率为93%。还研究了CPs的带隙，观测值为2.2电子伏特。该带隙表明这些化合物作为光催化剂而非半导体可能带来突破。这类CPs可在工业和绿色环境中有多种用途。
