Cycloaddition of natural epoxide and CO2 with the help of multi-nuclear phthalocyanine complexes attached to FPS as a nanosaramic

Abstract

This study introduces a three-dimensional, densely packed amide polyphthalocyaninezinc, supported by fibrous phosphosilicate (FPS), for the first time (referred to as Complex@Zn-IL/FPS). The XPS and EDX images confirmed that the Complex@Zn-IL nanosaramic was evenly distributed on the FPS’s surface. The cycloaddition reaction from CO₂ and natural epoxide using Complex@Zn-IL/FPS nanosaramic as catalysts was reported. Furthermore, the catalyst’s structural heterogeneity was examined using various methods, including SEM, FT-IR, XPS, TEM, and TGA. There was no evidence of zinc leaching into the fluid. In addition, hot filtration provided a comprehensive understanding of the catalyst’s heterogeneous nature. The catalyst’s practical and straightforward reusability was noted after the reaction was completed.
