Bromo- and iodo-bridged building units in metal-organic frameworks for enhanced carrier transport and CO₂ photoreduction by water vapor.

ABSTRACT: Organolead halide hybrids have many promising attributes for photocatalysis, e.g. tunable bandgaps and excellent carrier transport, but their instability constraints render them vulnerable to polar molecules and limit their photocatalysis in moisture. Herein, we report the construction of metal-organic frameworks based on [Pb₂X]³⁺ (X = Br-/I-) chains as secondary building units and 2-amino-terephthalate as organic linkers, and extend their applications in photocatalytic CO₂ reduction with water vapor as the reductant. Hall effect measurement and ultrafast transient absorption spectroscopy demonstrate the bromo/iodo-bridged frameworks have substantially enhanced photocarrier transport, which results in photocatalytic performances superior to conventional met
