The Selective CO Adsorption and Photothermal Conversion Study of an Azo-Based Cobalt-MOF Material. | LitMetric

AI Article Synopsis

  • - A new metal-organic framework (MOF) named [Co(L)(azpy)] was created using a solvothermal method and analyzed through various techniques like X-ray diffraction and thermogravimetric analysis.
  • - The structure featured a macrocycle formed by two ligands connecting two cobalt atoms, demonstrating a capacity for CO adsorption of 30.04 cm/g, and even higher at 41.33 cm/g under low temperatures (273 K).
  • - The compound also showed promising photothermal conversion abilities when exposed to a 730 nm laser, with a temperature rise and photothermal efficiency of 20.3%, indicating its potential for CO capture and thermal energy applications.

Article Abstract

A new metal-organic framework (MOF), [Co(L)(azpy)] (compound , HL = 5-(pyridin-4-ylmethoxy)-isophthalic acid, azpy = 4,4'-azopyridine), was synthesized by a solvothermal method and further characterized by elemental analysis, IR spectra, thermogravimetric analysis, single-crystal and powder X-ray diffraction. The X-ray single-crystal diffraction analysis for compound indicated that two L2 ligands connected to two cobalt atoms resulted in a macrocycle structure. Through a series of adsorption tests, we found that compound exhibited a high capacity of CO, and the adsorption capacity could reach 30.04 cm/g. More interestingly, under 273 K conditions, the adsorption of CO was 41.33 cm/g. In addition, when the Co-MOF was irradiated by a 730 nm laser, rapid temperature increases for compound were observed (temperature variation in 169 s: 26.6 °C), showing an obvious photothermal conversion performance. The photothermal conversion efficiency reached 20.3%, which might be due to the fact that the parallel arrangement of azo units inhibited non-radiative transition and promoted photothermal conversion. The study provides an efficient strategy for designing MOFs for the adsorption of CO and with good photothermal conversion performance.
