Nanoflower Fe-base complex for efficient CO2 fixation under atmospheric pressure

The cycloaddition of CO 2 with epoxides to synthesize valuable chemicals is a promising strategy for advancing carbon neutrality. Herein, a novel iron -based complex (Fe@NTC) with a flower-like structure was employed as an efficient catalyst for the cycloaddition reaction between carbon dioxide and epoxides. Employed in the cycloaddition reaction between carbon dioxide and epoxides, Fe@NTC achieved remarkable conversion of cyclic carbonates, with efficiencies reaching up to 93% yield under UV irradiation. This exceptional performance is largely due to the catalyst 's abundant active sites and superior photothermal catalytic capabilities. Comprehensive characterization techniques revealed that its distinct flower -shaped morphology significantly boosted photocatalytic efficiency. Through meticulous optimization via an orthogonal experimental design, we established ideal reaction conditions, under which Fe@NTC demonstrated consistent stability in repeated cycles. This research not only highlighted the efficacy of Fe@NTC in CO 2 fixation but also paved the way for the development of innovative iron -based catalysts for environmental sustainability.
