Manipulating the Spin State of Perovskite Cs₃Bi₂Br₉ by Co-Doped for Efficient Photocatalytic CO₂ Reduction.

ABSTRACT: The photocatalytic conversion of CO₂ into the renewable fuels is a promising strategy to address energy and environmental challenges, however, its limited application is mainly attributed to the inefficient charge separation and lack of active sites in conventional catalysts. Here, a spin-polarization strategy using Co²⁺ doping in lead-free perovskite Cs₃Bi₂Br₉ (CBB) synergized with an external magnetic field (MF), is reported to achieve highly efficient CO₂ reduction. The optimized Co-doped CBB (0.2CBB) exhibited a 2.6-fold enhancement in CO production rate (35.04 µmolg^-1h^-1) compared to the pristine CBB, with further improvement to 86.56 µmolg^-1h^-1 under 200 mT MF.
