Synthesis of Cyclic Carbonate from Carbon Dioxide and Epoxides Using Bicobalt Complexes Absorbed on DFNS.

Herein, a 2D closely packed bicobalt complex supported by DFNS was first provided. The XPS and EDX pictures of the DFNS/(bicobalt complex) catalysts affirmed that bicobalt complex was well spread on the outer layer of DFNS. The CO2/propylene oxide coupling reactions, employing DFNS/(bicobalt complex) as catalysts were announced. In addition, the catalyst anatomical heterogeneity of DFNS/(bicobalt complex) was characterized by various techniques, including EDX, SEM, TGA, TEM, XPS, and FT-IR. No leaching of cobalt into the solution was observed. The catalytic power of our catalyst was compared with literature reported catalysts for the synthesis of cyclic carbonate. lower temperature, the minimum amount of catalyst, lower pressure of carbon dioxide and shorter reaction time were required for CO2 transformation, using DFNS/(bicobalt complex) NPs. Besides, hot filtration presented a throughout understanding of the catalyst's heterogeneous nature. The easy and applied reusability of the catalyst was observed after the completion of the reaction. [ABSTRACT FROM AUTHOR]
