Silver nanoparticle-immobilized benzimidazole-linked porphyrin polymers for efficient carboxylation of terminal alkynes with CO2

Abstract

Two highly-loaded, well-dispersed Ag nanoparticle catalysts have been fabricated via controlled thermal reduction and immobilized on the surfaces of benzimidazole-linked porphyrin polymers. These nanocomposites can efficiently catalyze the carboxylation of terminal alkynes with atmospheric CO₂ under mild conditions, exhibiting high efficiency and excellent recyclability.
