摘要Chemical fixation of carbon dioxide (CO2) to cyclic carbonates was investigated by using bifunctional nucleophile-electrophile catalysts of a metallophthalocyanine-carbon nitride hybrid [MPc/g-C3N4 (M = Co, Cu)] in the absence of any co-catalysts and organic solvents. MPc/g-C3N4 was readily obtained by direct calcination of a mixture of dicyandiamide and metallophthalocyanine under a flowing-nitrogen atmosphere, and the MPc/g-C3N4 prepared at 480 degrees C (MPc/g-C3N4-480) showed the highest catalytic performance toward the cycloaddition reaction of CO2 to epichlorohydrin (ECH). For bifunctional MPc/g-C3N4, the MPc species function as Lewis acidic centers for ECH activation via electrophilic attack; while, the g-C3N4 moiety, possessing abundant and uncondensed species with the forms of primary amine (NH2) groups and secondary amine (C-NH-C) groups at the edges of graphitic sheets as edge defects, acts as an organic base for CO2 activation through nucleophilic attack. The developed MPc/g-C3N4 is stable and insoluble in any commonly used organic solvents and behaves as heterogeneous catalyst, leading to facile separation and recycling in a CO2 fixation reaction.
