Capturing and Fixation of Carbon Dioxide in Confined Spaces Supported Ionic Liquid Phases

Resumo

Chemical fixation of CO2 for the formation of cyclic carbonates is an excellent strategy to reduce this gas in the atmosphere and invests in the production of value-added chemical products. The utilization of ionic liquids (ILs) immobilized on metal oxide supports represents a significant strategy for atmospheric CO2 mitigation, particularly through the fixation of CO2 into epoxides. In this regard, 1-methyl-3-(3-(trimethoxysilyl)propyl)imidazolium trichlorozincate IL incorporated onto Al2O3 are prepared that represents remarkable catalytic activity for the chemical fixation of CO2 in different with epoxides with 80-90% conversion. The catalytic activity is influenced by the electron-withdrawing groups or low steric hindrance of epoxides.
