Visible-light-driven CO2 reduction and H2 evolution by a ternary conjugated polymer activated with non-precious-metal complexes.

Abstract

Constructing photocatalysts with earth-abundant components for sustainable light-to-chemical conversions is challenging. Herein, we report visible-light-driven CO2 reduction and H2 evolution catalysed by a ternary conjugated polymer as a visible-light photosensitizer with the aid of earth-abundant iron- or copper-based species as a catalytic centre. An auxiliary terpyridine ligand and triethanolamine further activated these metal ions as catalysts.
