Visible-light-driven Cr(vi) reduction by ferrocene-integrated conjugated porous polymers via dual catalytic routes

Abstract

Conjugated porous polymers with rapid separation of photogenerated charges and multiple catalytic pathways remain a great challenge. Herein, two ferrocene-based polymers (Fc-CPPs) with high charge separation efficiency and unique dual catalytic routes for Cr(VI) reduction were developed. They exhibited an excellent efficiency, with almost 99% of Cr(VI) readily converted to Cr(III) under 15 min of visible light illumination (λ > 420 nm).
