Abstract

A novel porous metal organic framework, La-PTC was synthesized by solvothermal method using a perylene3,4,9,10-tetracarboxylate ligand and lanthanum metal ion. The FTIR analysis showed that La-PTC has a different structure with PTCDA and Na4PTC. The La-PTC MOF has high crystallinity, bandgap energy of 2.21 eV with a maximum absorption area at 561 nm. A rod shape structure of La-PTC has been obtained with the surface area of 22.2364 m2.g−1 and classified into mesoporous material. The La-PTC was relative stable up to 376.93 °C. The LaPTC can degrade 64.76% of MO within ca. 240 min under visible light irradiation with the amount of 30 mg LaPTC. The addition of H2O2 improved the photocatalytic activity of La-PTC with degradation efficiency of 67.02%, 70.00%, and 99.60% for MB, RhB, and MO, respectively. This study presents the fabrication of the light-harvesting metal organic framework, La-PTC and its potential in dyes degradation. Copyright © 2021 by Authors, Published by BCREC Group.

用于光催化降解染料的金属有机框架（MOFs）La PTC光捕获

以苝3，4，9，10-四羧酸配体和镧金属离子为原料，采用溶剂热法合成了一种新型的多孔金属有机骨架La PTC。FTIR分析表明，La PTC与PTCDA和Na4PTC具有不同的结构。La PTC MOF具有高结晶度，2.21eV的带隙能量，最大吸收面积在561nm。获得了比表面积为22.2364 m2.g−1的LaPTC棒状结构，并将其归类为介孔材料。La PTC在376.93°C时相对稳定。在30mg LaPTC的可见光照射下，LaPTC可在约240min内降解64.76%的MO。H2O2的加入提高了La PTC的光催化活性，对MB、RhB和MO的降解效率分别为67.02%、70.00%和99.60%。本研究介绍了光捕获金属有机框架La PTC的制备及其在染料降解中的潜力。版权所有©2021作者所有，BCREC集团出版。这是CC BY-SA许可证下的开放访问文章(https://creativecommons.org/licenses/by-sa/4.0)。
