carbon dioxide as a building block in organic reactions

Carbon dioxide capture, storage and utilization, including conversion to valuable chemicals, is a challengingand contemporary scientific issue.This project aims to develop an ecological and reusable material to directly capture carbon dioxide from theatmospheric air and subsequently use it as a “C۱ building block” for the sustainable synthesis of finechemicals. The project is grounded on sustainability, and circular economy pillars, and is aligned with theSustainable Development Goals (SDGs) of the United Nations Agenda ۰۲۰۲. The main purpose is to usefood waste to produce a bio-based carbon material (Biochar) with high CO۰ adsorption ability, which willbe used to develop safe, low energy and inexpensive “direct air capture” processes. The captured CO۰ willbe then extracted from the BIOCHAR material, and used as a green reagent in catalytic reactions/processes.Beyond the development of carbon materials capable to selectively capture carbon dioxide from air, theproject also aims at the design of efficient catalysts, based on metal complexes of porphyrins andphthalocyanines, to efficiently perform cycloaddition reactions of CO۰ to epoxides and aziridines. Some ofthose catalysts will be modulated by the insertion of suitable substituents in the tetrapyrrolic macrocycle, toachieve highly active, chemo- and regioselective systems. The catalysts’ heterogenization will be performedthrough their immobilization into inorganic supports (mesoporous aluminumsilicates, carbon nanomaterialsor magnetic nanoparticles), which is intended to allow their recycling and reuse, while maintaining activityand selectivity features. The driving force is the development of efficient bio-based carbon materials forcarbon dioxide capture as well as active/selective catalysts to promote CO۰ cycloadditions to biologicallyrelevant epoxides and aziridines towards the sustainable synthesis of fine chemicals, namely cycliccarbonates and oxazolidinones with potential biological activity.
