Abstract

Herein we propose the utilization of nanosized water domains for photocatalytic CO₂ conversion, by which CO₂ can be efficiently reduced to CO with a CO evolution rate of 682 μmol g⁻¹ h⁻¹ and selectivity >99%. It provides a facile, efficient and adjustable route for photocatalytic CO₂ conversion with water.
