Abstract

A metal-free and highly efficient catalytic system involving a task-specific ionic liquid, [P₄₄₄₄][p-2-O], and a pyrene-based conjugated polymer was developed for direct CO₂ capture from air and its further photoreduction to CO under visible light irradiation, affording a CO production rate of 47.37 μmol g⁻¹ h⁻¹ with a selectivity of 98.3%.
