Engineering a CsPbBr₃-based nanocomposite for efficient photocatalytic CO₂ reduction: improved charge separation concomitant with increased activity sites.

ABSTRACT: Metal-halide perovskite nanocrystals have emerged as one of the promising photocatalysts in the photocatalysis field owing to their low-cost and excellent optoelectronic properties. However, this type of nanocrystals generally displays low activity in photocatalytic CO₂ reduction owing to the lack of intrinsic catalytic sites and insufficient charge separation. Herein, we functionalized CsPbBr₃ nanocrystals with graphitic carbon nitride, containing titanium-oxide species (TiO-CN) to develop an efficient composite catalyst system for photocatalytic CO₂ reduction using water as the electron source. Compared to its congener with pristine CsPbBr₃, the introduction of TiO-CN could not only increase the number of active sites, but also led to a swift i
